Sennheiser HDV 820 Headphone Amplifier / DAC Review

Posted on December 18, 2017 by Oscar

Sennheiser HDV 820 Headphone Amplifier / DAC Review

Sennheisers new HDV 820 is a smooth, powerful and versatile DAC/Amp that is all about musical enjoyment and flexibilty.

Pros:

Smooth effortless sound
Detail retrieval
Versatility

Cons:

A little pricey for some

Aesthetics and Build Quality:

Sennheiser have gone away from the silver colour scheme with their latest products, opting instead for a matte black finish. In my opinion the products look a lot sleeker now, and the matte black aluminum casing of the HDV 820 looks superb. The LED status lighting is white and perfectly blends with the whole look.

The build quality is as you would expect from Sennheiser, flawless. The casing is superbly finished and put together, all the sockets are tight and have no play in them. I could not find a single fault with the build and finish of the HDV 820.

Features:

The HDV 820 can be used as a pure amp, pre-amp and also as a DAC/Amp. It has balanced and unbalanced inputs and outputs and supports DSD playback.

On the front panel you have a 6.3mm/3 pin XLR combo single ended headphone out, a balanced 4-pin XLR output and a pair of 4.4mm balanced pentaconn outputs. You also have the power button, source select knob and volume knob.

On the back you have the balanced analogue inputs and outputs, single ended analogue input, gain knob, and finally the optical, coaxial and USB digital inputs.

It is a very versatile unit that can be fitted into any system.

Sound:

The HDV 820 is plenty powerful for most headphones out there, and even does a decent job at driving the HiFiMan HE-6. It is no wonder that it pairs wonderfully with Sennheisers own HD800, bringing out plenty of body, dynamic punch and detail without becoming shouty. The HD800 sound smooth and effortless when paired with the HDV 820, a pairing that is revealing with heaps of detail but never brash or too in your face.

The highlights of the HD800 are accentuated by the HDV 820, offering one of the airiest and widest soundstages of any headphone, orchestral passages are simply sublime. The HDV 820 has no trouble with separating more complex tracks, offering up a textured and well layered sound.

The HDV 820 is not the most neutral and analytical sounding unit out there, it does have a certain smoothness to it but without taking away detail. It won’t become fatiguing to listen to, and is the perfect companion to the HD800.

Conclusion:

The HDV 820 is powerful and versatile making itself at home in any system. It pairs well with many different headphones and has a slightly smoother more laid back sound than some of the other more neutral amps. The HDV 820 is all about musical enjoyment, just sit back and enjoy the effortless sound of your headphones.

Questyle CMA400i DAC / Headphone Amplifier Review

Posted on December 12, 2017 by Oscar

Questyle CMA400i DAC/Headphone Amplifier Review

The Questyle CM400i proves that neutrality really works when it comes to an all in one desktop device. One that works well with sensitive IEM’s all the way up to full size planar magnetic headphones.

Pros:

Neutrality
Detail
Power

Cons:
May sound clinical to some
No analogue inputs

Aesthetics and Build Quality:

The CMA400i is a sleek, matte black DAC/Amp which looks very professional and understated. There are orange LED’s on the front along with the outputs and volume knob; the inputs are on the back. It looks superb, but if you want to change the looks up a little you can buy an optional clear top cover to show off the internals. You can also get an optional desk stand that stands the CMA400i upright to save space.

The CMA400i has a solid CNC machined aluminium shell and feels extremly well built. All the connectors are solid, the buttons precise and the volume control is super smooth. Questyle have made a superbly built unit here, with no flaws in the finish whatsoever.

Features:

The CMA400i is a DAC/Amp, and does not have any analogue inputs, for that you will need the CMA600i which offers a pair of RCA analogue inputs.

The CMA400i has 2 coaxial inputs, 1 optical input and a USB input, so it can be used with a wide range of devices. On the back you have outputs that can be used as line-outputs to an external amplifier or pre-amp output to powered speakers. You get a pair of balanced XLR outputs and a pair of RCA outputs, along with a spdif digital output (USB to spdif converter use).

On the front you have the 4-pin balanced XLR output, a standard 6.3mm singled ended output and a 2.5mm balanced output. This covers the most common single ended and balanced connectors. You have the volume knob and also 2 buttons, one to switch between inputs and one to switch between Amp mode (for headphone and pre-amp use), or DAC mode (DAC mode switches the outputs on the back to line-outputs).

On the bottom you have gain switches, for standard or low gain, this means it can be used with a wide variety of headphones and IEM’s (standard is roghly 2.47x and low is roughly 1.1x)

Sound:

The CMA400i as a pure DAC is superb, it is one of the more detailed and neutral DACs out there not adding any sweetness to the sound. The separation is one of its strong points, and its ability to show up fine detail is also excellent. The DAC won’t smooth over imperfections in recordings, it is very revealing and presents the recording to you as it should be.

Going on to the amp section this is also a more neutral and revealing amplifier, one that could be used in a reference system. The CMA400i could sound cold and clinical to those that are used to smoother sounding amps, however it is not. It is revealing and will show up flaws in the recording, and it will let you hear the real sound of your headphones of choice.

The sound is tight, controlled and detailed, there is no added warmth so careful system matching is a must. The CMA400i is powerful enough for most full size headphones, yet also has a low gain option which can be used in conjuction with sensitive IEM’s and it has a 2.5mm balanced output. The resolution and detail of the sound is superb for the price, you will hear details you have not heard before.

Conclusion:

For an all in one unit the CMA400i is remarkably clean, crisp and detailed. It has excellent control and balance throughout the frequency range and is a great reference setup for testing headphones. It also makes a great desktop setup for most headphones, especially those that lean towards a smoother, warmer sound. Pairing the CMA400i with the Audeze LCD-2 for example really shows what they are capable of with a fun and punchy but not bloated sound. However pairing with the Sennheiser HD800 is perhaps a little too clinical for some tastes.

Shanling UP Portable DAC / Amplifier Review

Posted on August 18, 2017 by John

Shanling UP Portable Headphone USB DAC and Amplifier

Up your portable audio game with the Shanling UP, with excellent detail retrieval and a wide soundstage, a must have for the audiophile on the go.

Pros:

Clarity
Size
Value for money

Cons:

None for the price

Aesthetics, Build Quality and Accessories

The Shanling UP is a tiny little device, the size of a memory stick, with a glossy black front and matter black rear. It has a USB tybe C socket on the top and a 3.5mm headphone jack output on the bottom, on the front an LED will light up telling you the device is on and what sample rate is playing. It is so simplistic and elegant it will fit into any system with ease.

The build quality is excellent with the glass front and the rest of the body being aluminium. Both sockets feel tight, and there is nothing on it to go wrong.

Accessory wise all you get is various cables, which is all that is needed. You get a lightning to USB C, USB C to USB C, Micro USB to USB C and a regular USB to USB C cable, so it covers most phones and PC use.

Ease of use

The UP does not have an internal battery, it just plugs into your device and runs as a DAC/Amp. It should work with most android devices that support OTG accessories, iPhones with lightning port and also PC’s. With the new Windows 10 creators update you no longer need to install drivers.

The devices has no buttons, thus you control the volume level via your phone or PC, I had no issues getting it to work with a Samsung phone, and a regular Windows 10 PC. It is recommended you use the Hiby music app when using the UP.

Optoma NuForce uDAC5 Review

Posted on August 16, 2017 by Oscar

NuForce uDAC5 Mobile DAC/Amp Review

The Optoma Nuforce uDAC5 is an excellent little DAC/Amp that cannot be beaten in size or sound for the price. It is a solid unit with a slightly smooth sound that is sure to please.

Pros:

Size
Build
Sound

Cons:

None for the price

Aesthetics, Build Quality and Accessories

The Nuforce uDAC5 is a tiny little thing, that looks great with a clean metal housing and good sized volume knob. The casing is all metal with a LED light on the front indicating it is on, along with the volume knob and headphone socket, inputs and outputs on the back and that is it.

Built quality is excellent, with the all metal case and solid sockets this little thing is built to survive. The volume pot moves smoothly and everthing feels well put together, the finish of the case is impeccable.

Accessories are not really included, all you get is the DAC, USB cable and quick start guide. I would have like to have seen some rubber feet included, maybe a pair of RCA cables too. But most people already have interconnects so not a huge issue.

Ease of use and Features

The uDAC5 is simple and easy to use, with the latest Windows 10 update, it is plug and play with no need to install drivers. Otherwise the drivers are available from the Nuforce website, I had no issues getting the DAC to work and it just started playing music instantly.

The RCA outputs are controlled by the volume pot, and not a fixed line out. This means you can use this with active monitors, but if you are going into an external amp set the volume to 100%.

It can also be used to convert USB signal to a coaxial for use with an external DAC that has no USB input.

Sound Quality

First off I will say the headphone output has fairly high gain and can drive the Beyerdynamic DT990 600 Ohm with ease, it also worked well with less sensitive IEM’s but won’t be the best match with very sensitive IEM’s unless you lower the volume in windows.

Out of the headphone output the uDAC5 has excellent sound throughout the range, it is not bright and clinical yet still brings out the detail in music. It is a big step up from on board audio out of a PC/Laptop, the sound is sightly warm and euphoric with good separation. I do find the internal amp to be fine for casual listening with easy to drive headphones, but you will notice a difference when going to a full size desktop amp with harder to drive headphones.

Everything is well placed in the mix, the lows hit hard and dig deep, vocals have a sweetness to them that is quite pleasing and highs have good definition and extension, lacking only the micro detail and air that higher end equipment offers.

Acoustic Research M2 High Resolution Audio Player – Expert Review

Posted on July 20, 2015 by Tony

Acoustic Research M2 Review – Android on Steroids

Acoustic Research is one of those old names which has been connected with the world of hi-fi for some 63 years now, although it has changed hands a few times since. Responsible for quite a few innovations over the years, can this brand offer anything new to music fans in 2015? Fully equipped with Wi-Fi capability, the AR-M2 can work with streaming services such as Spotify; so now we’re not limited to the tracks we have stored on our players.

Design and appearance

The M2 is a relatively large and weighty player, with the front side almost completely composed of glass; a fair amount of which is the touchscreen (62mm x 110mm to be exact). The back of the player is bevelled and it settles in the hand well. Its angular form and dark glass screen is reminiscent of a 1980s coffee table, but only a little one.

Key Features

Given the M2 is an android-based player, there’s a fair amount of customisation possible – there’s no bloatware or anything to get in the way, but users can always add items they wish to use. Spotify was installed without a problem, for instance.

Other than the touchscreen, there are 4 buttons on the side for track control and power on/off and a volume wheel on the top. Outputs are limited to headphones and line-level output. There’s a little sliding door for micro SD cards if the internal 64Gb isn’t enough for your music collection, and of course a slot at the bottom for connecting to a computer via USB.

The player can be ‘locked’ for when it’s playing whilst in a pocket or bag; however the buttons on the side still function so there may be some issues there. The volume control wheel on the top is still sensitive when the M2 is locked so again, care is needed.

The player was taken outside on one of the brightest days we have in the UK (we do get bright days) and with the settings adjusted for maximum screen brightness, the screen was clearly legible. The only problem is the fingerprints on the vast expanse of screen which are also clear to see.

The Dac within, a Burr-Brown PCM1794A offers up to 24-bit/192kHz playback and supported formats include DSD, WAV, AIFF, FLAC and ALAC.

Being Android-based, streaming services such as Spotify can be installed on the AR-M2 for use over local wifi networks, making this player more useful still.

Durability & build quality

As alluded to above, the M2 is solidly built and gives the impression of something which will last for a good few years. The back does have a hollow ring to it when tapped with a fingernail, but it doesn’t feel hollow or flex with pressure.

The M2 will be fine in a trouser pocket, but tight trousers might not react too well. Bend over and you might gore yourself – the design is strong and unyielding! The M2 comes with a velvety pouch for protection – ostensibly for the player itself, but it might help avoid the odd nick or scratch elsewhere too.

The buttons on the side of the unit for play controls can be operated even when the unit has gone into standby/hold mode, so fishing the AR-M2 out of a pocket may cause an unintended change of track. Also, the volume control can be operated while in this state. Although it’s firm, it’s loose enough to be operated by material brushing against it in the tight confines of a pocket or bag.

Sound Quality

There’s no question about the power available within the AR-M2; with a HiFiMAN HE-6 attached, volume gets up to a respectable level – even a little too loud for sustained listening, depending on the genre. Likewise with the Audeze LCD-3.

With IEMs such as the Dita Answer (Truth Edition), the AR-M2 is in its element with well controlled bass, excellent space and detail in the midrange, and a rich airiness which brings the best out of both the music and the earphones.

Within the supplied AR player app, EQ settings are possible with many genre-based presets but there’s a limit to the control possible with the rudimentary 5 band on there. This can always change with future updates, however the unadulterated sound of the AR-M2 is perfect.

Pros:

Fast, responsive touchscreen
Large internal memory
Can run apps such as Spotify

Cons:

Side buttons can be pressed while unit is on ‘hold’
Volume control can be accidentally operated

Summary

The Acoustic Research M2 (or AR-M2) is a fantastic sounding player which is well worthy of a position at its price point. Holding it gives the impression that it’s a serious bit of kit, despite all the fun it gives. It has enough power to drive all commonly used headphones well; even 600 ohm cans with sensitivity below 90dB. The large internal memory and the adaptability offered by the Android-based operating system make this a very nice pocketful, although a large one. It’s definitely one for a jacket pocket or bag.

Please take a look at our video review below for more details.

Hidizs AP100 Review – A Sturdy Source Of Solid Sound!

Posted on February 3, 2015 by John

Return to : Best high resolution audio players to buy in 2015 – Expert Reviews

Verdict

The Hidizs AP100 is a great media player. I look forward to future firmware updates but in the meantime the UI is quite useable, and the unit gives a clean, uncluttered sound with a decent amount of power. This is an amazing first effort which begs the question; whatever next from Hidizs?

Pros

Built to last

Neat, useful carry case

Large clear display

Firmware can be updated

Sounds superb at this price point

Internal data/file storage

Cons

Button layout may need getting used to

Micro SD card could be easier to insert and remove

If you like your brand names to look like the first line of an optician’s eye chart, the Hidizs is certainly worth considering – the name might take some getting used to, but it’s plain to see that this player is getting some covetous glances! The Hidizs AP100 has some stiff competition in the low-cost DAP (Digital Audio Player) market, not least from FiiO’s ‘X’ range. The Hidizs AP100 appears to be a halfway house between the Fiio X3 and X5 in terms of size and cost.

Key Features

Inputs and outputs are well represented; both headphone and line-out sockets are present on the top and a separate 3.5mm coaxial in and coaxial out can be found at the base of the unit. Volume buttons are side by side on the front, and on the left side there are both the source/SRC and EQ buttons. Being capable of playback at up to 24bit/192KHz, the SRC button can select the bitrate the player works at. The EQ button scrolls through available presets, and the user can define their own preferred EQ settings.

The case is a really nice design; it is enough to protect the AP100 without bulking it out, and has an understated look much like the player itself. The case is made from a synthetic leather-like material which looks quite durable.

The battery lasts a good long while, and although no precise measurements were taken, there was a good amount of playing time between the ‘low battery’ warning and the player turning off – maybe an hour or two. My experience with the Fiio X3 gives little chance to enjoy music before the unit runs out of power – perhaps 20 minutes at most. Helpfully, the status of the battery is given as a percentage on the screen when charging the unit, so we can make an informed choice of whether to leave the unit charging or to take our chanced with what power is there.

First Impressions

The buttons on the Hidizs AP100 are lovely to press; there’s a great chunky feel to them and they are good solid buttons which will last. Someone said that they are reminiscent of Gameboy buttons – certainly the placement of the volume buttons on the AP100 give a flavour, but they are the kind of buttons that let you know they’ve been pressed – there’s no doubt involved as with touch screens and wheels. The only problem is that Hidizs saw fit to add separate buttons for ‘fast forward/rewind’ – usually the same buttons are used for track skip and forward/rewind, but not on the AP100. Also the ‘back’ button is on the right of the other navigation controls, which makes it feel like a forward/select button; this may lead to a few wrong turns for the uninitiated but it’s easy to get used to.

Sound Quality

Compared to the Fiio X3, the AP100 is a little more accurate and coolish but this is not to say that the AP100 is harsh. Listening to unyielding and brittle-sounding early 80s pop such as Duran Duran is fine on the AP100 but the X3 just gives it a bit more warmth and roundness to a presentation – the AP100 wins in terms of detail.

Compared to the Fiio X5, the sound is extremely similar; the X5 comes across as just a little smoother up top. Soundstage and imaging are similar, but with just a hint of edge to the sound on the AP100 which brings up harmonics a little more.

Added to that, the AP100 holds enough wherewithal to power some less than sprightly headphones such as the HifiMAN HE-400 very well, so the need for a separate amp is lessened.

Summary

An excellent player with a bulletproof design. Solid and reliable, the Hidizs AP100 gives a similarly solid sound and user experience. The sound quality and power gives amazing results, however less sensitive headphones may need a little help. The Beyerdynamic T1, at 600 ohms/102 dB gets up to a good level, but quieter recordings will be lacking in headroom. In our opinion, it bridges the gap between Fiio’s offerings and Astell and Kern’s AK100 but at a very favourable price.

Score 9.0

The Big Apple Rig Shootout – Which DAC and Amp is the Champ?

Posted on December 11, 2014 by John

Here at HiFiHeadphones we’re asked regularly about what amp/DAC combo might make the best job of converting and amplifying your Apple binary music collections. Would it be best to get an all in one solution like the Cypherlabs Theorem or Fostex HP-P1, or get a DAC such as the Cypher Labs Algorhythm Solo with a separate amp?

Further, how does the DAC in the Fostex compare with the DAC in the Theorem if both are connected to the same amp?

The proof of the audio pudding is in shoving the thing into your ears, so here’s our thoughts about how each solution compares!

Firstly, why even bother? The Apple iPod/iPhone has a headphone socket (just) so let’s plug straight in right? There’s nothing wrong with this, and most people find the internal DAC/Amp to be quite satisfactory when used along with their stock white earpods, or any low impedance headphone designed for portable use.

However there are those awkward types who require more power for their chosen headphones; more than the iThingy can put out. Others include those with high value in-ear headphones who will not compromise on audio quality when it comes to the digital to analogue conversion.

The wonderful full size Beyerdynamic T5p and in-ear Sennheiser IE800 were used to ascertain what might comprise the best sound and value for the average portable audiophile.

Fostex HP-P1

The original combined dac/amp for Apple; how does it fare with the new available equipment? When tried with both the Beyerdynamic T5p and Sennheiser IE800 the Fostex HP-P1 does a splendid job. Certainly better than the on-board Apple kit, but other makers have been doing their best in the intervening years of course. With this setup, the HP-P1 filter was slightly more natural sounding so assume the filter is in postion one throughout this test. Being the first up in a comparison, there’s not much to be written now but read on..

Cypher Labs Theorem 720

With the Sennheiser IE800, the Theorem gave a much better impression of control and there seemed to be more space within the midrange region. In comparison, the HP-P1 just got a bit cluttered there and the result was a loss of detail and imaging.

The Theorem compared favourably using the Beyerdynamic T5p too – the soundstage was wider and deeper with better imaging leading to a more immersive 3D sound. The detail level appeared to be the same, but with the Theorem this was smoother and more lush sounding; the Fostex HP-P1 was a little brittle next to this.

Cypher Labs Algorythm Solo with Just Audio AHA-120

I’ve compared this Class A amplifier with the Theorem before; I put it as the Theorem’s spandex versus Just Audio’s silk. Not to say the Theorem is a slouch, but when compared to a Class A amp it sounds slightly less good! And that’s the tradeoff – if you want no compromise in sound quality and wish to pick every component you will pay for it, and you will have to carry it around as well!

DACs Compared Only

For this test I decided to get a decent portable amp (Fiio E12) and compare the Line-Out features of the HP-P1 and Theorem. Things were not all that different in comparitive terms.

The HP-P1 had good detail but the presentation was flat with a limited soundstage; a bit on the dry side.

The Theorem had a wider soundstage but was still a little dry sounding. Detail was similar to the HP-P1 but again with more control.

The Algorythm Solo was a slight let down used in combination with the E12; soundstage was decidedly average with a flat feel to proceedings. Detail was comparitively muddy sounding.

And compared with the E12 amp (with no bass boost), the internal amp of the HP-P1 was slightly darker and more laid back, while the Theorem amp was much fuller and lusher sounding than the Theorem DAC + E12 combo.

Conclusion

The best solution in terms of sound only is the Algorythm Solo/AHA-120 pairing, but this scores lowest in terms of cost, bulk and convenience. Having to keep 3 separate battery operated devices charged is worth considering, and then there’s the interconnects which add cost and lengthen the audio chain. The sound is rich and effortless – a real treat which is earned by those having to carry all that gear!

The Cypher Labs Theorem 720 is the best all-rounder in my opinion – there’s an engaging, exciting energy about the sound from the Theorem which is close to the Solo/AHA-120 combo but it swaps the silky smoothness of the AHA-120 for a more in-your-face powerful sound. Also the amp in the Theorem gives a lushness which is really attractive.

The Fostex HP-P1 is the least impressive of the three; given that it was the first to be introduced this is no surprise. It is still a very competent and fine-sounding unit but has been surpassed since its introduction.

FiiO X1 Review – Fun For Under A Ton!

Posted on November 28, 2014 by John

Return to : Best high resolution audio players to buy in 2015 – Expert Reviews

FiiO X1 – £99.99

We’ve certainly been spoilt by Fiio’s offerings of recent years; it’s a situation that’s all too easy to get used to. First it was amps which got insanely cheap, then DACs. Now we have to get used to the idea of great quality digital audio players for under £100. What’s the world coming to?

Based on the design of bigger brother the X5, the X1 sports a control wheel on the front and buttons for an alternative means of control. Options and tracks can be scrolled through quite easily, and information is displayed clearly on the generously-sized screen. EQ status and battery can be checked at a glance, and other improvements have been made to the player’s software when compared to Fiio’s other players, such as the X3. For instance when moving around the menu system whilst listening to a track, it is now possible to see on the file list which track is playing; but you will need to find your own way to the exact folder where the file is.

Output options are reduced when compared to the X3 and X5; the X1 has one audio output socket only, but is good for both headphones and line-level output. This needs to be selected within the player options menu while no music plays, so don’t worry about the possibility of damaged equipment!

Another very nice feature is the capacity to detect button presses from a headset. When used with headsets on the newer CTIA wiring standard, the X1 should be able to pause, skip track forward and skip track back. This was tried with the new Sennheiser Momentum in-ear model, and the SoundMAGIC E10S.

The sound is amazing for a player under £100. Compared to the X3, the X1 comes across as slightly cooler-sounding and the quality is what we have come to expect from Fiio. The sound gives a slightly brittle impression when compared to more expensive players such as the AK100; but at a fifth of the price the Fiio X1 is a very credible alternative for the cash-strapped music fan!

Audeze LCD-XC Review – Take a Shine to Closed Backs!

Posted on October 16, 2014 by John

Verdict

The Audeze LCD-XC is definitely one of the top-tier headphones available now, and is a worthy stablemate to the similarly closed-back but smoother Fostex TH900.

Pros

Exceptionally comfortable

Sumptuous build quality

Amazing detail

Well balanced

Separation and imaging fully immersive

Sturdy travel case

Cons

May be too heavy for some

In the world of headphones we get the odd celebrity now and again; the flagships sail in and are esteemed due to their value if nothing else. But as with everything, a high price needn’t necessarily equate with a good product. Is this particualr celebrity just famous for being famous, or do they actually have some talent?

Key Features

Those shiny wooden earcups are a treat for the eyes, and the build quality is exceptional. Solid is definitely the word, but this may count against the Audeze LCD-XC as some necks may suffer under the 650g/1.4lb weight; those with the fortitude to ‘press a head’ should be well rewarded though. The tough carry case protects them in transit, and the supplied ribbon-type cable is ‘tangle free’. Also in the case is a little bottle of wax for keeping the shine on the earcups.

First Impressions

Having tried Audeze’s offerings before, my appetite was suitably whetted and it was not disappointed. By now the obvious build quality and good looks are meeting with blasé reactions – we all know what to expect from Audeze! The weight issue was in my mind, but since I’ve been enjoying the HifiMAN HE-400 for some time now with no issues I was not worried, and indeed the LDC-XC’s weight did not bother me.

Sound Quality

I first tried the Audeze LCD-XC with a Chord Hugo; both to feed as good a signal in as possible, and to try the Hugo’s resolution with the LCD-XC. The presentation was very accurate and crisp; I found it just a little too far into bright territory for my tastes. Then I tried the LCD-XC with my humble Fiio X3; the X3’s output is a little warmer than that of the Chord Hugo, and this was reflected within the sound of the headphones. Where before it was a little cold and uncompromising with the K120, it came to life and into colour for me with the X3. The LCD-XC is like a mirror for the amp; it brings out the best traits of the available equipment.

The closed-back nature of this model is possibly a down side, if only because so many great headphones in this price range are open and so have an advantage in terms of soundstage. As we all know however, isolation is often necessary if we aren’t to be distracted (and don’t want to disturb others), and the LCD-XC does not sound like a closed headphone. The soundstage is appreciably wider than the physical limits of the headphones, and the closed nature of them does not remain so obvious when in use.

Summary

With the asking price in mind, it’s no surprise to learn that this is an exceptionally competent headphone which can hold its own among some cutting-edge competition. If you are considering a highend closed-back model and you find the Fostex TH900 a little smooth, the Audeze LCD-XC may be just for you.

Score: 9.5/10

FiiO E18 Kunlun Portable Smartphone Amp/DAC Review

Posted on September 25, 2014 by John

Verdict

We are impressed with the sound quality and power which the Fiio E18 provides; together with the mobile DAC functinality and everything else, nothing gives better value for money. However, it would have been much better (and safer) to have that gain switch recessed, or indeed buried into the side of the unit, rather like the E12. There’s no way we would chance using the E18 with an IEM whilst out and about. Either that prominent gain button should be ripped off or the switch covered up with tape, to save our ears from a possible bashing. Similar with the track/play/pause controls on the side of the unit – these can be swithed and operated all too easily.

Pros

Great Value

Oodles of power

Extra functionality with smartphones

Cons

Gain switch and track select buttons too prominent

The Swiss have enjoyed enormous success with their pocket knives, they are handy and can do a variety of jobs. However if wishing to hack your way through the jungle, a 3-inch blade is going to keep you busy.

Up until recently, portable headphone amps appear to have been aimed at providing a good level of power, or a lot of features. The Fiio E18 changes this, as it can accept a digital signal from a multitude of handsets as well as PC, and amplify enough to power any less-sensitive headphones up to 600 Ohms! Please check the E18 Kunlun page on Fiio’s site (http://www.fiio.cn) for exact details on compatibility.

Key Features

The E18 is a no-nonsense design like the E12, but with a few more tricks up its sleeve. DAC functionality combined with track select controls make this a versatile and useful addition to any portable set-up. Gain and bass boost controls will help get your preferred sound from a vast array of headphone models.

First Impressions

The track skip/back buttons on the side along with play and pause are handy, but it would have been preferable to have seen these recessed – unrequested track skips are an annoyance. Bass boost and gain switches are placed near the volume pot on the top end, and there’s little to prevent accidental operation of the gain switch. Accidental operation of the gain switch could potentially be quite damaging if wearing sensitive IEMs.

There’s a switch on the opposite end to select the source for the DAC (PC or phone) and also there’s the option of using the E18 as a power source itself; this was tried with Fiio X3 and smartphone – they both started accepting a charge, although this smartphone is not compatible with the DAC.

The outward design is not dissimilar to that of the E12 which is an amplifier only. It has been mentioned that the E12 is a little better in terms of amplifier quality, as well as more powerful. But the question everyone wants to know the answer to is ‘will it power my headphones?’ and the answer is very likely to be yes.

The E18 was tried with the AKG K240 DF (600 ohms, 88dB sensitivity) and the dial wasn’t turned all the way up – it was ear splittingly loud with room to spare! The E18 should be able to drive anything the modern world has to offer, within reason. The manuafacturer states an impedance range of 16 – 150 ohms, but there’s nothing like trying these things. So long as your recording is done well (and not extremely quiet), the E18 is enough to really blast it out.

Sound quality

The Fiio E18 was run from a PC to test DAC functionality and quality. It was up against an X3 and E12 together, which seemed like a fair match. A 600 ohm Sennhieser HD540 was used.

The E18 appeared to give better resolution; sounds were relatively flat and dull on the X3/E12 combination. I decoupled the X3/E12 rig and plugged into the X3 alone; predictably, things improved in terms of details due to fewer connections in the chain, but the relative lack of power took some of the wind out of my X3’s sails. Bass and hats were pushed back a little.

Summary

With the wants and needs of the average portable audio fan growing all the time (in part helped along by just this sort of product!) the Fiio E18 tries to tick as many boxes and cover as may bases as it can, and it does a great job of all of them.

Score: 8/10

HIDIZS AP100 Digital Audio Player (DAP) – HifiHeadphones Mini Review

Posted on September 10, 2014 by John

RRP – £230-£250

If you like your brand names to look like the first line of an optician’s eye chart, the Hidizs AP100 is certainly worth considering – the name might take some getting used to, but it’s plain to see that this player is getting some covetous glances!

The AP100 has some stiff competition in the low-cost DAP (Digital Audio Player) market, not least from Fiio’s ‘X’ range. The AP100 appears to be a halfway house between the X3 and X5 in terms of size and cost, but how about sound quality?

The same can easily be said – compared to the Fiio X3, the AP100 is a little more accurate and coolish but this is not to say that the Hidizs AP100 is harsh. Listening to unyielding and brittle-sounding early 80s pop such as Duran Duran is fine on the AP100 but the X3 just gives it a bit more warmth and roundness to a presentation – the AP100 wins in terms of detail.

With the default firmware, tracks stood a good chance of having the first second chopped off if selected from the track list on the device, but this was fixed after upgrading to V1.31067. One problem I had after upgrading was that the unit reverted to its native Chinese language – there was no clue how to get it back to English again. Luckily I found the option in the menu as the only item with 2 Chinese characters. Select this and you’ll see ‘English’ in the sub menu.

The buttons on the Hidizs AP100 are lovely to press; there’s a great chunky feel to them and they are good solid buttons which will last. The only problem is that Hidizs saw fit to add separate buttons for ‘fast forward/rewind’ – I’m so used to using the same buttons for track skip and forward/rewind that I keep skipping tracks by accident. Also the ‘back’ button is on the right of the other navigation controls, which makes it feel like a forward/select button; this may lead to a few wrong turns for the uninitiated but it’s easy to get used to.

There’s a little flap in the case which is held shut by velcro. It took a while to figure out but this is for spare micro SD cards; just be aware that you may need tweezers to remove them again. SD cards can be changed simply in the device, however a tool or long fingernail is required to ‘click’ it into place and retrieve it.

I did also notice a problem with the track list on the player – select ‘track 1’ for instance on the track list and skip forward a couple of tracks via the play screen. Then on going back to the track list, ‘track 1’ is still highlighted as if it is still playing. Perhaps this will be addressed in future firmware updates.

Summary

A good little player; I look forward to future firmware updates but in the meantime the UI is quite useable, and the unit gives a clear uncluttered sound with a good amount of power. A great first effort which begs the question: whatever next from Hidizs?

Chord Cable Interconnects – To The Test

Posted on September 9, 2014 by John

The overriding opinion of those who stick with their free RCA interconnects (often provided with Hi-Fi seperates) is that any money spent on upgrading them is wasted. Quality cabling is a slightly alien concept to be fair; the signal passes from A to B anyway, why spend money on cables which will achieve the same end?

Speaking as someone who has thought exactly this in their time, I was interested to know the actual difference between some of Chord’s offerings, and the skinflint equivalent. Is any improvement noticeable at all, how is it better, and is it worthwhile?

To determine this, my colleague John set up a blind test between a studio grade RME audio interface taking a signal from a computer, and a Graham Slee Solo Ultra Linear. These great amplifiers can switch between two inputs using a control on the front of the unit so is perfect for A/B tests. The inputs of the Slee amp came from the same source but using either the high end Chord Anthem Reference cable, or the entry-level Crimson cable.

Being an informal and quick test, rigorous procedures were not followed; I was aware of the cables being compared and it was just me doing the test. I operated the switch myself to select the cables, but I did not know which cable was feeding which input.

Feeling a little nervous, I noted down some of the impressions I got from listening to Level 42’s ‘Something About You’ through a Fostex TH900, with a Grado PS1000 ready for another listen later. I was encouraged to find that perceived differences were quite easy to spot.

Bell sounds which are pure and stand clear of the mix sound flatter and harder to pick out.

A synth with a bit of distortion on it (starts on beat 3 of the song) sounds as if it is going through a bit-depth reduction effect or ‘bitcrusher’.

The bass is slightly muddier with less definition.

Backing vocals are blended together and less distinct; voices are cleanly separated with the Anthem Reference cables.

Hi-Hats are more splashy and ill-defined.

Not surprisingly I guessed the correct channel for the cheaper Crimson cable; the blind test showed very clearly the differences between the cables.

I then swapped headphones to the Grado PS1000 – an open headphone of similar quality to the TH900. I found that the PS1000 made it more of a challenge to spot differences but they were still there. Another thing I noticed was a loss of soundstage height with the PS1000 when listening to audio through the cheaper Crimson cable.

In the spirit of further thorough experimentation, the “free with hifi separates” cable was tried. Predictably, the differences were more marked.

The bells sounds are flat and dull.

The distorted synth sound requires focused attention to hear through the mix.

Bass is flatter and flabbier.

Backing vocals are more blended; both blended together and with the rest of the music.

Hi-Hats sound more like brief bursts of white noise than cymbals.

The overall impression was of an old cassette recording, relatively speaking. The soundstage was practically limited to the width of the headphones , and high frequencies are messy and splashy. There was a large portion of distortion throughout.

Verdict

Although premium cables like the ‘Anthem Reference’ cables may be out of immediate reach for the average listener, I found that the entry-level ‘Crimson’ model is certainly a worthwhile improvement over the generic black/grey RCA cables. At £55, it is clear to see that this represents great value considering the sonic improvements it offers.

Chord Electronics Hugo review

Chord Electronics Hugo review

Introducing the unassuming Hugo from Chord Electronics; the company which is now causing ripples in the portable audio world with this fantastic device.

Time and again we hear that headphones can mean a huge leap in sound quality; but equal to that is the process by which a particular signal reaches the headphones. Get both right and the effect is no less than sublime.

The Hugo is both a DAC and an amp, with a battery which can last a good while between charges, considering the processes it has to power. There are numerous options when it comes to connectivity, even a bluetooth input is available among the more traditional ins and outs.

The Hugo is built from aircraft-grade aluminium and it almost feels as if it designed for military purposes. Also the input controls are in keeping with this theme; they are obviously built to last also, particularly the large recessed volume control which is hard to knock or move accidentally.

The sound of the Hugo is probably better than a lot of people can imagine; the level of detail and sense of space one can glean from a given recording is out of this world. This is due to the DAC in the Hugo being designed for the Hugo; other designs take pre-existing DAC chips and implement them the best they can.

It consists of a field-programmable gate array, which is configured from the ground up by Chord. Basically it is a custom-made computer which specialises in the highest quality signal conversion.

Inputs include Optical/Toslink, Coaxial, bluetooth, and USB; with an extra HD USB input for operation to 384kHz in PCM format. Outputs feature 2 x 3.5mm sockets (these are slightly recessed and may give trouble, for instance with Earsonics in-ears), one 6.35mm socket and stereo RCA outs. Chord is aware that the Hugo is likely to be used as a DAC for full-size systems and accordingly it is possible to set the output volume to line-level for this purpose.

The effect of all this extra detail (even with 44.1kHz/16-bit recordings) is to vastly increase the sense of space and movement within the performace or recording, making it so much more realistic and captivating. Frequency response is virtually unchanged, so your favourite headphones should not take any rapid departures from their usual sound if used with the Hugo.

It is difficult to get across how much better music sounds with the Hugo, while nobody is a stranger to the potential benefit of the money this item costs! Therefore we welcome enquiries about our listening room; we are confident that the sound of the Hugo will alter your perceptions..!
