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.

As a pure DAC the uDAC5 is clean and clear without any real flaws, it works really well in any system providing a big step up from on-board audio. I feel there is still a slight smoothness to the overall sound which does get rid of any potential harshness but can slightly hide some micro detail.

Conclusion

For the price the Nuforce uDAC5 is an excellent piece of kit, it would be perfect for a coffee shop setup, or a small office rig, it is also perfect as a DAC for active desktop monitors and to feed an external amp at home.

It is not for driving really demanding headphones to their full potential, it is for casual listening and getting better sound out of a PC on a budget, and for this purpose it is a no brainer.

Shanling H1 Portable Headphone Amplifier Review

We’ve been treated to a few of Shanling’s products lately; as well as the excellent M1 and M2S players, this little amp promises to give brands like Fiio a run for their money! The entry-level portables market has been truly cornered by Fiio in recent years, so it will be interesting to see what impact Shanling can make here.

Pros:

  • Small, handy unit
  • Thoughtfully designed volume control
  • Well constructed

Cons:

  • None

Design and Appearance

The Shanling H1 amp is a small unit, being 7cm x 6cm and about 1.5cm thick; about half the size of the average mobile handset. The edges are bevelled and the unit feels good in the hand, with enough weight to feel substantial for its size, although the unit is itself not heavy.

Key Features

The main feature is the recessed knurled volume knob which is centred on one side of the amp, which is protected from accidental operation by the amp’s housing. Power/charge lights are on the top, plus there’s a gain switch and micro-USB socket on the rear for charging. That’s it! The H1 is as simple as it gets for an amp, and it’s all that’s needed.

Durability and Build Quality

The Shanling H1 headphone amp is constructed from aluminium and has a pretty solid feel about it. It will probably have no problem being dropped occasionally, but we’ve not tried this here! The volume knob has a smooth, solid feel as it’s turned and it has enough stiffness not to be operated accidentally whilst in the pocket.

Sound Quality

This amp goes loud for its size; we couldn’t resist pairing it up with a HiFiMAN HE-6 which is notoriously difficult to drive. On the low gain setting, and using an incoming line-level signal, the volume goes up to hearing damage levels with the HE-6 on some pieces. Not bad! Of course, we don’t recommend this pairing for getting the best out of the HE-6!

The H1 is designed for portable use, so was tried versus being directly connected to a cheap phone with portable earphones . The sound is faithful and quite neutral, although there is a little more thump coming through with the sub-bass. Music appears to be more relaxed and natural through the amp, where it sounds a little strained with a direct connection. Listening to this amp with a pair of SoundMAGIC E80 earphones is actually very enjoyable!

Summary

Shanling’s new H1 portable amplifier is a palm-sized affair, but Fiio had better start making room anyway!

Do I Need A Headphone Amplifier? – Buying Guide

What’s the point of a headphone amplifier?

One question we get asked a lot is ‘do I need a headphone amplifier?’ This article will inform you of the benefits of adding an amplifier to your existing setup, or buying an amplifier with your new headphones.

When you’re buying some new headphones it’s always good to think about what your source will be; whether it’s an iPhone, Laptop, DAP (Digital Audio Player), your home HiFi or a bit of everything, figure out which has the lowest output and if it can drive your chosen headphone. So if you use a mobile phone as your main source and you’ve decided on some Shure SE535 earphones which are hard to drive, you will need a headphone amp to add some extra power so you can get the most from your new purchase.

There are plenty of headphones designed to be used with mobile phones and other low powered portable devices; these headphones generally have low impedance (up to 32ohm) and high sensitivity (100db and over) so they are very easy to drive. This doesn’t mean that you won’t benefit from an amp; not only do amps add extra power but they can also change the sound by improving sound stage, separation and depending on the amp add warmth or brightness.

Another benefit of getting a headphone amp is that some of them have EQ settings on them, so you can adjust the amount of bass you want depending on what you’re listening to.

If you have decided to go for a headphone amp you now need to decide which one to go for, there are many to choose from and they go for anything between £20 and £1500. Amps can be split into two main groups, portable and desktop. If you are going for a portable amp then you could go for something like the FiiO E12 which is powerful enough to drive most portable headphones, it is a good size and has a bass boost setting. If you require more power then you could go for the OPPO HA-2 or the Cypher Labs Picollo. Both of these amps can drive most headphones and they will also improve the sound quality, with the HA-2 being slightly warmer than the Picollo. For the harder to drive headphones there is the Cypher Labs Duet. This amp has adjustable gain settings and provides a less distorted, more accurate sound with plenty of power.

If you only use your headphones at home then you should go for a desktop amplifier as they are generally more powerful. There is a much larger range of desktop amplifiers and you really should know what headphone you will be using before choosing the amp, for example if your headphones have a warm/bassy sound then it’s a good idea to go for a brighter/detailed amplifier. This also works the other way around; a warm sounding amp will compliment bright headphones and balance the sound out.

If you have any questions about choosing the right amplifier then give us a call at Hifi Headphones on 01903 768 910 or you can send an email to support@hifiheadphones.co.uk – we will be more than happy to help.

Acoustic Research M2 High Resolution Audio Player – Expert Review

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.

Lotoo PAW 5000 High Resolution Audio Player – Expert Review

Posted on by

Lotoo PAW 5000 Review

Earlier this year we were pleased to announce the new Lotoo PAW Gold player, but now there’s a smaller (and a much lower cost) model from Lotoo called the PAW 5000. At half the size, less than half of the weight and less than a quarter of the price of the PAW Gold model, can this upstart bring home the audio bacon?

Design and appearance

The button arrangement on the front is very similar to the earlier model, and the wheel on the 5000 model enables files, folders and options to be selected. The PAW Gold’s frontage was adorned by a little too much of the blingy stuff by all accounts, so the 5000 has been reined in with just a touch of gold on the power button. Very tasteful.

With handheld devices, the trend seems to be towards touchscreens now. This can give greater functionality and versatility, but buttons do offer a more instant tactile feedback. Also the advantages of a button-operated unit present themselves in winter where the PAW 5000 can be used with gloves on, or with gloves off and cold fingers!

Key Features

The PAW 5000 has more connectivity than the PAW Gold, with an optional SPDIF output for attaching to an exterior DAC. There’s a headphone socket of course, and a line-out socket for external amps. Another welcome option is the ability to work with bluetooth headphones via the bluetooth 4.0 standard so you can enjoy your music wirelessly without the possibility of snags.

Durability & build quality

The PAW 5000 is a lot lighter than the PAW Gold, but still feels solid. Buttons feel well made, and the wheel has a free-flowing quality about it while still feeling sturdy. Unlike the PAW Gold model however, a collision with a tiled floor may result in a dented player, rather than a cracked tile. Although the player has no flex or ‘give’ as it’s squeezed in the hand, a tap on the back cover does betray a slight hollowness.

Sound Quality

(Tested with an Audiofly AF180 IEM with EQ off on the player)

We’re used to using earphones such as the Audiofly AF180 with a Chord Hugo (with a Fiio X3 connected via coaxial) and so were expecting a bit of a drop in quality in terms of sound quality. It’s not that easy though.

With EQ disabled, sound is neutral with a nice depth and breadth – soundstage is as good as headphones will portray. The presentation does not have the precise, clinical edge which some high-end players (such as the AK240) have, but that’s no bad thing. Details are not lost; they are there, but just not pushed at the listener so much.

The Lotoo PAW 5000 is a good match for these earphones; the AF180 earphones cost only a little more (at £369.99) and are well served. The PAW 5000 helps to bring out the best in them, and should the listener wish to have a bit more (or less) edge to the sound, the EQ settings should have something to please. These are much the same as the PAW Gold player, featuring both permanent presets and user configurable presets too.

Pros

Digital output (SPDIF)
Balanced output (2.5mm)
Many EQ presets, also user configurable EQ
Bluetooth 4.0

Cons

No internal memory
Supplied SuperSpeed USB cable is quite short

Summary

The Lotoo PAW 5000 does not require deep pockets; in more ways than one. The sound quality and features found on this device rival much higher priced equivalents offered by other makers, and the diminutive size of the PAW 5000 makes it very convenient to keep as a constant companion for those quiet (or noisy!) moments.

Shure SRH1840 Review – Yes We Shure Can!

Posted on by
Reply

Verdict

Totally immersive – don’t forget your life jacket and emergency flares for when you inevitably get lost in there. It’s unusual for a highly esteemed brand’s flagship headphone such as the Shure SRH1840 to be going for under £500 (particularly headphones as good as this), so take advantage of Shure’s generosity!

Pros

  • Sound Superb
  • Comfort
  • Spares included
  • Removable cable

Cons

  • Some may find headband underpadded

Despite the recent growth of the headphones market and the high standards attained by makers generally, it’s easy to recognise products Shure puts out; always nice to the touch as well as the ear, solidly built and sounding great. So with heavy hearts we find another predictably fantastic pair of headphones for review!

Key Features

Shure has seen fit to include some spare earpads and a spare cable with this model, as it has with the SRH1540. Spending this kind of money on headphones probably gets people searching for extra value and they won’t be disappointed here. Also a storage case is included.

First Impressions

Having not long put down the SRH1540, it was surprising how light the SRH1840 still felt. These headphones are almost not even there, particularly when worn. Some would prefer more padding on the headband, but the negligible weight is borne mostly by the earpads.

Sound Quality

Warm without being bassy, crisp without being strident – Shure has really done a good job here. Things can get a little harsh with a raft of flutes playing, but that’s the nature of the sound which the SRH1840 brings out faithfully. Also an amp will be an advantage – the impedance and sensitivity of the SRH1840 is not suited to being used straight out of a portable player or phone. My Fiio X3 can power them but seem as if it is straining a bit. An E12 gave a more relaxed presentation, and the bass boost was not lost on the SRH1840, giving some added weight to proceedings. There may be a bit of a bump on the SRH1840 at the top and bottom ends of the range, but midrange is still fully represented.

Summary

Close to perfect. For those who want just a little more detail without spilling over into strident territory the Shure SRH1840 is certainly worth considering. Together with the modest price and incredible comfort, the SRH1840 is a flagship model indeed!

Score 9.5/10

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

Posted on by
1

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 by
Reply

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

Chord Cable Interconnects – To The Test

Posted on by
Reply

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.

Do I Need A Headphone Amp?

What’s the point of a headphone amplifier?

Not sure whether to buy a headphone amplifier? This article will inform you of the benefits of adding an amplifier to your existing setup, or buying an amplifier with your new headphones.

When you’re buying some new headphones it’s always good to think about what your source will be; whether it’s an iPhone, Laptop, DAP (Digital Audio Player), your home HiFi or a bit of everything, figure out which has the lowest output and if it can drive your chosen headphone. So if you use a mobile phone as your main source and you’ve decided on some Earsonics SM64 earphones which are very hard to drive, you will need a headphone amp to add some extra power so you can get the most from your new purchase.

There are plenty of headphones designed to be used with mobile phones and other low powered portable devices; these headphones generally have low impedance (up to 32ohm) and high sensitivity (95db and over) so they are very easy to drive. This doesn’t mean that you won’t benefit from an amp; not only do amps add extra power but they can also change the sound by improving sound stage, separation and depending on the amp add warmth or brightness.

Another benefit of getting a headphone amp is that some of them have EQ settings on them, so you can adjust the amount of bass you want depending on what you’re listening to.

If you have decided to go for a headphone amp you now need to decide which one to go for, there are many to choose from and they go for anything between £20 and £1500. Amps can be split into two main groups, portable and desktop. If you are going for a portable amp then you could go for something like the FiiO E11 which is powerful enough to drive most portable headphones, it is a good size and has two EQ settings. If you require more power then you could go for the FiiO E12 or the Just Audio UHA-120. Both of these amps can drive most headphones and they will also improve the sound quality, with the Just Audio being slightly warmer than the E12. For the harder to drive headphones there is the Just Audio AHA-120. This amp has adjustable gain settings and is class A, this provides a less distorted, more accurate sound.

If you only use your headphones at home then you should go for a desktop amplifier as they are generally more powerful. There is a much larger range of desktop amplifiers and you really should know what headphone you will be using before choosing the amp, for example if your headphones have a warm/bassy sound then it’s a good idea to go for a brighter/detailed amplifier. This also works the other way around; a warm sounding amp will compliment bright headphones and balance the sound out.

Sennheiser’s top of the range headphone-amplifier combination is as pleasing as expected. John had a closer look at the pairing and gave it a thorough listen – without further ado, enjoy our newest video review!

Sennheiser have created the HDVD800 to excel the current levels of audio quality for audiophile listening. As the perfect match for Sennheiser’s audiophile headphones, the HDVD800 delivers a balanced sound image, maximum precision and impressive tonal spatiality with perfect conversion of digital to analogue signals.

The HDVD800 connects with all digital sources and is equipped with a high-quality Burr-Brown digital to analogue converter that modifies audio signals with superior resolution. Digital sources can be connected to the rear of the unit via an XLR input, optical and coaxial digital inputs or USB. Further to the symmetrical inputs, the asymmetrical input socket of the HDVD800 is able to balance incoming signals before further processing takes place.

Both the housing and potentiometer control, as well as the rotary switch for source selection, are made of anodised aluminium, while the front panel and other controls are machined from solid metal. Visible through the glass panel of the HDVD800 is the cooling element, the audio relay and countless resistors for the amplifier giving the user the feeling of being part of the amplification process.

This high-end amplifier fits in perfectly and delivers superior acoustic performance when paired with any of Sennheiser’s audiophile headphones.

The ultimate in audiophile sound.

Dispensing Audio Justice – Just Audio uHA-120DS

Just Audio‘s range of headphone amps make a nice change from the sleek appearances of similar offerings from larger competitors. This may sound like a backhanded dig at the styling of this range, but not at all. On the contrary, it gives the units a bespoke appearance; one that promises to reform the sound in a no-nonsense, pragmatic way.

The new uHA-120DS also operates as a fantastic DAC and the improvement over my little Behringer UCA202 USB soundcard was plain, even when using passive loudspeakers.

There is the option to switch between battery power and USB power if used as a DAC, and between ‘Normal’ and ‘Fast’ charging depending on which USB standard is possible with your set up. Installation is easy, I tried the 120DS with Windows 7 and good old XP and both were fine; the PC recognised the unit and had it working with no extra work necessary, only to chage the settings to make the unit the PC’s default audio output. I’m told that there is a similarly smooth experience waiting for mac users too.

I tested the unit against a FiiO E07K to see how the audio from these two amps/DACs compared. For this cross examination I used the excellent Phonak Audeo PFE 232 earphones; to let no nuance escape the jury’s attention. The FiiO sounded a little brighter on first impressions, but on closer inspection there appeared to be either a small boost to higher frequencies with the Fiio, or a smoother presentation with the uHA120DS.

The Just Audio unit came across as being more relaxed; it didn’t break a sweat under the pressure and gave some very convincing testimony. Perhaps given that the uHA120DS is 4 times the cost of the FiiO, there’s no surprise here. You always get what you pay for when it comes to witnesses.

An absolute discharge is called for in this case, which is a relatively rare event. The battery can last anywhere up to 40 hours, depending on which headphones are used with the device and the amplification used, etc.

Before you ask, there is no ‘dock’ for an iPod however. Take him down!
