Astell&Kern AK240 – Expert Review

Astell&Kern AK240 HIfiheadphones

Pros

  • Fashionable touchscreen operation
  • Very solid build quality
  • Large 256Gb internal memory
  • Audiophile grade sound
  • Very connectable
  • Charges by USB
  • Supplied with high quality leather case

Cons

  • Volume control feels a bit flimsy
  • Power up a bit slow

Verdict

A uniquely designed high-resolution player that is generally well made. Sound quality is is up there with the best digital audio players available and has plenty of connectivity options. Some may find the touchscreen a little old fashioned with a relatively slow response time.

Intro

Astell&Kern needs no introduction as a leading brand of high end portable players, and many fans of top-notch sound quality hold the players they produce in high esteem. So their flagship model, the AK240, has its work cut out!

Key Features

The AK240’s touchscreen encompasses a lot of possibilities and intuitive control features; for example it’s very simple to fast forward through a long track as the position marker can be dragged as fast as the user’s finger is moved. Also, changing volume can be done on the screen; but beware if you have sensitive IEM’s! Luckily there’s a dedicated volume control for those without steady hands.

Connectability is there in spades; the AK240 has a bluetooth capability so suitable wireless headphones can be used with it, any compromise with sound quality will have to be weighed up with the convenience that bluetooth headphones provide. Also Wi-Fi is featured so music can be sent streaming around the house, and files/folders can be read from and added wirelessly.

Also, the AK240 has an optical output which allows the user to send music data to an external DAC if preferred, and a balanced output for those who will accept no compromise where sound quality is concerned.

 

First Impressions

The Astell&Kern AK240 player looks like a piece of modern architecture at first glance; the screen is partly framed by two very angular bevelled edges which act like an optical illusion of some kind. This does lead to some problems gripping the AK240; care is needed when picking the player up off a flat surface as the right-hand side is relatively thin. The AK240 is supplied along with a high quality leather case, which will go some way to improving this.

Once safely in one hand, the user will likely need the other hand to operate the AK240 as the touchscreen control demands accurate direction by an attentive finger, also the touchscreen requires the user to see what is displayed in order to operate the unit. Volume can be altered by the dedicated control on the right side; this does feel a bit flimsy but offers no trouble during operation.

Once a track is playing, the cover art (if available) is displayed along with the usual artist/track information making a pleasing visual display, until of course the auto-hold feature renders the screen blank. A quick press of the power button brings the display and control capabilities back of course, and this feature can be configured as the user sees fit.

The AK240 does take a couple of minutes to read the contents of a freshly inserted Micro SD card before continuing, so if you’re chopping and changing with multiple cards don’t expect to be listening to your music immediately.

For the asking price, there are going to be some very demanding end-users with some very exacting requirements. We’re happy to say that the AK240 addresses these with aplomb. Any drawbacks mentioned are relatively minor and we mention these as we understand the stringent expectations prospective users may have at this high-end level and price point.

It would have been preferable to have a player which feels as good as it looks. Certainly the AK240 is visually striking but beauty is only skin deep. The attractive sheen may wear thin as the player is used on a day-to-day basis, due to the way it feels in the hand; there is an unyielding quality about it which may alienate some after a while.

Sound Quality

The Audiofly AF180 was used for the listening test, along with a Beyerdynamic T1 to test for available power.

Needless to say, the sound quality is stunning. But in order to gain a bit of perspective we put the AK240 up against a similar high-end player, the Lotoo PAW Gold. The general concensus is that the Astell&Kern AK240 reaches a bit lower and provides a little more ‘rumble’ in the bass department, while the Lotoo PAW Gold has a bit more up top making the tape hiss on Queen’s ‘Another One Bites The Dust’ a bit more apparent.

The feeling was that the AK240 gives a little more atmosphere and space; it’s a very natural and effortless sound. Acoustic and classical tracks are very immersive, with separation which is second to none in terms of portable players. Things seem a little more reined in and controlled when dealing with dynamically compressed pop music. These differences are very subtle of course, and are only mentioned to give the reader a more meaningful explanation of the player’s capabilities rather than those of the headphones used.

Power is plentiful too – the Beyerdynamic T1 was driven very well, the only time more headroom was required was with quieter classical passages with of course no dynamic compression applied within the production.

 

Summary

In terms of sound and functionality, it may come as no surprise that this is perhaps the best player available. The connectivity and versatility really make the Astell&Kern AK240 special; however not everybody likes a touchscreen and this may dampen the enthusiasm of some. Operating the unit may require it to be drawn out of the pocket, and any accidental swipes may lead to some frustrating moments.
Score 9.0

Lotoo PAW Gold Player – Expert Review

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

Lotoo PAW Gold Player Review – Reference Level Audio Player

Pros

  • Quick response to button pushes
  • Solid, sturdy build
  • Navigation simple and quick
  • Huge card capacity
  • Fast power up
  • Recessed yet accessible volume control
  • Great value for money

Cons

  • Golden volume and navigation controls may be on the blingy side for some
  • No digital outputs
  • Charges via mains adapter/wall wart only – not USB
  • Screen seems small amongst those of other DAPs

Verdict

A very capable and well-built unit, the Lotoo PAW Gold Player looks and feels as good as it sounds. The array of buttons make navigation a breeze and they’re all easy to get to. The unit feels right at home in the palm of the hand, and is easy to operate – even in the pocket once the control layout is familiar. It scored a hit with everyone here who tried it, and together with its future-proof SD card capabilities it looks like it is going to be some tough competition for other high end portables out there.

Intro

Joining the ranks of companies entering the portable audio fray with a high-end audio player is a company called Lotoo (pronounced low-to) with the PAW Gold. With audio quality that matches the Astell&Kern AK240 player and a price which is a whole lot lower, you may not need to win the lotto to enjoy this player!

Key Features

The most striking thing about the PAW Gold other than the large golden Mayan-style control on the front is the obvious button-focused control method which is a contrast to the AK240’s touchscreen. And it’s horses for courses; many people love gadgets with touchscreen operation and many people prefer buttons, these offer instant feedback as the user knows that a button has been pushed, and instant access to menus such as the player’s start screen or EQ settings is certainly a bonus.

Lotoo have gone for simplicity in terms of outputs and connectivity; the PAW Gold offers both a headphone output and a 3.5mm line-out. Sound quality is described below, but it’s unlikely that any external DAC is required to be used with the PAW Gold, also this DAP packs a real punch in terms of power so external amping is unlikely to be needed if the user is on the move. Line-out is a nice extra though if connecting to full-size amp and loudspeaker system.

The PAW Gold can accept some giant capacity cards – it’s designed to work with SD cards, but can of course be used with Micro SD cards by means of an adapter. So up-to-date is the Lotoo PAW Gold, the maximum capacity card does not yet exist! This may be a window into the future as the maker has seen fit to add compatibility for 2TB (2 Terabyte) SD cards. The largest sized SD Card available as of this time is 512Gb, so there’s a clue!

The volume control is accessible but nicely recessed at the same time. No need to be nervous when donning sensitive IEMs for example. It has a nice feel to it, neither too stiff nor too loose.

 

First Impressions

The size of the PAW Gold is noticeable when we’re used to ultra-skinny items such as modern phones and media players, but it feels like a solid piece of kit, much like something from the realm of professional audio. Not surprising, as the maker is well known for manufacturing innards for other brands’ high quality audio gadgets.

It feels great in the hand (left or right) and all buttons are easy to reach with the thumb. The screen is comparatively small but this is designed to be listened to after all. On-screen information consists of file audio quality details and track/artist details, with a large stereo level meter.

A moment of confusion was when the ‘key lock’ switch had been operated; this was not immediately obvious to me when I tried to operate the unit. The display showed the ‘power down’ screen leading me to think the battery was low, but a colleague pointed out that the key lock feature had been enabled. Perhaps a future firmware update might address this.

Sound Quality

As may be expected for a player at this price point, sound quality is top notch and can only be compared to similar bits of kit to give any meaningful impression, such as the Astell&Kern AK240. The PAW Gold resolves very well, perhaps a tiny bit better than the AK240, but the AK240 gives a better sense of atmosphere. Much like the difference between valve and solid state amps, although much more subtle.

The audio was tried with the in-ear Audiofly AF180, as well as with full-size headphones such as the Beyerdynamic T1. The PAW Gold gave a vibrant and immersive presentation, and with genres such as classical music, a wonderful richness. Timbre/harmonics are brought out and separation is very realistic with an excellent soundstage.

The amp was certainly put to the test; as well as the Audiofly AF180 IEMs which were used for the critical listening tests, a pair of power-hungry Beyerdynamic T1s were plugged in. The PAW Gold has 2 levels of gain and on the louder setting the T1 was powered very nicely. Only during the quieter parts of dynamically uncompressed classical tracks was any extra headroom called for; it’s safe to say that for any headphones under 600 ohms and with sensitivity equal to or greater than the T1’s 102dB this will not be an issue.

Summary

With portable players, many factors come in to play as the unit is picked up, put down and carried around many times per day; the sound is as important as what the unit is to live with and operate on a day-to-day basis. The PAW Gold certainly passes both tests as, despite its solid chunkiness, it becomes like an old friend very quickly. Once the button layout becomes familiar, the unit can be operated (such as track skip) in the pocket without needing to take it out, and the unit just feels good in the hand.
