What customers say about "Key Specs"

Astell&Kern AK 70 MkII High-End Player with Integrated Powerful Amplifier DSD Native Black

Great UI and sound from wired headphones, on that side AK70 does it’s job perfectly.
Excellent product, great sound through both high quality in-ears and over ear headphones.
It has 64 GB of internal memory that is enough for the first time not to buy a memory card. Wow.
The screen is easy to view and very effective and enjoyable.
User interface as usual with Android based systems the user interface feels somewhat clunky and not entirely stable.

What customers say about "Size & Weight"

Astell&Kern AK 70 MkII High-End Player with Integrated Powerful Amplifier DSD Native Black

The AK70MKII is slightly bigger so it feels better in my hand, the dual DACs add better depth and separation to the music and the bigger battery means I can listen for longer.
Just the right size (similar to iPod classic but a touch narrower and deeper), excellent build quality.
All in all, fantastic player in a small footprint which makes it easy for me to carry around on the tube! Highly Recommended.
A player that will be next to each of your trips due to its compact size.
I really like its size. It lies comfortably in my hand and also looks beautiful.

What customers say about "Features"

Astell&Kern AK 70 MkII High-End Player with Integrated Powerful Amplifier DSD Native Black

I have listened to numerous recordings from MP3 to studio master 24bit files and all are reproduced superbly through my usual Etymotic ear phones.
Networked works well. I can access files on the AK70 for playback on my main hi-fi system.
Detail is superb and all areas of sound, bass, midrange and treble, are solid and involving. Soundstage is exspnasive and awesome.
Shamefully, this one is too sharp in the upper frequencies, and accordingly has been sent back.
There is no equaliser that can be customised even though the instructions say there is.

What customers say about "Power"

Astell&Kern AK 70 MkII High-End Player with Integrated Powerful Amplifier DSD Native Black

Sounds great, average battery life, competition stiff at this price point.
Built quality, battery life, sound output is probably the best on the market for that price range.
I have enough charge for the whole day of use. Highly recommend.
A great player that lasts all day with you. The sound is amazing.
Battery only last 6 to 8 hours. Music gets lost when your attention is elsewhere. So not really designed to attract attention as a portable should.
