“A&K’s new entry-level hi-res music player, the AK70 had to be better than the last. And better it is. “ ‘What Hi-Fi? award winner 2016’. 5-star review.

High Resolution sound – the highest ever for music on the go
High Resolution Audio files take music to the next level. High Resolution Audio provides music files in 24 bit/96kHz or 24 bit/192kHz formats. Digital music files at this level provide a much more detailed and smoother sound than typical CD (16 bit/44.1kHz) files. The difference between HD (High Definition) music and typical MP3/AAC compressed music files is even greater. HD music offers a deeper and wider sound stage, more precise imaging and, above all, a far greater sense of realism.

A wide choice of music already available
There are many HD Audio recordings already available to download online and you may already have started a collection on your computer or NAS drive. Where the AK70 really scores is being able to take those recordings with you – in the highest quality possible. The AK70 supports a wide range of file formats, including WAV, FLAC, WMA, MP3, OGG, APE(Normal, High, Fast), AAC, ALAC, AIFF, DFF and DSF.

DSD support by conversion
As well as the above formats, the AK70 also supports DSD 64 and 128 formats via conversion. Originally designed for SACD players, DSD (Direct Stream Digital) encoded music files offer the same detailed, transparent sound as other HD file formats. The AK70 uses a powerful processor to convert DSD signals to PCM for superb resolution.

Support for balanced headphones
With its 4-pole headphone socket, the AK70 is ideal for use with balanced headphones. Using a balanced signal between the source and headphones reduces noise and interference and is especially handy on the move.

USB Audio
The AK70 is the first A&K model to support USB audio digital out. You can connect up digital-input portable amps through USB to the AK70, for the purest sound quality. The AK70 can transfer DSD in native through DoP (DSD over PCM). It can also convert DSD into PCM for output for portable amps that do not support DoP.

Astell & Kern CD ripper
Uploading your CDs is easier than ever with the AK70. The AK70 lets you rip CDs with ease by linking with the AK CD-RIPPER. It supports the CD track error correction feature and the meta data (ID3TAG) auto input feature using Gracenote’s database.

Wi-Fi enabled for streaming and updates
A further upgrade over the Jr model is built-in Wi-Fi. This lets you choose the connection that’s best for you. For the fastest and most stable connection to your PC or Mac we’d recommend USB. As a cable-free alternative, choose Wi-Fi for streaming from NAS drives or other DLNA enabled devices such as your laptop.

Pocket a Hi-Res audio bargain, with the Astell & Kern AK70.


There’s no ignoring the price, though – £400 isn’t cheap. If you shop around, you’ll notice that Hi-Res Audio players are no longer a rich man’s game. Sony’s A15 is around £150-200 and the Fiio X-1 costs just £100.

But if you want a great combination of looks and audio, the AK Jr won’t let you down.
