Astell & Kern - AK70 - Digital Audio Player
A new, entry level model to fit above the AK Jr, but below the AK100-II/AK300 models,
64GB of onboard storage, expandable via the microSD card slot.
Featuring the same DAC chip in single configuration that was used on the previous AK100-II and AK120-II models, while still having full support for the AK Connect and CD-Ripper, allowing for great functionality support with most accessories.
It uses the same operating system found in all the higher end models, which is based off Android, allowing full network streaming and server functionality.
This unit also does support DSD 64 & 128, but via DoP (DSD over PCM) which downsamples it through to 192kHz to playback.
While also having the ability to playback 384kHz/32Bit files, but again downsampling them to 192kHz/24Bit.
Now here is a really cool part... the new AK70 supports USB Audio OTG (On-The-Go) which allows to connectivity to USB DAC's!
It also offers 2.3v RMS Output via the 2.5mm Balanced output, which is similar output power to the higher end AK320/AK380 models.
While still offering the 3.5mm output jack with Optical Digital Output.
