The AK70's DAC, based on market-proven CS4398 chips of Cirrus Logic, has been used for years in Hi-Fi audios and the second-generation Astell&Kern devices.

The AK70 plays back 24bit 192kHz signals into bit-to-bit type.

32bit audio is downsampled using a sample-rate converter. In addition, DSD 64/128 can be played back through conversion to PCM.

The AK70 supports the 2.5-mm 4-pole balanced output (2.3 Vrms) that has been in use since the second generation of the Astell&Kern players.

Unlike the unbalanced type, the balanced output type is capable of removing noise (common mode noise) that can occur in “signal + inverting amplifier signal” and has the strength of increasing output due to its double transmitting signals.

The AK70 can be used with a variety of balanced earphones and headphones made for Astell&Kern. It can also support the 3.5-mm 3-pole unbalanced output (2.3 Vrms), with compatibility with a variety of Hi-Fi earphones and headphones.

The AK70 can allow users to rip CDs with ease by linking with the AK CD-RIPPER.

By inheriting from the AK500N, it supports the CD track error correction feature and the meta data (ID3TAG) auto input feature using Gracenote's database without any change.
