Explanation of the report from Astell&Kern AK320


AK320 plays an audio stream of 44.1 kHz on the DAC is not direct. AK320 uses resampling. This is evidenced by the aliasing graph.
AK320 have AK4490 DAC. AK4490 DAC have five presets digital filter. it's Sharp, Slow, Short Sharp, Short Slow and Super Slow. Aliasing graph from AK320 dues not similar to them presets.

AK320 have a similar graph as KANN

if KANN connect to USB (as USB-DAC) digital filter works default preset Short Sharp. SRC off from Astell&Kern.



SRC does not off in AK320 with connect to USB.

Quality of SRC is good. SRC have not visible distortions. Probably, sound stream 44.1 kHz upsample to 174 kHz. This algorithm replace path algorithm of digital filter from DAC.



if external dac connect to spdif to AK320, soundstream out is correct without SRC.

Measurements of Astell&Kern AK320 Balanced were carried out by Roman Kuznetsov on the hardware-software complex RAA.

The Astell&Kern AK320 Balanced test was conducted as a black box test, without regard to cost and prestige. This is the basic principle for making measurements, measurement reports and developing tests in RAA.

I believe that it is important to do not make an absolute assessment of the device, but an aggregate assessment when working together with a headphones and taking into account external factors. This allows you to effectively reveal the potential of the entire set of devices or to make a more optimal choice of components.
