I guess the value depends on how the headphone amplifier section has been implemented, the old S6 used dual TPA6120, so balanced output impedance was about 20 ohm.

The fact that aune doesn't give any data on output impedance for the unit and no internal pictures are yet available makes me think that the HP output circuitry is similar to the S6, which IMO would be a bit dissapointing.

Where did you get the information from? I don't think s6 has tpa6120.

I thought the same, but it seems it is, and internet reviews indicate poor performance (fr.variations and higher distortion) with low impedance loads and at least the single ended output.

The new model price is reasonable since the AK4497 chip is expensive, but the question mark is how it perfoms as a HP amp.

It's a pity that many otherwise decent AIO designs fail at providing a no compromise HP output, JDS labs and others have shown that great performance can be achieved at a low price point.

It's surely funny that their old an low end products perform better. And aune came from hifidiy (like diyaudio but Chinese). You can search for artemis amplifier or their s7. They use opamps in parallel like massively parallel structure but..... Anyway.
