Music pauses when headphones are unplugged. You want setting to turn this off?
Honestly, this is first time I hear about such way of storing DSD files, it might be simple our system is not set up to sort such FLAC files in this way. Can you send me one such files over PM to test?
Re Native transport, it's simply missing in our system for now, since it was showing problems during testing. It can maybe help in theory, in practice it was showing problems.
Also, not sure about what clicks and pops are you talking, we are aware of problem when using USB out, but I think most users are playing DSD 64 DoP just fine.
To the Hi-Res certification, I didn't say the ESS9218p is Hi-Res certified. Just that if you want more detailed info on technical capabilities of amplifier build into ESS SoC, go and ask ESS.
Shanling M0 is certified for Hi-Res certification exactly by the conditions set up by JAS.
