I've been reading along for quite a while and now, after SW2beta, finally bought it.
What I see and hear is very likeable. The reported DSD hiss (which held me back) seems to be remedied, at least I can't hear any. Sounds great wired.
The AP80 would frequently be used with BT(aptx) too, but there is always the infamous pop/crackle between the tracks as in the old days of digital... I listen a lot to opera seria, so that's a nogo and would mean returning.
It was quite unexpected, Hiby Android App does deliver smooth, undisturbed BT on my phone, as does my old BB Z10 stock player. Crossfade, gapless didn't help. I'm listening BT on B&W P7 BT, also tested with wife's Sennheiser HD 4.5, Aptx or SBC, dsf, flac, mp3... no chance.
Is there anything I missed out/could be tried? I'd really prefer to keep the player. Or is it just the way it is?
