Cheers. With the Onkyo I already have that option enabled and with the Herus it plays DoP straight through - i.e. DSD Native. If I replace the Herus with the either Cypherlab DAC-Amp, it'll fall back to PCM even with DoP mode. As for UAPP, I'm not familiar with DoPFLAC so I'll have to read up more about that next. I'd guess the trial version would work with DoPFLAC too, then I may be able to test UAPP on my Galaxy J -> Invicta which is the only way for me to confirm if it's actually decoding & playing DoPFLAC as DSD native. Edit: In other words if Onkyo, which is capable of playing DSD Native on some DACs but falls back to PCM conversion the Cypherlabs DAC, I'm wondering if UAPP would be the same on Cypherlabs DAC too.
