DSD over PCM question - Womaz - 12-Nov-2015
Hi
My Melco can be set up to either of two options depending on the USB-DAC.
PCM over DSD
Convert to PCM
Which one should I use on the 200?
RE: DSD over PCM question - rwjr44 - 12-Nov-2015
I would suggest the DSD over PCM (DoP) because it MAY sound better. Why? The Devialet converts (someone correct me if I am wrong) everything to 40 bit 384 kHz for processing. If you set the Melco to convert DSD to PCM, you are adding another processing step which may not be transparent.

Brilliant thank you, thats what i have it set at now.

i dont know if we have the full story on what upsampling is done or when it is done.
you should try both! as soon as hq player is integrated into roon im going to spend a lot of time figuring out the best sampling rates

I understand your desire to experiment, I do a lot of experimenting myself. The point is that whatever we do before it enters a Devialet, the Devialet will convert that to 40/384. Perhaps there is some synergistic combination that will make the Devialet sing?

I will categorically state that I have no desire or intention to experiment......none whatsoever!!
RE: DSD over PCM question - completeluxury - 13-Nov-2015
are you sure about the 40/384 though?
the 2 DAC's that it uses per channel are 24/192 each so wouldnt it convert it to 24/384?
RE: DSD over PCM question - Antoine - 13-Nov-2015
There's one DAC per channel. We already discussed this in a topic you yourself started...

RE: DSD over PCM question - completeluxury - 15-Nov-2015
haha sorry my bad. i meant basically if it uses 24/192 per channel, why would the output be 40/384 instead of 24/384

Completeluxury, I know it's not been integrated long, but did you happen to invest any time here, and if so, could you share in an HQPlayer thread perhaps?
