Personally I suspect it is the hard filtering needed to maintain the audio bandwidth but reject the Nyquist frequency and beyond in pcm formats that make listening to pcm less pleasurable than DSD. DSD filtering is more noise shaping so in band phase and group delay distortions are less obtrusive.

Another possibility is that the on-the-fly DSD to PCM conversion algorithms used by ffmpeg aren't "state of the art" compared with other converters such as the Weiss Saracon offline conversion software.

Also, I have read that a perfect lossless conversion of DSD64 to PCM would produce a 64-bit 352.8 KHz PCM file. Downsampling this to 24/176 will invevitably degrade sound quality.

Hi Simon
Thanks for this information
If you know, when setting dopwav as the output, what makes the output setting to wav 24/176? (Seen on my control point)
Assuming my streamer could accept 32/384, would it be possible to set output to wav32;352 to get as close as possible to the original DSD source?
Im interested to get as close as possible for best sound quality.
Many thanks in advance
Anton

Anton, my understanding is that dopwav is not like transcoding from one format to another but a packaging format to enable a bitstream to be sent as pcm over ethernet. The streamer reinstates the bitstream so you should have full resolution of the DSD source.
