Does Roon have better or worse sound quality than dCS Mosaic

[Anupc (Anup)]

@liquan

but the Roon and Mosaic do use different ways to stream the music, which are UPNP with Minimsever for Mosaic and RAAT protocal for Roon. I think we have ground to suspect that there may be a difference.

Thats exactly what I thought too. Until I tested it and the unwrapped bit-streams were literally identical.

@liquan

In addition, a bit-for-bit identical playback doesn’t alwasy mean the same sound quality, otherwise we don’t need to worry about the usb cable and ethernet cable.

If you’re implying Jitter as the factor that makes otherwise identical bit-streams different, it doesn’t apply in the case Roon/UPnP as these are error-corrected and buffered streams. I can capture the bit-streams on a PCM recorder and the files are literally identical

By the way, here’s dCS’ view;

Roon Setups with Rossini

Yes. There should be no difference in audio performance between Roon and UPnP. There are a lot of reports of one being better than the other, but I keep a close eye on these and there is an equal split in numbers between Roon better and UPnP better as well as a larger number of reports of hearing no difference at all. This tells me that statistically there is no real difference in absolute performance and it only comes down to the preference of the listener. File playback sources via other inpu…
