I see. I’m not so sure that relates to what I was testing. I compared the same tracks from Roon, where one is stored on the Roon server’s filesystem (as a CD I ripped or a 24-bit file I purchased and downloaded) vs streaming the same thing from Qobuz, but still using Roon. In both cases my Roon server is a dedicated appliance (i.e. Intel NUC running ROCK).
When I had my previous streamer I compared QC vs using Qobuz via Roon. I thought the QC stream was somewhat (but not significantly) better, but not better enough to suffer the inferior user experience using Qobuz’ own UI. I think I’ve noted that above already. I can’t use QC now anyway,
It stands to reason that QC might sound better, since the stream goes from Qobuz servers directly to the QC endpoint, bypassing any other servers (like Roon).
