@audphile1 yes, good point; thanks. I have actually run that experiment using Minimserver to send local files to Mind, but didn't bring it up here as it was specific to Moon/Mind. I did it now again. I still hear a difference which suggests something intrinsic to Roon overhead rather than having a local server in between.
The difference to me seems to be stronger when comparing Roon and QC directly. But here my hearing could be failing me... I give up! Look: there's no day and night stuff going on. So It's back to good old Roon, I guess.
@rivinyl for what it's worth...
