I also have Qobuz-->Bryston Pi. I also think spinning a CD on a BOT-1or playing files sound a tiny bit better and I mean tiny. Upgrading to a mesh network and having the Pi connected directly to a node and upgrading my cable reduced the margin even more. But not enough to dump a wad of cash on an upgraded streamer. The last move I made was putting a ROON core on an SGC ST and switching the Pi to an endpoint. Proly sit at this level for a while as it sounds really close to files and my Rega P6/Ania Pro. Nothing matches ROON for library management that I have seen. The Radio Paradise app for sure sounds better on the Pi than Roon and I switch back to Pi/MPD when critically listening to that source but otherwise I am all ROON now.
If my dealer ever gets a MOON Mind 2 in I might consider doing a head to head with the Pi. Or picking up a Used Bryston BDP-3. But the BDP-3 is totally over kill for just tapping a service or Roon Endpoint.
