Roon vs Qobuz Connect

@dwette got it. The Weiss 501-mk2 is fully network enabled and talks directly to Roon core. I use the Moon 891 which is a streamer-dac and hence the choice arises between Qobuz via Roon or just Qobuz. 

@debrajray I previously had a Naim NDX2 streamer/DAC. I tried QC with that. It sounded slightly better, but I really don't like the user experience of Qobuz' controller software. I mostly play jazz and classical, and am more album than playlist oriented. I returned to Roon for it's superior user experience and features in that regard.

But it's moot for me now. I have no device for my main system that supports QC.

@dwette exactly, I dislike the Qobuz controller software quite apart from its inability to aggregate (which I don’t blame it for). Roon is superior in all these aspects — and I have one of those lifetime subscriptions from some years ago. That’s why it irks me to sacrifice on sq, which is discernible to my ears. 

I have compared both as can use both with my SOTM streamer and at first QC sounded better but then became fatiquing over time.  I think it plays louder giving the impression of more detail but Roon have same detail, soundstage etc but  smoother.  Then I discovered DSD256 upscaling/conversion with Roon and that’s where I landed as completely happy with the sound with my T+A DAC 200 with native DSD conversion.  Running Roon server on my PC was a pain until I bought a NUC to run Roon server 24/7.   Just my subjective experience with my system.

There is little doubt that QC sounds significantly better than Roon streaming Qobuz
 

I don’t agree with this. These types of blanket statements should be avoided - there are many variables at play.
In my system Roon streaming Qobuz and Tidal sounds better than Qobuz or Tidal connect.
