I have both an SACD/CD transport and Roon Nucleus Plus streaming server and I'd say, in terms of SQ it might be a "toss up". They both are connected to the same DAC. One thing that might be a plus for streaming is that, sometimes the CD I own is from an older master and my Qobuz version is more recently mastered and sounds just a bit better...probably being that it was mastered on newer, better equipment.
