What is your streamer? You have a very DAC… and I assume associated system.
I have been streaming with a high end system for four years… and 15 years before that. And I find the sound absolutely consistent. My streamer cashes the data.. so it sounds exactly like the CD and typically sounds better… often because the Qobuz has a high resolution version. But recently I noticed the noise floor is actually lower with streamed files (my Aurrender W20SE streamer operates on battery power for the audio circuits) over CDs.
I’m guessing it is related to the streamer.
