In comparison to my vinyl, CDs, files and streaming sounds flat and unremarkable.
Not at all surprising given you’re using a computer as a streaming source and a sterile, budget DAC. You need both a new DAC and a dedicated streamer to really up your game, and continuing to use your PC for streaming is a non starter because it’s an absolutely awful streaming source. I’d recommend the Denafrips Pontus ll DAC and the Innuos Pulse Mini streamer as the former is very natural sounding and the latter is a good streamer (and worlds better than your PC) and comes with an app that’s excellent both for sonics and ease of use. Just my $0.02 FWIW, and best of luck.
