quality of the original recording overwhelms any minor (i mean very minor) differences in well implemented cd vs streamed music quality
streamed music sounding absolutely tip top quality takes some work and expense to achieve -- some are up for that, other not, but it can absolutely be achieved, as many of us have done it
cd’s sound great too, streaming just as good -- cd players have their own output stages, can have their own sound signatures, as do dacs... so it all depends... hi res streamed through tidal or qobuz is truly excellent - bear in mind cdp's play redbook 98% of the time
my cd front end -- 1) vsei level 6 sony scd-1 2) modwright marantz sa 8005 with tube output and rectification
streaming -- i7 roon core, uptone ether-regen, sonore optical rendu, dacs: msb analog w pb / bricasti m1 mdx / weiss 501
