I have so far doubted that the delta between the sound quality from my streamer/server and that provided by a transport playing physical CDs would be large enough to outweigh the convenience of streaming, at least for me.
If you really enjoy streaming music and it’s your predominant listening choice, I’d recommend that you just stick with it. On the other hand it you genuinely appreciate CD ownership,handling interaction and listening, then pursue a high quality dedicated CD transport. The best you can afford.
Redbook 16/44 can be/is absolutely superb sounding if a higher tier DAC and higher tier transport are carefully selected and paired. This has been my outcome.
