Ripped CDs in WAV sound better than streaming and FLAC. If you have a highly resolving system you will hear it in the texture and timbre. Also streaming brings in a whole other mess of issues such as internet noise etc.
Ripped CDs onto an internal SSD or USB plugged into a streamer/renderer will give the best results except for actual CD spinning but that difference IMHO is just a fraction of difference, the difference between ripped CDs and streaming is much bigger. Most people won’t have a problem with ripped CDs because the convenience is immense.
Of course if you don’t have an extensive CD collection there’s downloads which are expensive or you have to use streaming.
