If you are a real music fanatic CDs and ripped CDs are the best option because for some albums I have ten or more different remastered versions of the original plus loads of bootlegs which aren't available on streaming services. I know it's completely anal but that's my thing.
CD transport vs.streaming
Many have stated on this forum that the SQ from their CDs is superior to the sound from streaming sources. Others have said the opposite. Weirdly, in side by side identical tracks the sound from my Cyrus CDt sounds identical to my Cambridge CXN v2 streamer. I wonder if anyone else has this experience.
