Term "Streaming" used to be dedicated to music you don't own.
I use computer as server for the the music playback. IMHO it can sound better than CD/Transport. Transports operate in real time being able to read particular sector only once and in case of failure have to derive missing data from the error correction or to interpolate. Cheap computer drive ripping CD can read the same sector hundreds of times util proper checksum is obtained and this can also be verified by the checksum of whole CD. I transfer this bit-perfect data over wi-fi, making anything on computer side (speed, amount of RAM, playback program) irrelevant, since only 100% bit perfect data gets to the other side of WiFi bridge. Up to this point it is only bit-perfect data (no timing involved). What happens next, how this data is delivered to DAC decides upon sound quality. It can be better or it can be worse than CD/Transport, but it is cheaper and more convenient. I still have physical CDs because I like tangible media and because it is required by RIAA copyright rules. The fact that I can easily make multiple backups gives me sense of security and longevity of my music.
As for streaming services like Tidal - I tend to be old fashioned, but who knows - using server also sounded foreign to me at first.
