@soix have you considered ripping those to a hard drive or NAS that you can locally stream? I find this better sounding than most transports. Just use a laptop and drive, good software like XLD rip them once and then play those CDs via network using your streaming software...
I have 1000s of soundboard concert recordings that aren't on the streaming services, so this is an important part of my streaming setup and many here do similar for various reasons. Cheers,
