Hello,
I think everyone should have a nice DAC and streamer. Great way to listen to an absurd amount of great music. If you do have a nice DAC then adding a Cambridge CD transport for $600-$700 is not a big deal. I do have some titles that are not streamed or not streaming on the services I use. Also, There are different recordings or presses if you like of the same album. I just ordered a used 20th anniversary edition of Pink Floyd DSOTM. I heard it is supposed to be good. Just another way to enjoy the music that might not be out there. Maybe your Cd/ Setup sounds different because of the player or the cables that are connected. I have a really nice DAC/ Streamer but that doesn’t let me play Tommy Who or Paul Simon in 5 channel surround off of the SACD player. Just another avenue to enjoy this great hobby.
