Big source improvement using CD player


I borrowed a friend's esoteric dv50s CD player.  I could not believe the difference between it and streaming Spotify premium.  I am now in the market for a CD player.  One thing, the esoteric does not play DVD-R.  Can anyone recommend a comparable CD player in the used market that does? I'm looking in the $800 - $1500 range.

My two cents, you learned the wrong conclusion.  You are using a compressed streaming source, and who-knows-what DAC (you didn't say). Compared it to a high end CD player.
In general, all else equal,i prefer playing FLAC/ALAC files or streaming them (or HD of course) to playing plastic CDs.  And there are reasons this might be true.
Slow down, experiment, learn.
How do you get the Oppo BD 105 to stream Tidal?
You can use a Upnp control point that has access to Tidal (I use the Bubbleupnp app for that, select Tidal as library). The Oppo 105 acts as a Upnp renderer, that you can select in Bubbleupnp and stream music to it.
You might want to look at the Oppo products. The udp 205 has a high quality Sabre dac.
