Best upgrade for cd player?

Thanks to speakermaster and dinov. Helpful!

Get a good DAC.  That’ll give you more of an improvement than pumping more $ into an Oppo that’s out of business

+1 get a good new school R2R discrete dac with volume, and go direct to poweramp/s

Cheers George

+1 in_shore. Computer/server audio surpasses sonically my CD transport (Teac/Esoteric P1). Having my CD collection on a hard drive now, as well as streaming Tidal via an I Pad is just the icing on the cake. Good listening!

@jafant . If I had funds would buy reference dac, likely Berkeley.  Accident/medical expenses killed that possibilty. Off hand answers to simply go out and " buy reference" are a bit difficult for me to appreciate; plus they are not really on topic. Are you becoming a little cynical? :)

Not at all. I still believe in the CD/SACD spinner. That is all.Take it or leave it.
Happy Listening!
