I use my Oppo 203 as a transport (and for bluray/4k movies)into an external DAC, and it performs flawlessly playing CDs. While I'm sure there are better transports out there, the 203 does well. That said, the prices for Oppo players are insanely high (especially unboxed ones!), and you could get a good amount of money for it to spend on something else.
Use or sell/replace Oppo UDP-203?
I bought and intended to unbox a UDP-203 in the summer of 2017 and then Hurricane Harvey happened. We have been treading water since then, but are about to move back into a permanent (larger) residence, where I will be able to again set up a AV area. But, we never really had a DVD/BR collection, the world has changed, and I don't really see us again using a player for physical video discs. On the other hand, I have a nice CD collection and foresee upgraded streaming audio in the future. Initially, listening (and theater) will be via a Cambridge Audio CRX120, but I am open to adding an integrated amp and DAC/streaming device for 2 channel audio. I should probably add that I am old, getting lazy, and the hearing isn't what it used to be - I can foresee eventually moving on from CDs and just streaming (especially if Spotify would ever get their high-res act together).
So, what to do? Should I unbox the new Oppo and use it for CDs, or better to sell it for its current inflated value, and use the money for a CD player and/or streaming device? If the latter, equipment suggestions are appreciated. TIA.
