I would keep one SACD/CD player active in the system, remember to use it occasionally to keep it’s lubrication/moving parts from becoming problematic from disuse.
I did LP’s exclusively for over a year, then I bought an Oppo 105, and re-discovered many great CDs.
Compared prior player to Oppo. It too sounded amazing. Kept it, prefer it’s smaller size, features and remote, sold the Oppo. I don’t stream.
I realized, the CD’s sound amazing, better than ever, because of all the other improvements I made:
new power filtering
new 6 nines copper: speaker connectors/silver solder; speaker cables; spades; interconnects with locking rca connectors
new 16 ohm L-pads in speakers (replacing incorrect 8 ohm pots).
re-coned 15" woofer
new gold rca inputs for vintage preamp
Any CD Player you keep will get the benefit of any future improvements.
I buy LP versions of favorite amazing music, they most often beat the CD, but I’d rather buy ’new to me’ music than churn LP version for CD version.
did I forget to mention, I have a heck of a lot of CDs.
