This RCA CD-9500 CD Player is a professional series device that has been tested and works well. Frankly, it looks barely used except for some minor scuff marks where it was slid in and out of a multimedia cabinet. If you've got a large CD collection, this is the device you want!
It has a CD changer capacity of 301 discs and one slot to easily load and play a single CD. Aside from the standard RCA outputs (which you would probably use to connect it to your component stereo system), it also has a digital optical TOSLINK audio output (which I tested, and it works perfectly).
The optical link makes it easy to connect it to your modern TV or sound bar (with an appropriate optical cable which is not included with this player). Although I figured out how to use the CD player while testing, it does have many features. Needs a big box and weighs 20 lbs.
