OP, hello neighbor.
I have a vintage CD player from the late 80's (Sony) that I like and it still works and sounds great. You are always taking a chance with vintage gear, but many of us are collectors and we like vintage. I also have a Denon and a few others. They all work well. The only CD player that went South on me was the first one I purchased when CD's first came out. A SHARP that lasted about 3 months.
Like many I was into Cassette players big time in the late 70's and early 80's.
I have a few but my favorite is still my Sanyo Micro Processor controlled vintage deck from 1980. At the time, I would play a Vinyl album ONCE directly to Cassette, and then store the Vinyl never to be seen again. I'd just play Cassette.
Like a few said, you can sure get fine sound out of a Cassette. I prefer High Bias Chrome tapes, and I use a Compander to reduce hiss and distortion. I have a DBX Compander that compresses sound to record, and expands it on playback. I feel this exceeds any Dolby noise reduction settings. My opinion of course.
So it's up to you, sir. I enjoy Cassette and CD, but not as much as Vinyl. I typically listen to Vinyl, but it's nice to have alternates.
