A Low Cost Pleasant Sounding Used CD Player?

For under $200 you can get a new universal disk transport from Sony which plays CD, SACD, Bluray and 4K including a vast range of audio formats including multi-channel and Dolby Atmos.  You get two HDMI outputs, one purely for audio.  Don't even bother comparing the purpose-built HDMI with USB ...

buy a used Rega Saturn and replace the laser  you will love the sound.

Happy Listening

Good suggestions above.  Let me suggest another way to go.  If you have a DAC then you can use a CD Transport.  You can also use a CD optical player that when attached to a hard drive can rip your CDs or can just play them when attached to a DAC.

 My NAS is a Melco N 100.  I use the Melco optical device primarily to rip CDs but every now and then I just play it from the device.  I’ve done the same thing with Apple Optical devices.

  The OP said he rarely plays his CDs, so if he is interested in ripping them to a server an optical device that both plays and rips might make sense

I have had good results from NAD CD players from the early 2000's like the the CD 521 BEE or even the earlier CD 520. They sound good via their native DAC's or as transports. Unfortunately, prone to failures and burnt out displays. Also Rotel's from the same era such as the RCD 951 are good transports. The native DAC's are less listenable (except for HDCD's) but they are built like tanks.

I also have had excellent results with NAD CD players. I still have one in my secondary system. They are smooth sounding, no digital glare. I also enjoyed my Rega Apollo-R, again very smooth. I would have kept it, but when I reconfigured my system, there was no room to accommodate the top loading lid.
