$500 - $600.00 preowned cd player suggestions

I've seen the Rotel RCD-1072 CD players being sold on this site in this price range. New $700.00. I have one and it's superb, especially for smooth jazz. It excels at that (i.e. Norman Brown, Lee Ritenour, Larry Carlton, David Benoit, Brian Culbertson, Boney James).

Agon,a used Jolida JD100 is a great buy @$600 if you are not looking at SACD and want to experience the hybrid world of a quality(budget priced) CD player with a great transport.
This is it!

My vote goes for Marantz CD-17MKII. Can be had cheap on used market. Very nice sounding, extremely well built and beautiful looking machine. Also very reliable with Philips WAM 1201 transport that is cheap and easy to replace if needed. Uses same highly musical DAC 7 as higher Marantzes.
As for Arcam I suggest FMJ CD23 that uses same Ring-DAC as $$$ dCS Elgar. Arcam is not so good looking as Marantz but sound is also extremely good. Marantz bit warmer tonaly better sounding, Arcam bit more resolution.
I don`t suggest not FMJ Arcam units. These are dull and lifeless sounding. Same sound you can get for cheapo dvd player.

I used to have a CAL (Calif. Audio Labs) player in the
1990's and really liked it. I thought it was as good as the Meridian 508.24 I replaced it with in 1998. There are a few CAL player and separates for sale on Audiogon now.
I had an Icon Mark II player (later with a Powerboss upgrade). It was very easy on the ears with no hash, ringing, hardness or glare. The soundstage was a bit flat but the tonality was very refined.
