Which Used CD Player for Under $1,500?

Check www.underwoodhifi.com for the Jolida JD 100 stock and modded units could be your ticket. Also check his modded Music Hall CD 25 and the Shandling. I have the stock Jolida. I love it for the money. Don't forget the Creek, Arcam, and possibly the Rega unit at your price point.

Audio Research CD2!

Meridian 508.24
or for a Bargain if you can find a Gamut CD1R or CD1S (not the original CD1 unless you have monitors) the detail, spacial ease will red book sound amazing.

I second the Quad 99 CDP. Great player for the money. More musical than my Benchmark DAC.

I've only experienced the MF A-3.2 from the ones you list, and found it rather analytical and lean sounding. Plenty of detail but a little lacking in musicality in my system.
