best cd player used under 2k.

i currently have a cal 15. good player but looking to upgrade (you now the feeling). i have read good things on naim 3.5; meridan 508.24 any other suggestions. thanks
I own a Meridian 508.24, and I have found it to be the most phenomenal performer of the inegrated CD Players available. The naturalness of the sound and the palpability of images is staggering. I compared it to the Wadia line, and I found it to be a much more natural sounding player. I have not heard the Resolution Audio player, though, and I hear that it is comparable.
I own a Sonic Frontiers SFCD-1 that was purchased used right here at audiogon. I have not regretted the purchased. I have done in home comparisons with CD players from Rotel, Proceed, Rega, and Audio Research. Everytime the Sonic showed me the way, excellent bass response, romantic mids and very extended yet non fatiguing highs(must be the tubes, I am using Amperex tubes in the output stage) I have seen them for as little as $1600 in the classifieds here. Good Luck.
Just curious, why spend 2,000 on a used CDP with outdated upsampling, dac, filters etc when you can get excellent new outboard DAC with state of the art electonics for well under 2,000?
