What pre in the $500 pre owned market

I just picked up a Pass Aleph 60. I am looking for a pre owned pre amp to go with this amp, My system is as follows.

Audio Note CDT-1
Mccormack DAC-1 /w upgrades
Jupiter speakers. http://www.jupiter-audio.com/pages/europa.html
I also have xm hooked to this system through a separate DAC.
I am thinking about a quicksilver linestage.
Also thinking about a mccormack tlc 1 pre.
Not real high end but it suites my needs.
Any other pre amps I might want to consider?
Like I stated I am looking in the $500 rage , pre owned.
I also have a NAD C 541i HDCD Player hooked up so the wife can listen to her CD-R as I do not want her playing them on the Audio Note.

Thanks Brian
