Pre-Amp Recommendation

Thinking its time to update/upgrade. Have a 10-year-old Audio Illusions Mod 3 (with phono card). Rest of system is Audio Research VT 130, Wilson Witts, Audio Research CD 2, TNT 3.5 turntable, Audio Research PH 3, and Magnum Dynalab FT 101A tuner. The only balanced front end equipment is the CD 2. Pre amp needs to have balanced out. Budget of around $2000 used. Got any recommendations?
