Preamp for a Marantz TT15..suggestions please

I recently purchased a used Marantz TT15 with the Clearaudio Virtuoso Wood cartridge. I would like some suggestions on a a phono preamp to pair with it. I currently have a Musical Fidelity LX2-LPS and like the way it sounds with my Denon DL-110 on my HK t65c. Both cartridges use the MM side of the phono preamp, and its becoming a hassle to plug and unplug. I would like to stay under $500.00. As always suggestions are greatly appreciated!
