What's the most hi fi sounding pre amp for under 500, that would be fairly easy to find. I'm looking for a clean pre. I have an SVP, so I have all the tube grit I could ever want, and I'm going to get a Schroeder cab sometime after christmas, and I have a PLX, and with the new pre and the schroeder, I could have a nice hi fi rig, and I can switch back and forth from the SVP and the new one. Plenty of tones. So any suggestions?
