Need some help finding a preamp. The problem is driving my crown xls1000. It seems to need a decent signal to get it going. I play mostly classic and hard rock, and some funk. I've been looking at ampeg mostly, 2p and pro. But are there any other candidates? This is to drive a GK neo 2x12, and a Aguilar db412. Everything that I have seems to barely wake it up. Need some help before I pick the wrong preamp.
