I have decided to junk everything and go with a rack preamp and stereo power amp setup. I'd like to find a used one that had versatility (tube and solid state) and a wide range with some great headroom for my Kubicki Ex Factor. It does not have to have a compressor or bi amp outs, but that would also be neat. I plan on pairing it up with a set of Bill Fitzmaurice cabs. Is there anything out there for maybe $ 150 that would do the trick?
