Hey all, Would love to get some feedback on power amps. I've always had a powered head (currently Eden WT-400 and a Hartke 3500), but am ready to get a nice pre-amp and build a system. My short list of pre-amps are: Demeter & Alembic, but am intrigued by the new Fender TBP-1. I've heard how Stewart World, Crest, Crown, etc., are so great, but they are expensive, too. What about Carvin? Thanks.
