so the used Eden d410t arrived today, and now my GASing for an amp head is even more intolerable. I'm looking at the ampeg PF 500 or the carvin bx 500, both for wattage and budget purposes. the problem is, I have no real amp savvy, and no good stores nearby with acceptable bass amp coverage. (Nothing to try out) other than the actuall specs of the amps, what would TBr's say about the voice and overall quality of these heads? or do you suggest some other third thing? all your input is helpful. and yes, i have checked the forums.
