I'm needing some help deciding what amp head to get. I'm new to the whole tube amp thing, because all I've ever played on before was an SWR Workingman's 2004 and Ampeg BA-115. I heard that tube amps have more output than solid state. Like one guy said that 300W of tube power is about the same as 5000W of solid state (I realize it's an exaggeration, just using it as an example to explain what I'm talking about.) Is that true? If so, does anyone know how much louder tube amps are than solid state amps rated at the same wattage? I'm asking because I'm looking into buying one of three amps - Ampeg V4B, B2R, or SVT-CL. I've played through an SVT-350 (same as B2R) and it had plenty of power, but if tube amps are as powerful as some say, I'm gonna go with the V4B. I may even spend the extra cash and get the 300W SVT Classic. Any opinions on which would be better as far as power rating? I know tube sounds better, I just want to know which would be most powerful.
