I've been researching tube heads alot lately. My quest has led me to the 400+. It has everything I want in a tube amp. Lots of power, 2 channels, footswitchable, graphic EQ, handles 2ohm load allowing lots of cab possabilities, etc..Anyway, I found a 400+ w/ hsc used for a very, very good price. I just bought a Bag End S15-d which is 8ohms rated 200w-400w peak, and was planning on buying another one. Will the 400+ be too much power for these cabs? It should be perfect right? running at 4 ohms each cab would be getting 250watts right? Should I buy it? I think I will regret passing it up, but I need a little positive reinforcement. I have heard nothing but good things about these amps in terms of reliability, volume, tone, versatitity, etc. I know they're back-breakers, I could use the workout.
