Well, for one thing comparing watts to weight is not a valid way to compare amps. Probably comparing watts to watts would be a better way to go. What are these secret SS amps you are referring to and what is their power rating?
Two things to consider are 1, the input sensitivity of the tube amp might be higher (which does not correspond to output power directly), and 2, a lot of folks drive tube amps into clipping regularly because they know their soft clipping will not hurt their speakers the way solid-state clipping distortion will.
Did you just get the 3502s; I didn't know they were available yet? What type of output tubes are you using in them?
