Why does my tube amp

I feel very comfortable in my Subaru XV Crosstrek. More comfortable than in Mercedes Benz E350, but I doubt that I can outrun E350 with Subaru XV.

What is the 110 lb gorilla, I mean SS amp, being compared?

Also what kind of music are we talking about? Any electronic rock/pop music with a lot of bass? Or big band or large scale high quality classical recordings? how loud do you listen?

Those are the things that will often push the limits of what a good quality lower power tube amp can do with speakers that represent a tougher load.

I am not saying teh PSBs are a harder load necessarily. I have heard PSBs running off similar power tube amps from ARC and Rogue and the results were quite good.

If its snowing, you can. Quite easily.

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?
