For extreme metal? You bet your ass. That is why a lot of us are hoping someone eventually builds a high quality ss amp. One that rivals the quality of even the midrange boutique amps.
The problem is the market is just metal guys. It would sell so few models. Last one to try it was ISP with the theta, and that is one of the amps on this thread. I wanted one pretty bad, but the reviews were so mixed.
I think this is why companies like engl and revv and mlc exist. They build tube amps that are sterile to mimic what people want in an ss, then rock guys buy them and want organic.
