@immatthewj that would only be because they didn't have the right (more efficient) speakers to go with it. So that would also mean that someone into classical wouldn't be satisfied either unless they got more efficient speakers as well.
@atmasphere , although I have tried, classical is not my thing; but if it was and I wanted to hear The William Tell Overture (I hope I got that right) at what was a satisfying level, I wouldn't be looking at low powered SET stuff. And I wouldn't be looking at the low powered SET stuff if I was into death metal either. And most of the posts from the metal guys that do post here, seem like they are into the big SS stuff. I am not saying that I don't think tubes can do metal, but I am saying that I don't think 15 wpc or less is going to do what the average metal guy wats it to do.
