That "tube sound" and power ratings

If you have relatively efficient speakers (89 to 90db or around there) and a relatively powerful amp that's not one of those tiny wattage esoteric gizmos, you can stop worrying and simply enjoy the damn thing. If the amp doesn't hum or explode and is made by a company that isn't insane, and it sounds good, you're only going to be using about 5 watts most of the time. Seriously...I use a classic old school (but new design with better than old amp innards) push pull amp with something like 65 watts per side and, fortunately, all of the watts sound great...who knew? One thing experienced guitar players have learned from tube amps is they all sound somewhat different from each other, and often WAY different based on output tubes, input tubes, yo mama...etc...but reasonably well made hifi tube stuff often defies the techno bullshit schools of design trendiness and simply works. Try one.

I've said it before, but it bears repeating even if I'm the only one who believes it: Tube amps make you a better person, they display signs of life in their glowing hot little selves, and SS amps that just sit there like a metal lump of "meh" are far less interesting regardless of how they sound, unless they have some sort of fluctuating meter on them in which case I give 'em a pass (no pun intended). A home run amp I heard recently was a Rogers (there are others) that had tubes AND a meter...a goal for all tube amps to strive for.
