SS amps. Why so much power?


I though that there was so much tube amp talk on this page lately, I'd put up a SS thread. Why do so many people buy the big SS amps that have 200,300,500 watts of power? Is it because the speaker you want is inefficient and you need lots of power, or do you need to play real loud? Or is it a status thing, like my amp's bigger than your amp, or what? Do you buy a big amp first, and then look for a speaker with high power handling? Or do you pick a low efficiency speaker you like and then look for a big amp to drive it? Do you subscribe to the idea that if you have alot of watts, the amp will sound better at lower volumes? I've noticed that the majority of AudiogoNers go with high power SS amps and low efficiency speakers. What gives?

I think the reason some use a high wpc amp is ego.
My d*&%k is bigger than yours type mentality.
I have a friend who has a 240wpc amp with 88dB speakers.
Mine is 30wpc with 92dB speakers.
His plays loud.Mine plays loud.Is his louder?? maybe a bit but who's going to listen that loud? Im a head banger.I get more than enough volume with my set up.
My amp sounds great at low volume or high.
It makes no sense to pay for watts you wont use.
Wanna go deaf? get a high wpc amp and blast it! Want music? get a low watt single ended amp and blast it or just enjoy it at a safe level.
For me, it's a matter of bass control and slam. My speakers are 91dB efficient, but have 15" bass drivers. Lower powered amps just don't control the woofer as well, at any volume. Very noticeable in the low bass region (below 30 Hz). My $0.02
I guess it depends on the person. For me, I had 87db speakers with an SS amp that was around 35wpc. It just didn't sound good to me. Even at 1/3 or less of full volume, the speakers sounded thin and lifeless. Then I got an amp that had 175wpc into 8 ohms and 250 into 4. It really made a difference for me. Everything sounded fuller and less strained. Perhaps if I went for a 300-400 wpc amp it would make more difference yet? I don't know. But I'm glad I upgraded in power.
Most solid state amplifiers prefer low impedance speakers. Most tube amplifiers prefer higher impedance speakers. On a reasonably high impedance speaker, a much lower powered tube amplifier should be able to drive the speaker better than a high powered solid state amplifier.

A good example is the SoundLab speakers. They have a reasonbly high impedance through much of their curve and will generally laugh at higher powered solid state amps, while a 220 watt tube amplifier, like the Wolcott (Hi Albert & Duke), has no trouble with them whatsoever. Even much lower powered tube amplifiers do a very nice job on them.
Greater control of the speaker plus I play my music loud occasionally and having more power than I need means that I will not clip the amp which is the best way to blow up a pair of speakers.
