That "tube sound" and power ratings

This might be a newbie question since I've only begun researching tube technology. I understand to some degree the theory that tube sound is partly related to second harmonic distortion vs. the more prevalent odd order harmonic characteristics of SS. If "tubies" prefer that sound (I might be one of them), does it make sense to carefully match an amplifier's power rating such that it is NOT TOO HIGH for the speakers it's driving? If the rating is too high won't that mean lower distortion and hence less tube sound for a given volume for those speakers than a lower power tube amp (in general that is - I realize not all Watts are the same). So won't a high wattage tube amp have less of the special tube sound "tubies" like at their preferred listening volume?

I realize I'm likely missing something here. Set me straight!

Mulveling - thank you!
Great answer. Does every tube enthusiast agree with this?

LOL! Of course not! You are new to this. You will never find every enthusiast to agree on anything. Tubes, SS, digital, analog, cables, etc.

Mulveling loves high power tube amps, nothing wrong with that. My tube amp is 35 wpc and my speakers are 91 dB, no audible distortion. While I agree that no one wants to push their amp to hard, as distortion will rise quickly as you reach the clipping point. Most amps operate in a range where distortion is not a factor. I know of folks driving less efficient speakers than I have with even less power and loving it.

As Nelson Pass once said, if the first watt doesn't sound great, who wants 200 more watts?
Listen to the amp/speaker combo, and don't worry so much about numbers. I've heard amps with high power and low distortion specs sound horrible. Listen to the music and let your ears decide.
