I agree, in the extreme amps are impacted by the size of the room and more obviously the speaker load/characteristics. You probably wouldn't go with a flea powered SET amp if your room was 25 x 35 for example, not unless of course your were using something like a KHorn which has a sensitivity of 104 db...even then, I would want more than a couple of watts...
My limited experience has been that very sensitive speakers seem to do best with lower or moderately powered amps, whether tube or SS. Tougher loads, like a Magnepan panel speaker are much happier with as much power as you can throw at them; think 500 watt SS or BIG tube amps..
I stand by my earlier points in this thread. To me it makes little sense to choose an amp first; ultimately the choice of speaker has the greatest impact on the overall tonality of the music, the type and condition of the sound stage, and the overall response you get in a particular room.
Find a speaker you like/love and then do some hunting until you can find the very best amp that matches well with the speaker (and its particular design characteristics) and one that is powerful enough to drive the speaker to acceptable sound pressure levels in your room.
