FWIW, I happen to agree with two other posters who suggest that the type of music you listen to and the manner in which you listen to it probably dictates that you would be happier with a good high current SS amp than a medium powered tube amp. The subtlies brought to audio by tubes would probably be lost. That said,
I drive large floorstanders with 92db efficiency and a 4ohm load to very loud levels in a 13x19x9 room using a Primaluna 1 or 3/5 combo. I trade off a bit of bass solidness (compared to a 100wt high current SS amp I have) but since I listen mostly to small scale jazz and classical I suffer no real loss.
Try to audition tubes before you buy, or as another has mentioned restrict your tubes to your pre-amp (a potentially excellent solution for your purposes with all of the flexibility that seperates offer).
