How many "tube" watts do Maggie 3.5's or 6's need?

I have 380 toob watts, and it's enough, but I could always use more. I have also powered them with a 150 watt Threshold amp. Was ok, but the toobs bring them to life. Me thinks, perhaps the extra watts are responsible.

Room size plays a huge roll, bigger the room the more toob your gonna need. Ive heard the 3.6's with VTL MB450 monoblocks and had wondeful results.

My 3.6R's are in a 17 x 23 x 10 room, driven by Wolcott P220 tube amps (220 wpc) with outstanding results.
