Keithmundy,
My Luxman MQ-88 can drive my Verity Fidelio Encores to incredible SPLs in a room that is 15 feet wide, 25 feet deep, with a ceiling height of 8.5 feet. The MQ-88 is a pure class A at 40 watts per side into 8 ohms. In my experience, either that is an overly conservative rating, or those are some of the most robust 40 watts I have ever "heard" . . . !
