Regardless, I'm still quite pleased with my LPA-1 & M80 combination.

Volume on my AVR maxes out at +12. I've been there once with the LPA. Playing relatively quiet solo piano music in my 3400cu ft room, that was pumping out 105db sustained with peaks at about 110db from my sofa, 11' away from the speakers. The amp was definitely starting to clip, and my head hurt. I backed it back down to normal listening levels within about a minute. That's supid loud. Hearing-damage loud. I don't know why I'd ever want to go that loud. It's not music anymore, just noise.

It's kind of like my car. The speedometer goes to 160mph, and I know that the Euro version will go 150mph+, but here in the US it's governed to 135mph. I suppose I could be mad about it, but it's just unused potential.

However, in Randy's room, more than twice the size of mine, I can see where you might need more serious amp power.
