Do I esentially have a class A amp?

I run my system under 85db and my speakers are 91 sens. With my Parasound A21 running the first 10 watts in class A, I'm in the same position.

I suppose that's true. In my circumstance, I bought a 250 wpc Parasound amp, and as it turns out I don't like the volume above maybe 10 wpc with my speakers in my room! I could have bought a 100wpc amp instead. But on the other hand, I do occasionally crank it up on some passages and it's jaw dropping to hear a gorgeous vocal or cello.

Perhaps there's a benefit with having too much amp!
