Hey GregM, I'm running an AVR110 which is 45 watts all around I think.
I'm currently running M60's VP150 QS8's and HSU VTF3-MKII and it goes plenty loud and clear. I've not had any distortion yet as it has got too loud to push it any further.
The only thing I noticed is that I do not seem to get as much bass from the 60's as I've heard at other places. This could easily be my room/set up/layout though.
For h/t it will easily do the job for you depending on your room size. Mine is 20' long by 10 wide. Tv & speakers on the short wall.
