Epic 80 HT 7.2 system. First, thanks to those who answered my previous post.

Got two more questions:

Will my Onkyo TX-NR905 be ok with this system or will I need to drive the fronts with another amp?

I noticed the system uses 4 QS8 v2 speakers (2 side, 2 rear). Wouldn't th rears be better with M22 V2 (bookshelf) speakers than the QS8s or should the QS8s be used instead?

TIA
