Would the M22's be good for a surround speaker or am I better off with the QS8? I'll be listening to music as well as HT viewing/gaming, probably more music, 60/40 . I just want to know what to pair the M60's with

(which I may be purchasing after I audition them against the Paradigm Monitor 11's, or maybe the M80's

)
Also, with the QS8's, they are 6 ohm. I have a Sony STR-DA7ES receiver, will there be any problems pushing these? I think I know the answer but I want to make sure. These will be my first set of qaulity speakers.
current fronts - 20 year old Kenwood "digital" speakers (thats what's on the front

, my pop gave them to me) with a 12" woofer, 5" mid, and a 2" tweeter.
current surrounds- Polk audio Rti 25's
center - CSi25
10" KLH woofer from Costco (hey, it still sounds good)
Time to upgrade! I'll put the old stuff in my bedroom
