I'm interested in M60ti ,VP150, QS8s but I'm concerned if the soundstage and midrange of the M60 will match up to my JBL 4312 Sudio Control Monitors, their soundstage is excellent no matter where I'm at in the house, or outside in the backyard. But it's time for new center and surrounds and I'd like to stay in the same family, not to mention upgrading to shielded mains. I have;
Sony STR-D3ES receiver
Klipsch RW-10 sub
Klipsch R3II center channel that I screwed up because of playing music to loud in surround mode!!
Panasonic DVD- to be upgraded
Yamaha CD player- to be upgraded

Any advice....good or bad.
