Well I have the full MT-30 package (7.1).
I couldn't ask for any more out of it. It sounds detailed and dynamic. The sub can rattle the letterbox when I crank it, and my lounge is at the back of my house.
I don't use it for stereo though, only music DVDs (which sound great)
It looks great too, if that matters to you (seeing as you're looking at it, I guess it does).
One thing. If you're thinking of wall mounting the M1 sats, there's a dedicated colour coded wall bracket supplied in the box. It's NOT the chrome table top stand that swivels around for wall mounting like every dealer I visited says it was!!
Try and have a demo
