Agree that traditional speaker package will sound better, but if you've short-listed style speakers, it must be for a reason. I don't know about you, my Wife is pretty easy going. But I would have been kidding myself if I thought I was gonna get 5 (or 7 in my case) full size speakers and stands around the room.
You've gotta listen to the MT-30. I love mine and wouldn't swap it for anything. I don't know where you are, but I got mine up at Tottenham Court Rd at the end of last year. You should be able to get the 5.1 for around £1275 (I got 7.1 for £1460 including delivery)
Don't forget that you can get the MT-30 in Silver, Black & White. I believe the KEFs are only Black or Silver.
Also. You only ever see pics with the M1s on their chrome stands. The wall-mount brackets are different units supplied in the box. I met a few people in the trade who didn't realise this, they told me the chrome stand spins round for wall-mounting.....Wrong!
