I auditioned a pair of these today and just like that, my speaker budget magically doubled :-) Needless to say, I was very impressed with what I heard, although it was only 2 channel. I would like to use these badboys in my theater, with the MCS-1 for the center, and the SCS-4 for rears. Does anyone have any experience with Thiel in an HT setup?

MCS1 is a great match.

I have a pair of 2.4's with the MCS-1 as center and love it. If it works in your setup the MCS-1 stand is expensive but extremely nice.

I also have 2.4s with an MCS-1 centre and 4 x SCS-2 for surrounds.

I'm sure you'd be happy with the 3.7s and MCS-1. Hopefully they'll eventually release a new centre with the same tweet / mid as the 3.7.
