I wanted to share some comments from Gary Dayton, who worked for Thiel for 10 years, and is now at Bryston, and here is what he said:
"CS2.7s are very similar to CS3.7s. They don’t have quite the clarity because of the wood baffle vs. aluminum baffle and top. They have a touch more bass though perhaps not as extended.
"My time as service manager for THIEL taught me that the vast majority of people damage their loudspeakers with underpowered amplifiers because they drive them into clipping which sends high amounts of high frequency signal to the speakers that can least handle it - midranges and tweeters. Those drivers then get burned voice coils. Put another way, listening at levels beyond what the speakers can handle is what damages them regardless of power."
Combine this with the fact that my 2.7s has a low-to-average efficiency rating of 87db led me to get the 1000watt monoblocks. I’ve never looked back.
By the way, do you guys remember this beauty, the Thiel MCS1.2?

Gary said he did the basic design you see there, but the sample wasn’t even playable. He said "the plan was ultimately to use a version of the CS1.7 woofers and the CS3.7s coax. An aluminum baffle cast like the SCS4 baffle in a bent plywood cabinet."
Unfortunately, the plans were shelved after the new owners changed direction, and he suspects the sample is probably in a dump somewhere. I would have loved to have gotten my hands on it, and work with others here to get it in working order!
