Interesting...
the CS 3.7 are certainly power-hungary speakers. The only integrated amp that I would consider, would be, the Anthem 225. A perfect fit for these speakers.
Follow Ups:
Well, they are still 91db/watt sensitive as well. You can push a pair of them up to close to 100db without all that much power. At a 3 meter listening position in the room you probably can get to 100db on less
91db X2 speakers = 94db about
drop (in room) at 3 meters about 3db (it is much less than theory thanks to reflections...been there done that got the measurements)
So,
91db/watt for a pair at 3 meters (already kind of loud)
94db = 2 watts
97db = 4 watts
100db = 8 watts
103db = 16 watts
106db = 32 watts
Now, I don't know about you but my normal listening sessions are in the low 80s with peaks probably around 100-103db. Often lower than that. If the music is heavily compressed then the average is higher but the peaks similar i would guess.
This illustrates quite nicely that a 20 or 30 watt amp with sufficient current drive for lowish impedance will work great with the Thiel in a normal sized room (up to 600 square feet or so). Both the VAC 30/30 and KR audio VA350i meet this criteria nicely and sound worlds better doing so than the SS amps under discussion.
If the speaker doesn't compress heavily until at least 100db then this is relatively accurate. Of course insensitive speakers like ATCs will start compressing very early and will of course need lots of power to reach these volumes.
Interesting...
They can drive just about any speakers you can throw at them. They will drive the Thiels quite nicely.

And sound like crap doing so. You guys seriously want an analytical sound it seems.
Thanks Again! Freo-1.
