Tube amp for Thiel CS1.5s


I am looking at the following amps to drive a pair of Thiel CS1.5s:

CJ Premier 11a
CJ MV55
SF Power 1
ARC Classic 60

My room is 19' x 19' and the amp would be part of a home theater system but most of the time it will be used for music only. Would I need more power like a SF Power 2 for my setup? Any recommendations would be appreciated.

I have had great results using the CJ MV-55 to drive my Thiel CS2 2's. The smaller Thiels do not present a bad impedence curve to a decent 4-ohm rated tube amp. However, in a room the size of yours with the intention to use the system for home theater, the MV-55 will run out of steam if you enjoy high volume levels. But maybe your choice of the the 1.5's indicates that you do not require high volume, and if you are complementing the mains with a powered subwoofer, I would say try this combo by all means. BTW, I have found the amp to sound its best by replacing the stock Sovtek input and power tubes with, respectively, Yugoslovian EI 12AX7's, and Svetlana EL-34's (the stock 6SN7 drivers are fine).
