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 had concerns about driving my Thiel CS 1.5's with a tube amp but I find that my Conrad-Johnson Premier 11a does an outstanding job on these modest Thiels. They aren't the difficult load that some people make them out to be. I also find that the midrange sweetness of the CJ amp is a very good match for the slightly dry Thiels. I LOVE this combo of Thiel CS 1.5 and CJ Premier 11a. I like it even more than my previous setup that had the Classe CA-200 200w/ch amp driving the 1.5's.

Regardless of what anyone here tells you, if they have not personally tried it themselves, they don't know what they're talking about. This combo works, and it works superbly. Period, end of story.

A supporting online review by SoundStage of the Thiel CS 1.5's being driven by a modest 40watt/channel tube integrated amp.

"That said, I found that the all-tube 40Wpc Jolida SJ202A integrated amp drove the [CS 1.5] Thiels to satisfactory levels without a hitch."

Abecollins: You are right. Per the archived review on Stereophile's website, the 1.5's do not need tons of power but likewise will not play super loud or display extreme dynamics. If one has a small room, this should not be an issue. The review also states that the 1.5's have a very flat "resistor like" impedance (@ 4 ohms) which tube amps love. My peception (about power requirements) probably biased by the unusually small mid drivers in the later Theil designs. You're NOT going to get a huge healty sound out of a teeny (4 inch in 2.2?) midrange driver without plenty of juice!
