Why not more on 845 SETs?


As a brand-new owner of a Bel Canto SETi40 int amp,(bought used) I was intrigued to see very little in the fora on the subject of 845 SET amps an A'gon. It seems that this provides the best of both worlds -adequate power to drive most moderately sensitive speakers- 40 Class A SET WPC with SET sound. What is the downside to this approach and why don't more of the SET groupies have higher powered amps, giving them much more latitude in speaker selection? I drive 4 ohm 87 db sensitivity Totem 1 Signatures quite adequately with this amp. Is it beacuse of transformer issues, difficulty in finding adequate designs, size or the feeling that this is not a true "SET sound"?
I would like to hear SET-owners' reasons, if possible.

I just bought the Cary CAD 211 Anniversary amps. I am hoping they will be great, I have not received them yet, but they have a helluva tube compliment. 4 x 845, 4 x 300b, 2 x el34, 2 x 6sl7, and 2 x cats eye. 70 watts class A, 110 AB. Anybody ever hear these, or compare with any others? I have been told they are suppose to be world class. I bought these over the Dehavillands, and VAC phi's, and Tube Research GT-200's. Did I do it right?
845C, anyone hear these, or deal with this seller?

I just bought the new Aries g I have the S A P Quartettes. I also have the 845m,tubes. I need sun glasses--compared to the stock 845s--I stuck my speaker grills in front of the amps to diffuse the intense light. While I don't have more than say 150 hrs. on them I am disappointed,so far.These have none of the mid-magic I got from my Sophia Princess 845---but they are much more dynamic. (Audiomecca/ Placett passive and AU 24 wires)
The 845M tubes are bright (light-wise)! I understand from the Supertnt.com web site that they are no longer available. There is a lengthy explanation about this; from the clunky Chinese-to-English translation I gather they are redesigning them.
