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 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.

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.

Thanks for the welcome Zt000. I'm definitely open to more elation, heheh.

The tubes that I have in there right now are a pair of standard 845s I purchased from Upscale Audio. I plan on looking into the 845B as well.

In the past, I've spent a lot of cash on NOS 6SN7s and 6922s for my other components, but was hoping to stay away from the NOS 845s because of their even higher cost. However, one thing that makes me feel better about this tube is the long life expectancy I've been reading about.

What are some of the 845 variants I should look into, and what are their corresponding prices? What are their sonic charactersitics?

Thanks!
