Maybe I can ask this here. An admittedly esoteric question.

I have a 7.1 setup, and I've always gone with a 2 ch amp plus a 5 ch amp. Obviously, then I only need to power the 2 ch amp when listening to CDs, lps, etc.
I stack the amps (yes, with spacers in between for air flow.

). But I also stack an AC balanced power box on top.
OK, so I've always looked at the 3B-SST and the 9B-SST. But the 3B-SST isn't deep enough for me to put the balanced power unit on top. (It has to go on top, because it's a little narrower than the amps. Wouldn't look right if it was on the bottom.)
Ahhh, but now there is the 2B-SST C, which *does* have the depth I'd need.
... But I want the greater power of the 3B-SST. Any chance they'll ever be a deeper version of the 3B-SST?
