A few more comments:
Surround/DSP/Room Correction: Nope. We've done surround before, and it's now a very specialized biz where HDMI interfaces are absolutely critical. There are only a handful of companies doing HDMI well, and they have the stomach to tolerate ongoing changes in the spec (1.3, 1.4, etc . . .) Mike and I are of the opinion we won't be getting back into surround. DSP and room correction--again, that ain't us. Our own digital filters, yeah, but not DSP for crossovers and such.
The "midrange" balanced amp (which really is an end-game product, in terms of performance) will be solid state. The "statement" balanced amp will be a hybrid.
