Pretty sure the Trinnov is the only commercially available unit that can do 34 channels and he needed processing at the moment. There are others that are close behind.

I'm pretty sure most AVR's are limited to less than 13 channels when using a separate amp to power the channels the AVR can power.
This should change in the near future, I'd assume quite a few manufacturers are considering building AVR's with more pre-outs.

I can't jump in this round, stuck on the sidelines watching it all unfold.
