Terz,
I don't think so. I think if no signals are coming out of the amp to the other channels (even if they are hooked up) then the WPC gets distributed between the 2 channels that are operating.
Jason,
I have been browsing the Emotiva forum, they are not planning on releasing a 7 channel amp (XPA-7). They are going to stick with the UPA-1 (previously known as the LPA-1) and modify it for 7 equal channels of 125 wpc into 8ohms, and 225 wpc into 4ohms, the new price for this unit will be $649 or less (I guess they haven't decided yet).
This is also an option for me.
