Hehehhe I had the same problem with my outputs, although I thought I got a full blown 0 channel amp...
I had the output set to an output that didn't have the preouts switched on, after turning it on and off a couple of times system reset itself and all was good.
I really really have to clean up my mess of wires and start labeling things back there.... Didn't get the 9.9, but I stopped by my dealer to check out the Marantz 8003, he is much closer and I had more time to do so... Still haven't made a full decision on either unit as they both have their plus's and negatives.
Remember I need 2 PreAmps of what ever I choose, so it has to be the right choice for future, I guess we'll see how things pan out....
