I just took the plunge into the world of seperates and purchased the 990/7125 combo. The amp arrived Friday although it has some cosmetic damage(I'll have to wait till Monday for a reply from Outlaw on that). I did confirm that it's fuctionally ok. The problem I have is no output from the subwoofer(Sunfire). I have an oppo bdp-83 connected to the 990 by both direct multichannel analog 5.1 and stereo analog. Nothing gets sent to the sub from both inputs whether it's bluray, dvd or cd. I swapped the sub connection cable between the oppo and the 990, still no luck. The connection between the 990 and sub is good as the test tone during the set up came through the sub loud and clear.

I'm guessing I have a setting wrong somewhere. I followed Gonk's set up guide for the 990/oppo and have the secondary audio of the oppo turned off. The output is set to bitstream. The set up routine of the 990 did recognize the sub as present. Anyone's help would be greatly appreciated.
