Thanks for the ideas fellas. All of them sound pretty good. Here's what I've tried so far.

1. Put the 1050 and sub on the same circuit. Still got the buzz.
2. Put a ground lift on the sub amp plug. Still got the buzz.

I'm thinking also that it has to do with the lights and the electrical system in my room. I have a flourescent light as my main light which emits a wonderful buzz. I always have the light off when using the system. Bad NYC electricity wouldn't surprise me.

I tried going with a single line level in also. The volume went down but when turned back up to compensate, the buzz returned at the same level. The crossover on the amp is turned all the way up to make use of the crossover on the 1050.

Yes, the buzz in still there when using the direct inputs and information is being sent to the sub. This and the fact that I don't get the buzz while using a dvd is by far the weirdest part.
