Default Sub hum
I experience a slight buzz from the sub, but not all the time. I haven't nailed down exactly when it's there and when it isn't, but I know I heard it when watching the Grapes of Wrath DVD (mono) and Kagemusha (listed as 2.0, but PS3 display read 4.0). I haven't tried unplugging any devices to isolate the source since the buzz doesn't occur frequently.

Could it possible the sub will buzz only when there's no LFE signal?
