Hi John,

No, I have nothing hooked up to it yet. I did have my ipod connected via a 3.5mm jack to rca cable, but disconnected yesterday to see if maybe that was causing the problem but it's not... and I now know it's not the cable because I came across an axiom speaker cable (I guess the ppl that lived here before me had some axioms as well) and the the hum/buzz and vibration is still there.

I'm gonna look into getting another ground loop screw from Axiom and hopefully that will fix it.

any other suggestions in the mean time and in between time?
