No, it is not something necessarily "fixable" by Onkyo. It has to do with ground loops and AC noise. Some equipment is more sensitive to it than others - why are you freaking out when you haven't even figured out if you are affected by it or not?
My $3299 Parasound AVC-2500 was more sensitive to AC noise than my $1699 Integra DTC-9.8. That right there shows you that its clearly not a quality or expense issue, just a matter of how the electronics work in some people's house vs. others.
Also, in addition to the $50 transformer which works wonders, I'd advise plugging all of your gear into the same wall plate. If you, for instance, plug most of your gear into one outlet and then your subwoofer into a different outlet across the room, it can cause problems like this.
