Nuforce with Stillpoints ERS fabric

I was using Discovery cables for the whole vinyl chain. I have been changing out cables, MIT, Nordost and Radio Shack, none of them resolve the buzz issue. I even tried wrapping the cables in aluminum foil, did nothing to help. I can move the cables and that also will affect the level of the buzz, similar to an antenna affect. I don't remember having this issue with the previous phono pre, ARC PH-5. At least it wasn't bad enough for me to notice. With the BAT pre I had this issue without the turntable connected. That is another option, replace phono pre and i would rather replace the amp than the phono pre.
Thanks

I replaced the Nuforce with my Anthem amp and the buzz went away, That's how I figured out that it's the Nuforce amps.
I am only using balanced for the amps, I don't have balanced inputs anywhere else. It is not a dedicated line,but I will be having that done in the near future.
I have satelite tv and do not have this issue with anything but the phono playback.

I gave up and sold the Nuforce, I love them, but time to move on. Now I have been scouring the ads for a replacement. Really having a hard time picking something. Should I or shouldn't I go back to tubes? Monos? Should I just buy something to tide me over until something really enticing hits? I have been wanting a VTL ST-150, but they don't show up very often.
My speakers are Von Schweikert VR4jr's and my pre is a VTL TL-5.5.
Thanks for all of your input on the RFI issue and sorry if I dissappointed you in my selling them off.
