Nuforce with Stillpoints ERS fabric

I have ers everywhere (one of the Stillpoints people is a friend ;-) but I don't think that would solve your problem.

But before you ditch that lovely amp (or the cute dog) could you describe the connection(s) between your TT/TA and the phono pre, including: brand of phono cable and termination(s), ground wire(s), and brand of TA.
.

Are you sure it isn't a ground loop problem? Ground loop hums are easy to eliminate.

Briefly, how did you come to the conclusion it's the amplifiers?

Describe your Voltage Alternating Current system, Romex, metal clad, dedicated breaker, shielded power cords, balanced interconnects, star grounded, cable TV on the same circuit? How does you FM sound?

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
