Calling all Von Schweikert VR-9 owners

Guys:

Do you know what is an acceptable level of transformer buzz for the VR-9s? The speakers have huge, 1,000W digital amps in the bass cabinets, and I'm trying to get a handle on whether noise should be audible or not--and to what degree. My electricity checks out perfectly, so that's not the issue. I'm listening in the nearfield, and combined with the fact that the speakers are 96dB with the bass boost on, maybe those factors are causing the buzz to be audible--albeit slightly--from my chair (7'+ away from speakers). My room is very quiet, so maybe that's adding to the audibility. I pulled the amps last night, and put Lock-Tight on the transformer nut and silicone on the back plate, but the buzz is still audible, albeit MAYBE a touch lower in level. FWIW, when I put my hand to the back panel, I CANNOT feel any vibration. Can anyone comment or share their experiences? Thanks!

Stehno: You are correct. His problem has nothing to do with the speakers. He is experiencing a "ground loop". Is has been diagnosed and the solution has been presented.

Hooper: I am puzzled as to why you would bring this to Audiogon. We are in touch 2 -3 times a day and Von Schweikert also always takes your calls.

Rumney510: The speakers that were at the show belong to me. They are just as "tweaked" as every pair that is built. They are all identical other than finish options.

Who told you they are not available at the factory for audition? That is bad information you have received. If you would like to audition them in the Von Schweikert factory, I am happy to set up an appointment for you at your earliest convenience.
