Does your BAT?


I have a BAT VK-30. From a distance of 2 feet I can hear what sounds like a motor running. My question is. Do all of the VK-30's make this sound?

I found the problem. My BAT does not like my PS 600. When I run the vk-30 into the wall the motor sound goes away, on the other hand,thru the power plant the buzzing sound is there in full force. I am going to play around w/ some of the multiwave settings on the 600.
BAT's don't like the PS Audio PP. It was all over their (PS Audio) website about 2 years ago.
Half of the PS-600 multiwave options eliminate the motorized sound and the other half exhibit this awfull noise. I was ready to jump ship and try the shunyata. Thanks for all of the advise.
