Anyone hear the Von Schweikert DB-99?

Larry, just sent you a email. I've had two pairs of dB's,, the first pair when the model went into full production some time ago and a pair I recvd a month or so ago. No hum, buzz or any other sonic abberation. Turn the amplifiers pwr'ing the bass modules off and see if you still get noise. If you have another amplifier that you can A/B that too would be great. Power conditioner, grounds, ,,,? When in doubt contact Kevin at VSA. Your 99's should be dead quiet.

The hum comes off the speaker amp.I have an inquiry into Kevin at VSA per Jack's advice.

I do hear some hum in mine, but it's from a pre/amp I've used while "preamp rolling." The built in amps in mine are very quiet.

I have no hum but... I am having a problem with the built in amp in one of the speakers kicking off and on during complex/heavy bass sections in music. Am changing tubes currently in my mono blocks to see if this helps. Does anyone else have this occur to them?

Tony,I wonder if the amp is clipping....email Kevin at VSA...he's very responsive and helpful....good omen for service with VSA if you need it.
