Anyone hear the Von Schweikert DB-99?

Guys, when was the DB-99 SE released? I know the mk II has been out since 2003 I think. I'm just curious since I got my SEs just recently and my serial number is below 0020.

I've had mine sans super tweeter since late June...best speakers I've ever owned....everything I've always wanted...love the bottom end. Only criticism is I can hear low level buzz-hum from one of the built in amps from my listening position 12 feet away...it's not the circuitry or my gear, they're dead quiet...anyone experience this or have a solution? I haven't called my dealer yet to see if this is the norm.
thanks,
Larry

I have Zu Definitions - similar high-efficiency design with powered "sub", internal. I get a little hum from mine too, though it's not audible from the listening seat as the woofers fire in the rear. Sean at Zu told me they could kill the hum, but it reduced the life at the nether regions. Sounds like a design choice to me.

Does the hum come thru the speakers or just from the amp itself?

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.
