Calling Vandersteen Subwoofer Users

I have a pair of 2Wqs that I absolutely love. There is a small amount of low frequency hum in my system, though. When I plugged in my components to a PS Audio Quintet, the hum was vastly reduced. So I was thinking that I should plug my 2Wqs into something similar. I think that, since the subs are connected to my amp, that power filtering for them might reduce the hum in my system even more. Can I plug the pair of 2Wqs into one PS Audio Duet without compromising performance? All replies appreciated.

Did you try all of the above?
I will assume yes
The Grado unshielded cartriges can hum in a Rega table
more so when cart is over the moter.
You can also try a ground wire from your pre amp to the 2WQs ground post

Sorry for the late reply was away for the weekend. Yes I tried all the above before but haven't had the opportunity to try the ground wire yet. Will try before the weekend though. My system is dead quite until I plug in one or both 2Wq's.
I guess I need to update my profile. I now have a VPI HW-19 Mk IV. And the hum was still there before I hooked up the phono amp. Also on the same note I never experienced the Grado hum with my Rega.
Thanks for the input and will post my finding.

well, becasue of the layout of my system, and the number of components already plugged into the Quintet, I don't think I will be able to test things out the way John has suggested. At some point, I will try to borrow a Duet or two and try them out.

Greetings Bonmapp
you dont need to borrow a duet
just plug everything into even a cheap hedgeclipper extension cord with a few extra outlets to be on the same phase leg.......... Try a basic ground wire from pre amp chassis ground to Subs ground lug
Ig316b are you sure you havent been ordering from web jockies? sorry to be the messenger again
Grados and VPIs also hum together.
