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.

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.

John Thank You for the advise.
Sorry to have taken so long to report back, got a little busy over the past two weeks. Was able to get all the testing done and the 2Wq's are still humming. Good news is the Grado/VPI are not the source, with it completely disconnected (power and interconnects), the hum is still there. Tried connecting everything to the same phase leg, with and without a ground wire and the hum seemed to get worse, the ground wire didn't help at all. Disconnected all components to see if any were causing the problem, found a worse ground loop when the AVR was connected, was able to correct that but with the AVR disconnected the front speakers were dead quite, connected the 2Wq's and the subs started to hum. Funny part is they are not as loud up close as they are when the two combine between the speakers. Good thing is you can't hear it while the music is playing. Guess this is something I'll have to live for a little bit. Anyone have any more suggestions.
