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.
