Speaker hiss from sub

My REL subs are causing my speakers to have a hiss, which I can hear when the system is off, but the subs idling. It goes away if I run an extension cord into my power conditioner (PS Audio PowerPlant). The subs are connected directly to my amps. Any ideas on solutions without buying multiple conditioners? I tried a simple plug in Isotek wall wart that is supposed to remove noise—no dice. Also tried a better power cord no improvement. Tried moving the sub interconnect around no change. Only way this his goes away is with the power conditioner.

 

Any ideas on a solution?

Hiss goes away when I unplug the power for the subs but have them connected to the amps. It also goes away if the subs are powered but they are unplugged from the amp.

I haven’t, I’ve only run the Neutrik cables that came with the sub—I don’t have RCAs that will go far enough. I have wonder if running RCA from the pre would help but part of the advantage, theoretically, is to run directly from the amps.

I have emailed Music Direct to see if they have any ideas.

Solved for $2.89! On a suggestion from Music Direct I got two “cheater plugs” from the hardware store—hiss gone!
