Furman solves ground loop issue?

I have a serious ground loop problem with my analog side. Digital is dead quiet.
Loud hum comes from the speakers when analog input is turned on.
Becomes louder when I increase gain.
A salesman said that if I plug my analog components into a Furman PL-PLUS C - 15A w/Voltmeter 
this would solve the problem.

Have tried all the usual methods-cheater plugs, transformers, using another circuit, grounding with copper wire, switching interconnects, but nothing works.
Something is going on between the pre and the phono stage. Tried a different make phono stage and the problem is still there.
Have spoken with people with all brands involved and nobody could help me.

Anybody have any experience with this product? Would it solve this hum problem?

Thank you

Thank you. I hope I can find something that will work. It's been a while now and I'm getting worried. I've enjoyed analog too much to be without it besides the money spent.

you know, honestly, while I do not recommend cheater plugs, if using them, removing Cable TV, and or making sure your pre and turntable are hooked up to the same outlet doesn't fix it: 

1 - You don't have a ground loop, you have noise. Try turning everything else in the house off. 
2 - You have a bad phono stage.

I just want to share my experience with my fellow audiogon.  I have major ground loop problems even with a new electrical main panel and multiple ground rods and ground to the main water line.  I use the Ebtech Hum X Ground Line Voltage Filter which can be bought on Amazon for $79.  This Ebtech Hum X can also be found on Musician’s Friend, Guitar Center, etc.  I use 3 Hum X on my 3 amps which work wonders.  Btw, I also have RGPC Substations & 600S & 400S, Shunyata Hydra V-Ray & Hydra 8.  Only the Ebtech Hum X works with eliminating the ground loop hum.  You can always return it if it doesn’t work in your system.

Good luck,
Tuan
