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

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.

A - I am a huge fan of Furman gear. It won't resolve most ground loop issues. 

B - NEVER remove a center/ground pin from an AC receptacle. 

C - Cable/Antenna ground loops are super cheap to resolve. :)

Though with powered antennas like for DirecTV, you'll need a more expensive version.
