Ground Loop Hum caused by hardwired AC MAINS FILTER - help needed

Hello,
I was wondering if anyone had had a negative result from installing a hardwired mains filter at the house main fuse box. I was considering a THOR DRM95-20A HIGH CAPACITY  AC MAINS FILTERED PROTECTION
https://www.thortechnologies.com.au/product/drm95-20a/

I was mainly referring to ground loop hum caused by having a device in the mains box. I do have a dedicated line for my audio. 

Thank you for any comments or advice.

Hi,
No, I haven't tried that. It makes me a little nervous to cut out the ground. 
But I guess I could try it. 
So, if the component with the two prong adaptor stops the hum, then I should try grounding it with another component instead? Is that correct.?

I believe so. At least you will have more information to work with and someone more knowledgable than me (like erik or others) could make some good suggestions.

Remove any incoming coaxial cables, like for Cable TV, Satellite, etc. first.
