EMI Absorber 'Hozox'

Nice something check out , the only products that i have tried which works on the same concept emi absorption is from Alan Maher designs. 

His products did lots of goodness to my A/V setup and surprisingly to my allergies. 

I know Arcam/dCs uses something like this to line the inside of their components. I believe Furutech does as well.

If you're having an EFM problem, it should help.
