Absorption of digital hash

@ptss That plate is Permalloy. It has magnetic properties similar to Mu metal but is much less ductile. Mu metal can be formed easily into various shapes. 

I have digital equipment all around analog gear and I don't have to shield anything. I do not have any interference or mystery noise. I spend my money on records and not trying to fix problems I do not have. The solution is not to buy equipment that is inadequately shielded.  

Thanks for all helpful responses. I don't have a problem I have an Oppo 205 and thought if this material is good enough for Berkeley it's probably goid enough for Oppo. I have no complaints with my Oppo. 

@mijostyn Totally agree. if a product is emitting RF or whatever then it is not fit for purpose and shouldn't be in the market.
