Absorption of digital hash


Berkeley uses material to absorb stray digital noise. Anyone know what they use?

I put shungite between tubes and tranformers on my Wavac EC300b as well as on top of all my power supply transformers. Clarity and Impulse!

Thanks it is good to know for anyone...

 

Now try some quartz or herkimer diamond near the shungite or in his place at some point to reach an even better balance ...Experiment and listen to aim at the right balance and spots...

Shungite tend to compress sound ... ( it shield from EMI too )

Quartz tend to decompress it ...

balance is key ...

@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.
