ERS Paper for CPU to reduce EMI reflections

Why wouldn't it? All components generate EMI which interfere with the other components. I changed my 1GB RAM into 512MB and it sounded worse (should have sounded better), then I found the reason, my 1GB module has a metal casing around it which keeps some of the EMI inside it. Shielding the RAM should give bigger differences because the direction of the EMI is facing the mainboard. With the CPU it's facing the side cover of the case, but the case makes some of the EMI reflect back into other components on the mainboard. So when putting a sheet of ERS Paper on the inside of the cover it should give improvements.
I have tried this with the DSP board inside Cary 303/300 and the improvements were night and day. The Cary blocks the external EMI because of the 2 metal covers (I didn't hear a difference with ERS outside the case). But inside the small case there were reflections from the CPU and other components on the DSP board. So I covered the whole inside of that case with 2 sheets of ERS.

| why not put the ERS paper directly inside the chassis? Much better! In fact, the DAC fell off my list of candidates for future upgrades-not bad results from a $20 sheet of paper. Next up was my tuner, which I use to listen to New-Age music on Hearts of Space on NPR . Huge gains here, too! This was really fun! Throw a sheet or two of ERS paper into your component, and feel like you just saved yourself a thousand, or two, or three thousand dollars in a major component upgrade! Man, this stuff is dangerous! It could put hundreds of American craftspeople and thousands of Chinese out of work if audiophiles started using this stuff instead of buying newer, more expensive products. |
When he said $20 of ERS gives a $3000 improvement, he wasn't kidding.
