I have spoken with one D200's owner who used Stillpoints ERS paper inside each D200 case just as a precaution to contain any possible residual EM and RFI noise. On the other hand, I have not heard that such EM noise is an issue with Dusty's design, unlike most other Class D amps. Could Dusty or others please comment on whether they have tried this ERS tweak ($25 per sheet), and whether it has any value in sound quality, or reduced interference with other components? I am planning to place the D200 monos side by side, one shelf immediately beneath a SS preamp in a very tight rack set-up.
Thanks.
