Oh, your modular is ∗completely∗ free of noise? ;-) Of course you
didn't say that, so consider this:
Wendy Carlos said that building a Faraday cage around her entire
studio reduced the noise level throughout. She concluded that RFI
(radio frequency interference) is usually heard as broadband noise.
So, where there's electrical noise (i.e. everywhere), there may well
be an RFI issue.
Fortunately, the noise level of good gear is low enough that we
needn't obsess over this. I'm sure not interested in shielding my
entire studio room! I'm not even sure how to do it.
