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.
