Actually, it can be a concern; it certainly bears investigating, specifically with respect to high-source impedance leakage current.
So, my question for EvaAnna Manley, which I may write to her about is....do these SMPS output high-source impedance leakage current?
High-source impedance leakage current is to known travel down almost all sorts of cables and specifically adds additional noise on the ground plane of digital signals, which causes increased threshold jitter, which is audible.
Here's the problem with detecting High-source impedance leakage current: it was only discovered in Oct. 2017, and...you have to build very specialized test equipment even to detect it.
The question is: do these SMPS designed by Bruno output these leakage currents?
