Cicero emailed me again. To avoid having to deal with this in two places, I'll shift that here:
Cicero's email: "So, let's assume I do have a problem with RF. Than, there are better ways
solving it. If we assume I do NOT have this problem, than, the DNM cable does't add
nothing at all?"
Simpler to just start with evidence. What evidence do you have that you *do* have an "RF problem"? Without evidence we could spin our wheels forever inventing 'possible' problems... that you don't have. i.e. waste time and effort.
The webpage that was referred to was *specifically* about *power amp* - cable - speaker interactions in the context of the risk of leading to amplifier instability situations. Not about any cables 'sounding better' than others. Nor about other kinds of "RF problem".
