RFI is very real. Noise from amps, broadband, flourescent ballasts, etc., is very real, and very much hearable.I'm not at all certain that this is part of the "resonance" discussion.
Regarding mechanical resonance...also very real, and most definitely hearable. As has been demonstrated, every room has a resonant frequency, and everything in that room affects the resonant frequency. Hence bass traps, carpets, draperies, and the distance of the speakers from the walls all have an affect.
Every cable has impedance. (And resistance, and capacitance, and inductance, and reactance, and, and, and...). The question is whether or not any of this is material. That is, can you hear it, or can you hear the difference when any of these parameters change within the normal ranges of normal cable materials at normal ambient temperatures and normal audio frequencies.
No. RFI and line noise can cause resonance in a cable. The resonance is at such a low level that it is not discernable by human ears. I'm not saying that the RFI and noise aren't discernable, they most certainly are. I'm saying that any resonance set up by these phenomena are below the threshold of human hearing.
Clay,
