Eldart, to some point it's true, but if the signal goes bellow the tolerance input on a certain volume level than the electric loss isn't negligable.
In the digital source of my primary system I have a high output device which is EAD DSP7000 DAC which is flat linear at any volume and cares none about the wire wether it's copper or silver. However when I did an experiment with the generic CD/LD player(used in the different room) I found that connecting it through the copper ICs v.s. silver ones inflicts loss of a detail at even higher volumes while with silver ones more details are heard. Nontheless to say that the sound is still crap through both wires but that due to the poor analogue output but the voltage drop in the wires seemed to be non negligable in that case.
