Since the birth of remote control in audio it has become easy to switch sources. I have my old blind relay driven switch box with RCA ins and outs but I have not pulled that out in decades. I decided on the wire issue decades ago.
mijostyn, you often call others laymen and at the same time offer a false, pseudo-scientific method to determine the quality of wire. Let's assume wires are measurable and when the wire is reversed, it can change its sound by 1 db. But in your testing device, there are at least a dozen randomly directed conductors, which according to strict logic can give out 12 db of difference and you do not know exactly how much. Thus, you will try to estimate the influence of an amplitude of 1 db against the background of an unknown influence of the same nature, but at a much higher level, which in no way can be done accurately.
You can't measure a wire sound with a device that contains wires, isn't it obvious?
Anton, while all that true to some degree I find it most applicable in comparing performances of the same piece by different artists.You forgot to mention the visceral component to live music that is frequently missing from reproductions.
As far as i can get it, you mean exactly what millercarbon have mentioned above.
