If interested, you could Google up Gordon Gow, President of McIntosh Laboratory (a fairly well respected audio company) and probably find an archived article on 'blind' speaker wire tests. Hint: he didn't find any difference, nor did anyone who took his test.
There are only three things affecting cable & wires in the audio range, and those are the RCL (Resistance, capacitance, and inductance) values. Anything else with a claimed impact is snake oil. Linear electrical theory is virtually 100% accurate in this arena. Things like skin effect (electrons only travel on the surface) have application at video rates, but not audio.
Flame-suit on folks, but a PhD in Physics and almost 40 years of audio experience (sales, trivial design, and as a user) tells me this is the biggest hype area of audio. YMMV.
