High end speaker cables qualify up there with $300 gamer NIC cards.

I did the old ABX test a few years back with an audiophile buddy and some custom ribbon speakers. We found we could hear subtle but evident differences between solid core electrician's wire used for conduit to wire houses, etc., -vs- finely stranded wire of virtually any type. As long as the guage was sufficient, it didn't matter what brand of speaker cable we used, as long as it was stranded. The thick solid wire though sounded weird and had some obvious phase differences.

My layman's understanding of this is that higher frequency 'sounds' tend to propogate on the surface of a conducter because of capacitance issues, and stranded wire regardless of guage has greater surface area than solid core.

So, in essence copper IS copper, but finely stranded wire seems to handle a wide mix of frequencies different than a solid chunk of copper wire. Just don't use Home Depot conduit to wire your speakers, and you should be all set.

Just go to your local home depot and get the RCA 12GA clear speaker wires. It's like C$1.50 PER METRE. I doubt you can bankrupt yourself with that stuff, but will will sound fine.

I really really doubt you did ABX testing.
Did you buy the ABX testing equiptment?What were your chi sqwuared results?

The ABX Company designed, manufactured and sold the ABX Double Blind Comparator System, which made possible scientifically valid self run subjective comparisons of audio components. The information on these pages is historical. This web site documents the ABX Comparator System and lists the subjective test results obtained by the company and the Southeastern Michigan Woofer and Tweeter Marching Society, SMWTMS. I was one of six partners who formed and ran the ABX Company from 1980 to 1987.

Here is what the ABX tester looks like:

That's a common misunderstanding.

There is a 'skin effect' where high frequency currents propagate along the edge of a conductor. However, it is only mitigated by having stranded conductors where each strand is fully insulated from each other strand.

Allowing the strands to touch each other simply makes them operate as one large conductor - with no reduction in skin effect.

This is one of the reason why major power lines use bundles of wires separated by spacers - when the wires get to more than about 1 inch diameter - simply making them bigger doesn't help much because the current concentrates in the outer 1/4".
