It is interesting that no one questioned the quality of the connectors so far. The cable could be anything if your connectors are electrically loose. When dealing with "audiophile" cables not only the cables are different, but they usualy come with more robust connectors which may help in making better contacts, I think the toughest audiophobes can't argue that away either...
It seems trivial that if you put to conductors reasonably close the current is flowing through, but how close are those conductors on an atomic scale? :)

Slight misconceptions about the placebo effect in that video.  Making the pills cheap will actually make them less effective, or, ineffective.  If those same pills were 100$ a bottle, with the same BS contents, they would be much more effective....

For Audio frequencies the effect is only felt in the wallet :)
However from either creek or tannoy  they recommended a minimum length of speaker cable (4 metres if I remember correctly .)
Which would increase the impedance.

Sorry to veer off-topic, but this always hits a nerve.  The best, and likely the only scientifically valid, way to know if you're really hearing a difference or not:

Blind/ABX testing

Any claims of being able to discern differences in sound should be ignored unless valid, statistically significant, testing has been conducted.  People who don't even attempt reasonable testing are, at best, fooling themselves.

FFT, THD, etc. measurements, while critical for design and evaluation, can't prove people are able to actually hear a difference. 

It's incredible how many "audiophile" sound quality discernment discussions conveniently fail to even mention blind testing.

Of course even if folks demonstrate they hear a difference, via reasonable testing protocols, it's purely subjective whether it sounds "better" to them, or not.  At least if they can consistently pick out one output over the other 90% of the time, they can legitimately say they hear a difference.

...
"Doug Schneider, editor of the online Soundstage network, refuted this position with two editorials in 2009.[7][8] He stated: "Blind tests are at the core of the decades' worth of research into loudspeaker design done at Canada's National Research Council (NRC). The NRC researchers knew that for their result to be credible within the scientific community and to have the most meaningful results, they had to eliminate bias, and blind testing was the only way to do so." Many Canadian companies such as Axiom, Energy, Mirage, Paradigm, PSB and Revel use blind testing extensively in designing their loudspeakers. Audio professional Dr. Sean Olive of Harman International shares this view.[9]"

Even then blind/abx testing is near impossible to conduct on speakers, starting with that you can't put the speakers to the very same place, loudness levels sould be matched exactly (but at what frequency?) etc.

These threads can touch nerves because there are people that tell other people what they are hearing. Without any tangible or numerical evidence to support any claims then apparently it just cannot happen.

Everything sounds the same, nothing sounds better, no cables matter. If you want to tell people they are tone deaf and it's all placebo then please feel free. Maybe the people you tell that it's all placebo, may have an ear for tuning instruments and have been around awhile.

I don't take offense to anyone believing this, just don't understand how and why someone's belief dictates someone else's experiences.
