And the earth is still flat!
Regarding the Million Dollar Challenge, article said Michel Fremer and that man couldn't come to terms on details of the test, not that he wasn't willing to take challenge.
Chain of components would, for results to be valid, have to have sufficient genuine transparency and resolution to delineate subtle differences between speaker wires,
if they exist. Using some mass market mid-fi speakers as test speakers doesn't necessarily prove anything because they may be so opaque that, as long as you feed them a decent, intact signal and use an amp that can drive the speakers appropriately, they will always sound the same.
I've heard Wilson speakers at audio shows, but never owned them, so I don't know their characteristics intimately. I have read that Dave Wilson believes that speakers are most important part of chain (vs. Ivor Tifenbrun of Linn turntables, who believes source is most important), and I think he voices his speaker line that way. He even demonstrated at some audio show using an
iPod as source for an otherwise rather expensive chain of components. I would guess that as long as he was producing clean signal path, and amp had sufficient power / current, etc. to drive Wilson speakers, predominant characteristic you would always hear is Wilson house sound.
That lady did hear a difference, though she may not been able to verbalize, in audiophile terminology, exactly what difference she perceived. Her comment about more spaciousness could refer to picking up more low level detail in terms of ambience cues ("air") of original recording space as encoded in recording, or, something a home theater fan with good chain of components and a really accurate sub that go really low may experience, spaciousness is recreating better sense of the space and scale of original recording (e. g. large church), where those very low frequencies, now being sent to speaker more cleanly, allow you, in your mind's eye, to "see" / sense / flesh out a more realistic scale of original recording space, to sense walls of church, to hear rumble of extraneous subway running underground at very low spl, etc. Speakers themselves obviously would have to be able to dig down into those very low bass frequencies accurately and without excess bloat, and speaker wires would have to be able to resolve such low level detail, if they were in original recording (the ridiculous price tag a cable manufacturer puts on his cables, including absurd prices of Shunyata products linked below, would be a totally different issue vs. whether or not all speaker wire sounds the same).
edit: As for electricity just being electricity, there are a lot of professional musicians and recording engineers who disagree, and have spent
uber-bucks on snake oil interconnects, speaker wires, and yes, power cords and power line conditioning equipment:
"
I have been very skeptical of power related tweaks above and beyond good basic engineering practices like wire sizing, proper grounding and good solid connections. That said I tried to be open to the merits of the Shunyata approach regarding power management. After living with various power cables, outlets and Hydra AC distribution systems for several months while working on my DMP Archive Project, I can honestly say that Shunyata Power Systems do contribute to a more solid, focused and accurate sonic picture." --

"Connecting a power or speaker cable to an amplifier would seem to be a simple matter. Get the largest wire available and make the connection as short as practical. What appears to be simple becomes complex as the physics of the problem are examined. All wires have an inherent resistance, inductance and capacitance. This means that a cable is actually a type of simple filter. The ideal cable would have zero resistance, zero inductance and zero capacitance.
A simplistic design approach would be to make the conductors larger or use multiple conductors to decrease the resistance of the cable. Unfortunately this approach increases the inductance and capacitance of the cable, which our research shows is actually more deleterious to linear signal propagation than increased resistance. Resistance is a linear function while inductive and capacitive reactance is a non-linear function that is frequency dependent. This means that high-frequency information is skewed while phase-shift anomalies are inter-modulated with the signal."
