Al, I of course agree, and called out cables needing to be application-appropriate earlier (only to have Nonoise twist my words around), but you know full well that's not what many of these folks are arguing for. They're arguing that two cables that measure alike can sound different. That even connectors can sound different.
To everyone else, regarding what we can and can't measure, I've got news for the non-technical among us, the level of design sophistication that goes in audio system cables, the frequency range and the voltages involved, are just so much child's play in modern electrical engineering. If you've got a new Intel-based PC you have 8 giga-transfer per conductor signals in it, using some incredibly complex signaling techniques. Just coming us with the design rules for circuitry like that takes years of research. Audio cables are first or second year BSEE stuff.
The only thing underlying the controversy with cables, IMO, is that one can interchange them. I don't hear anyone pondering audible differences in circuit board materials, single versus double-sided circuit boards, or the gauge or type of internal wiring, and I think that's only because you can't interchange them. Otherwise I think I would see posts about low-loss versus FR-4 circuit boards.
