Speaker Cables? why all the hype for expensive speaker wire?

Right on, Hilde, MC, Nonoise.
We are dealing with abstractions. Abstractions are abstract because they defy concrete explanations. We should welcome and commend the contributions made by the righteous electricians to our understanding of cables, switches, fuses and all the other "snake-oil" we enjoy at sometimes extraordinary prices.
Please, will one of them prove empirically that all cables are the same.
