A little History lesson on, "High- End" cables:


Inquiring minds might want to know, how the High-End cable market all got started.  Expiring minds?   Well......   (http://www.theabsolutesound.com/articles/a-short-history-of-high-end-cables/)

How (really) much better can a 25000.00 dollar pair sound than a 20000.00 dollar pair?

 Such a great spoof. However, it captures the truth so well. High end cable companies are perfectly setup to capitalize on subjective, facts. Like fashion, cable companies will continue to improve their wire. Cables don't wear out as fast as other components, so the science (?) will continue to support the latest and greatest new items. Perhaps a better upgrade than very expensive cable, check out the  Blackbody Ambient Field Conditioner. 
If you calculate the resistance of typical speaker cables at DC vs 20,000 Hz, for 2 meters of 8 gauge wire is 0.008 Ohms for DC and 0.016 Ohms for the skin effect at 20,000 Hz. Put this in series with a 4 Ohm DC resistance Magnepan speaker and compare the total impedance. Skin effect accounts for less than 0.02 dB at higher frequencies than anyone can hear. Therefore, if a cable company advertises by claiming to correct for skin effect: litz construction or flat ribbon cables, that should discredit them in general.
PS. Don't feel bad, nonoise, I just saw an advertisement for tungsten innerconnect cables claiming crazier than what you just lampooned.
