How good are these.....?

[Beckman]

Which cables have you listened to in order to make such a statement?

Please explain to me the physics behind hi-end cables/interconnects. All it has to do is transmit a 20 to 20kHz signal a few feet. CAT5 cables have to transmit signals on the order of Megahertz hundreds of feet and CAT5 cable onlt costs .08
per foot. Explain to me how one can improve the sound quality by upgrading cables/interconnects when the signal is not distorted or attenuated an audible amount (0.4 dB at 20kHz for 12 AWG zip cord) when using cheap 12 AWG zip cord or radioshack interconnects.

High end audio cables/interconnects are a GIMMICK.

There is NO science behind hi-end cables/interconnects or PROOF that there is an audible difference.

People just "think" they can hear a difference.

Hi-end cables are a placebo.

It doesn't take a special cable/interconnect to transmit audio signals.
