The secret sauce seems to be something called 'magnetic conduction' according to the website.
Rick does this mean these cables in some way use magnets? My past experiences of such cables using magnetic technology have been amazing to begin with, but then the sound deteriorates over time. I have had reports of others using magnetic power cables that had the same thing occur.
My theory is either the magnets start to wear out, or they start to magnetize the components causing a deleterious effect on the sound.
Im not saying High Fidelity Cables does this or even uses magnets, but I am wary none the less.
