RW, you are right. I am totally with you.
If all these magic cables are superior to the internal wire of pre-amplifier or amplifier, why pre-amplifier or amplifier designers don't upgrade the internal wire to these magic cables?
I have a friend who works in the luxury goods / fashion industry. One time he was in the high ranked position at PRADA. He admits that people do pay a LOT for visual pleasure and touching enjoyment and people are willing to pay that much for their psychological satisfaction.
I pay a lot for my audio equipment to enhance my listening delight. The EDGE amplifier and Counterpoint SA-11 pre-amplifier I possess, they all have high price tags. Also I was one of the earlier Beta testers of Stealth’s cable more than 10 years ago. But I just can not justify myself to pay for the super expensive cables from Purist Audio Design. By the information Purist Audio Design provided, the Dominus cable is cryoed and stranded multi-gauge alloy in 18 AWG with special shielding. 18 AWG! My current cable is pure 6N silver in 16AWG at much realistic price. By my calculation, the cross section of 16AWG cable is more than 2.5 times of the cross section of 18AWG cable, what kind of technology can surpass these fundamental differences in Physics? Until more detail information is provided, I am still in the non-believer camp.
