Experiences With Costly Balanced XLR Interconnects Above $3,000

I think you would be well served by reading Audio Science Review. These cables are pure snake oil and there is no objective  scientific evidence that these exotic luxury cables sound different from a $50 cable. 

Blind testing is a great idea because when one pays a fortune for a cable one expects some marvelous change in sound that doesn't exist. That's psychology, and these cable tweaks are a fetish. When I read some reviewer of a component saying he hears different responses when using different cables I become skeptical because that is pure nonsense. Go to ASR and read Amir's excellent review of some crazy Nordost cable and also the one on a Wireworld USB cable. The Wireworld, despite extravagant manufacturer claims, sounds no different than an Amazon basic USB. I can see where people like certain badly rated speakers or prefer tubes to Class D or whatever because they like the sound they are getting which is certainly different. But this cable business is absolute rubbish, unless you are manufacturing and selling them. Some of these cables look very cool. but I'd rather enjoy the music and leave neurosis behind.
