In fact, I would venture to say that most of the "accepted" audio imporvements are probably just as imaginary. For example, many people claim that they can hear a difference between WBT or Cardas connectors (binding posts and RCA plugs) vs. regular Radio Shack types. Also, many people claim to hear a difference between different types of insulation.
I am willing to put down $10,000 cash on a challange of any double-blind scientifically organized listening test. If the listener can identify WBT posts versus 50 cent posts from Radio Shack in a double-blind listening test, then I will pay this person $10,000.
Anyone care to accept the challenge?
So, please stop trashing the CLC when you people accept other ridiculous accessories.
