Lots of bad information going on in this thread. The differences between standard IEC cables and IEC cables from say
Shunyata Research are VERY real. Anything they make with their patented helix geometry is absolutely worth the money and they have the science and endorsements to prove it.
I demoed a pair on my Adam S3As and it was like a different speaker. My friends, family, and clients were all able to perceive the difference between the two cables. I now own a pair.
I don't expect anyone to believe it, so quit debating and demo some. For those of you who refuse to believe, thats fine too, those in the know will ALWAYS have an upper-hand.
BTW, Any of you guys should be able to get a local audiophile boutique to lend you a pair to demo in your studio for free, but BEWARE: I find that audiophile gear dealers are a lot like drug dealers... they get you hooked for free and then charge the fukk out of you.
