When you think about it though (referring to a comment earlier, about how if you hear a difference it's "all in your mind"), everything comes down to how it's comprehended by your brain. If you're using $4000 per interconnect RCAs, and in your mind it sounds better, than what's the difference? The sound is being interpreted by your mind, if it thinks that it sounds better than who's to argue with that.
I also seriously doubt anyone uses the cost of their RCAs to boost their ego, that's kinda ridiculious, there's so many more effective things to boost your ego over, like SPL and penis size //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif
