I'd have to agree. For me, the experience came when I first got into high-end hi-fi and was exposed to the "Cable Crusade." It's not a rational debate, it's a religous war. $8,000 for a cable? Not too bad - the Kimber Select Black Pearl gets up to about $18,000 or so for a long speaker cable.

I started with .50/ft 14-gauge stranded cable, and started borrowing/begging higher-end cables until I could not hear any difference between them, whereupon I decided I had reached the curve in price-performance, and just stopped. Some of the differences I thought would be obvious were non-existent, and some that I thought I'd never hear, I actually did. My total system is around $20k, and the cables were all less than $120 - and those were long speaker cables. Most were WAY less than that.
