It is all relative, fortunately.
If you have $30k invested in Amps, Pre-amps and DVD/CD players, then you want an associated cable to connect the equipment.
Otherwise, you won't hear the difference.
I'm one of those people that have the high-priced equipment, and have convinced my self that the higher priced cable is needed. However, for years I also revelled in mid-fi, and I equally enjoyed it. The only thing that changed is my ability to afford the more expensive.
