Obviously, people think it makes a difference. Otherwise, why would so many businesses dedicated to custom power cord development and distribution be so successful? We can't all be wrong on this. I agree with Horchai. Your equipment configuration is critical. If you equate the $10 cord as the "supplied" cord for most equipment, then purchasing a custom power cord does have advantages. Suddenly, it's not the sacrifice component in the equipment production lifeline. I guess if I was making audiophile equipment and had to cut corners, the power cord would be an obvious choice. Just my $0.02.
