The only way to know is to try upgraded cords and decide if the difference you hear is worth the money. In my experience aftermarket cords can make a significant difference.
One way to experiment - as I did - is to contact The Cable Company and rent several for their 10-day trial. You can put the rental fee (5% of retail) toward a purchase of new or used cords. The other way is to buy used and resell on AudioGon as a way to sample differences
After trying several - SIlver Audio, Kimber, Harmonic Tech, DiMarzio - I found the JPS Labs cords to be head and shoulders above the others. But the only way to know is to try some yourself.
