Yes, you absolutely must have aftermarket cords. There is a huge difference from stock cords. You will hear more weight and bass, a larger, more defined soundstage, and all instrumental timbres will be affected. On stock cords, you will have a strangulated, thin, dead, airless & constricted sound.
On my JC's, I have used AZ Tsunami cords & BMI Sharks, both of which are great matches. I have used others as well, but they did not deliver the same results.
