Question for all Esoteric owners with clocks .....

.....I have asked this before but never received a response that answered my question, so, I will try it again. Does, upgrading the BNC cables to the Esoteric clocks have an improvement on the overall sound. Now, the stock cords are just that, the stock cords ....but would a $500 BNC cable improve the sound ......so, if yes, then would going to a $1,000 BNC cable be even better ???? You see what I am trying to ask......if there is an improvement over the stock great, but how far should you go on these cords to the clocks ???? Thank you in advance
