Do try Audphile1's suggestion and also be sure the jumper is decent -- not the stuff that typically comes with the speaker. A short length of the Home Depot wire should do the trick since you had good experience with it.
If it still sounds worse, even after some burn-in, enjoy the Home Depot wire, sell the Audioquest and think of all the money you're saving!
