Am I Nuts or What?

This goes against everything I thought to be true, but I compared sound quality of my Acoustic Energy ae2s with the stock wire jumper vs a pair of high quality Transparent and Apex jumpers and found the ol stock wire connector to be superior when using my non bi wired Yamamura m4000 or S/W Maestro speaker cables. This just seems to go against the grain of what should be a better setup, considering the cost of the Tranparent and Apex jumpers.
