JPS Labs versus Audio Quest (Megasam?)

How would a person rate JPS Labs cables (speaker or interconnects) to Audio Quest? I have AQ, but have heard good things about JPS. I've heard that AQ will "simmer down" a bright system ... is this true? If so, what if one doesn't have a bright system ... does that mean they don't want AQ cables? I've heard that JPS is very neutral. Any help would be greatly appreciated. I'm running AQ Midnight 2 speaker cables currently but have been thinking of changing to JPS. Thanks Much.
