Well, I just installed the Dart into my audio system after running it on my basement refrigerator for about 200 hours. I installed it on my JL CR-1 crossover since that unit affects both main amps and subwoofers.
First impression: It definitely has a different sound perspective than my previous DIY cable. To me thus far it sounds like there is more upper midrange presence. So, it may take a while for me to get a handle on the sound. And, if I prefer it or not.
