I had AQ Monsoons and upgraded to the Anti-Cables. Much lower sound floor.
After burning everything in through the Anti-Cable power cords and a AQ Niagara 1200, I had buyers remorse. I briefly unplugged everything and substituted decent shielded power cords. And then I listened. The difference was immediate and blatant. All of the noise was back. The difference is sort of like listening to a car while it is sitting in your driveway and then listening to the same music while driving.
Anyway, I immediately replugged in all of the Anti-Cables and the AQ 1200.
Anti-Cables are good stuff, I also run some of their interconnects and would say that they are at least equal to or superior to the AQ Earths that I was running.
