KWA Static
« on: 30 Nov 2013, 09:22 pm »
I have a LS100/KWA100 pair driving a pair of  Audio Physic Scorpio 25 speakers. Source is a Rega Apollo feeding a Mydac. System sounds amazing - great control over the 7 driver Scorpios, broad and deep sound stage...I (almost) could not be happier. When the system is at idle there is a static hum that comes out of both speakers. I have changed all cables, upgraded power cords, tried different outlets (the primary power outlet for my system is on a dedicated circuit with its own breaker). Working from the player back, I have powered up the system having removed each component. Alas, when just left with the KWA 100 as the sole component, the hum is still there. Positioning of the ground switch has no impact. To ensure it was not a speaker issue (again, the hum is balanced between both speakers) I connected my Creek A50 to the speakers - absolutely no back ground noise. A test with a Torus power conditioner, same hum. Help!
