Nad 2600 makes a noise through the left speakers when turning on and a popping noise when turning off . My klipsch sub sw12-2 has a humming noise through the driver when turned on , I can feel the woofer vibrate also , and it gets worse as I turn the level knob up . I'm more concerned About my nad than the sub . Any help would be appreciated .
