I have a Quad 909 with an on/off switch that can sometimes be noisy when turned off. Quite often a sharp popping sound is made when the amp is switched off and I am concerned this could damage the speakers (is it caused by DC?).
The noise can be avoided by turning the amp off at the mains plug socket. The socket is switched and flicking the switch off causes no such noise. Given that the 909 has no 'soft start/finish' mechanism, is it OK to turn the amp off this way?
I intend to send the amp off to Quad for maintenance at some point.
