Turn your amplifier on, with no music playing and listen. Leave the

of it comes from the mains.
You've never heard things like a fridge splat etc which is mains borne? Of
course it depends on the design of the power supply in your amp, etc.
I've got a dedicated radial circuit with its own earth feeding my AV
equipment.

To e-mail, change noise into sound.
If folk happen to have mains borne fridge splats etc. surely employ RC
snubbers at the source (or if it really bad replace those burnt arcing
contacts) rather than going to the expense of filtering the mains for the AV
equipment. I borrowed some hi-fi branded mains filters - read expensive -
before I had a dedicated circuit and in every case they either made no
audible difference or they 'appeared' to be deleterious to the sound
(sighted evaluations of course).
