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.

No - never heard a thing come through the mains. If I started hearing
stuff now, I wouldn't be buying mains filters - I'd be fixing the
wiring.
