I can recall systems I had in the past, turn the volume up without playing anything and you would get mains hum, hiss and all sorts of audible rubbish. With the Devialet, turn the gain up and you get silence.
How much difference can EMF actually be making? Although it may very well be having an effect on humans for all I know.
And how can you wire a lamp out of phase? Or are you referring to inverter type dimmer switches? (Which can be very noisy). Edit - I do take the point about switching neutrals, this is actually very dangerous, but when a light is switched off you have almost infinite resistance in the circuit either way, so surely no EMF here?
