I am quite puzzled by this. I just tested with 98dB speakers, and 12 mV ac or so as a background hum is almost intolerable to my ears. There must indeed surely be some mistake in the measurements. I cannot believe anyone could put up with that level of background hum in a supposedly high fidelity amplifier.
Even 1 or 2 mV is still enough to be irritating, I think. There is really no excuse for having any perceptible level of hum in an amplifier. And claims that killing the hum necessarily kills the music are really just hogwash. If an amplifier needs added mains hum in order to make it sound good, then there is something fundamentally wrong with its design or implementation.
