When do the new Atmasphere Class D come out?

Forgot to ask, is thert a coaxial TV connection anywhere in this system? If so, disconnect it as an experiment.

@gdnrbob
You may have DC on the line. That produces more of a buzz than a hum.

Try turning off all other electrical circuits in the house and see if it goes away. Fancy light systems like dimmable LEDs or flourescents can do this too.
