Let's find ways to minimize electromagnetic radiation from power amplifiers.

class D amps emit electromagnetic radiation at PWM frequencies.
Many switch mode power supplies don't have dirty electricity suppression measures, so they can be quite dirty.

I don't think buying class AB amp with a linear power supply is enough to minimize electromagnetic radiation.

A power amplifier can emit electromagnetic radiation at audio frequencies( that humans hear with ears) and other unknown frequencies.
Shielded audio cables help, but that's not enough.
I just don't know how badly power amplifiers emit electromagnetic radiation below 100khz.

Can Esmog Spion (5G) convert electromagnetic radiation below 100khz into audio reliably?
Has anyone measured power amplifiers with Esmog Spion (5G)?

How can I minimize EMF from a power amplifier?
