RE: I suppose "may" is the key word here

It sounds like your AM radio is rather insensitive or has been tuned to a strong station. Try tuning it to an unused frequency that is far on the dial from any strong local station and listen to the background noise with the computer powered down, powered up but idle and running various software. If you want to test the audio software and your DAC you can have it play music, provided the amp is turned off so noise from the speakers doesn't interfere with hearing the radio.

You are fortunate to have a DAC with good isolation. Others are less so. If you don't hear difference between bit perfect player software or computer tweaks, consider yourself lucky. And yes, there should be silence out of the speakers when playing silent portions of digital tracks. I can't imagine tolerating a DAC or amplifiers where this was not the case. Ditto for any other kind of noise such as hum or buzz. Note that electrical noise from the computers doesn't just add to the music, it also interacts with the music, thereby adding distortion.
