Try this.

My home computer is in a different room and on a different circuit than my audio system. When I turn off the computer, the audio system sounds better. And my system is already tweaked out with good cabling and power conditioners. Even the LPS for my modem/router has a power conditioner on it.

The next experiment was to keep the computer on - but, temporarily disconnect the WiFi connection - via the control app. The results were almost as good as turning off the computer. I primarily stream Tidal. Since I rarely use the CD transport, I powered it down also. Again, another improvement.

It appears that digitius is quite proficient at polluting any & all circuits. If somebody else at home is watching Netflix or playing an online video game, it could be affecting the audio rig. YMMV
