Hi everyone,
I've been doing a little online research. The name that seems to come across here on audiogon regarding power conditioners is Shunyata, while @elizabeth and I talk Furman, especially due to cost.
I wanted to point out that what these two brands have in common is inductance. Coils. Coils in series with the outputs.
Furman and others who have licensed series mode surge protectors use great big coils to slow down surges long enough to let the surge protector react. Furman calls it SMP, but the tech has also been licensed to PS Audio and other makers. Essentially this is a low pass filter, which starts working at 3 kHz. That's way down in the audible range.
It's clear from pics of Shunyata's insides that they are using great big coils too. Why? Well, you can make a coil with high inductance, and low resistance at AC.
Anyway, my point is, these two brands share this basic principle. If you want to supplement a Shunyata by taking digital streaming outside of it (routers, wifi, etc) consider this super inexpensive Furman strip:

The PS Audio strip which uses series suppression is here:

Best,
