Thank you for this - I’m not educated in this area but the thing that always stand out to me on cables, ESPECIALLY power cables is that the power going all the way from the station, multiple transformers, through your breaker, housing wire, outlet, then to your cable. While using a bad material and shielded cable could definitely introduce some bad stuff, no quality of cable from the outlet to your device is going to remove any mess generated from ALLLL those stages before it.

I’ve not heard of a power conditioner before but looking it up that would make the most sense to me.
