“The point I want to make here is that high-end audio equipment will likely not have a lot of noise peaks because they already have noise-reducing circuitry. However, they may very well have some high-frequency noise that makes its way into the signal. The origin of this high-frequency noise is not known. It could be coming from anywhere in your home, including appliances, Wi-Fi router, etc. Everything these days seems to have Wi-Fi capability, so this noise can be in the megahertz range.

Removing high-frequency noise is a matter of your own priorities. If you want to maintain the purest signal possible, then adding a high-quality power conditioner is desirable. The Clarus Concerto is certainly of that category.”
