I agree to use your best cable to the power conditioner / distributor. As previous posters have said, it is best to experiment since the response is component dependent. And as suggested above, use smaller gage cables on low power components and larger gage for high power components such as amps.
Best Power Cable Component Hierarchy
Greetings,
A popular consensus is that your best power cable should be from the wall to the power conditioner. After that placement, what components are most affected by power cabling (Amp, Preamp, Dac)? Moreso, in what order should successive cabling be placed?
