Which power cords have high resolutions and separation??

That’s an interesting question. I found that power conditioners and cables provide black noise free background to the music. In doing so, it allows, along with interconnects, your components to be heard. For me, to do this to a high degree required that I spend more money on power than any other one component of my system. I’m guessing that the biggest bang for the money would be a single dedicated circuit and whatever suggestions come via this thread.
