Which power cords have high resolutions and separation??

@ebm 

Are you advocating jumping on cables as a new tweak?🤫

In my experience single core beats Litz everyday in terms of leading edge and impulse response. Think Acoustic Revive, Nordost. Also using an Add-Powr conditioner is a highly cost effective way of upgrading the supply side

Religious fervour. Might this actually depend on the resolution of the system used? Or do you simply know better?

Look at Akiko Audio line products before spending megabucks on a PC. Cleaning up the junction box and ground has bigger payoffs
