Cables don’t burn in. Audio components do.
Cables cannot transform a good system into an amazing one...unless you’re using the cables as a tone control. And of course, if your perceptions are in line with what you want to hear. Then you will be happy.
Cables shouldn’t really have a "sound" including speaker cables and interconnects.
However, using low AWG power cables can improve depth and clarity.
Monoprice makes some good ones. Rated at up to 1625w or more.
Be careful in navigating the snake oil out there. Also, a cable cannot create distortion. (Audioquest cables claim to solve this nonexistent problem)
