There have been some big improvements in power cords in the last couple decades and a lot in the last few years. Find a way to borrow an Audio Quest Storm series power cord. Then you can move it from component to component to get a feel for the difference you will get. Start with the a,p. It is likely the difference will be striking.
Older Power Cables
In my current system, I have three older moderately expensive power cables: 2 from PS Audio purchased about 24 years ago for $600 used and one MIT Zip Cord II purchased new. I was just wondering what will differences will I likely be able to "hear" by replacing them with some of the newer power cords that is currently being market.
