Yes they do. Unbeliveable, huge difference.
I did not believe it myself until I tried to make a cheap DIY power cable.
it improved the sound a lot compared to the standard 2$ power cable.
That was 4-5 years ago. Since then, I built more than 20 of them.
The last cables were made with expensive materials, gold or silver plated OCC copper and Neotech plugs. They sound amazing.
It is definitely worth the money and it has brought a huge upgrade to my system.
Everyone should try for themselves and listen.
