@classicrockfan - I was agnostic about power cables before I actually did some experimentation. My point of view was “I don’t know enough about the science to have a strong pov on whether different power cables would make a difference.”
Now that I’ve experimented with a few quality cables, I believe they make a difference. That said, your system has to be resolving enough to hear what higher quality cables can make…
I think the cables that have made the most difference would be Kimber Kable Palladian PK10 and Cardas Clear Beyond XL. I bought them used… could not afford them new!
