The copper in your walls is 6 nines. 99.9999 pure copper. I've considered some aftermarket cords but only because the ones that come with components are sometimes a hassle to keep neat they're so long.
What do you think of this power cord?
Maze Audio is a family-owned company that states it hand-makes its cables in the US. There is a range of prices for power cables, but I was looking at this entry cable. I don’t see any mention of the metal used in the cables, but I don’t know if that is as crucial for power cables as for interconnects. I am interested in your opinions. Thanks.
