I have found unshielded pc sound better with tube amps.
Copper power wall plugs have more realistic bite than silver.
Silver power wall plugs sound more organic on voices.
I made some unshielded power cables with copper wall plugs and silver iec - but they are not optimum for my digital equipment. AND, I am not convinced they are optimum for another tubeamp. It is quite frustrating to figure out what to use. I also have a sense that wattgate may sound a little bit better than furutech on both copper and silver.
Check out "power cable shootout" and good luck.
