As one who can hear differences in interconnects, speaker cables and digital connections, let alone tube rolling...... OK, power cords not so much anymore after the Niagara install, ..... I probably don't have any links other than power cords that have not been shot out 8 to 10 times... tubes more than that.
It is what it is.............. I hear differences in everything including taking a picture on or off the wall.
