I find the better the equipment, the MORE that equipment responds well to a better power cord, better wall AC duplex.
Back when I had $2000 a pop electronics, I could barely tell the differences in power cords. When I jumped to $5000 a pop for equipment, and added a $3500 power conditioner, it became easier to hear the differences.
Now with a $14,000 pair of speakers, and a lot of AC improvements, I can hear the change of moving one power cord plug from a Gold plated Furutech GTX to the Rhodium one.
This is the difference of actual experience instead of fantasy theory, and the failure to realize: "Gee if I can't hear it, no one can" is not true.
