Nordost's list is taken from Linn, which from the very beginning said the source is the most important element, i;e turntable, arm, cartridge, phono amp etc.
I am surprised so many believe power cables are the most important. I have said this before but the cable you can pay $25,000 for and more is just the last 6 feet of 10 miles or more of cabling that comes from the power station to your wall socket. What about the other 9 miles and 5,274 feet? Power conditioners are different because they interface actively with the power.
