FERRARI, good link.
I have a Pass Labs amplifier and I'll be honest, I have not found earth shattering improvements with an aftermarket power cord with this amp(power cords tried were up to $700).
However, it is not the case with ALL amplifiers and other components. I think the differences you hear or don't hear with upgraded power cords on the amps depend on the power supply design and quality.
For example, a $6 Volex power cord sounds excellent. A Shunyata Taipan Alpha Helix cord does sound just a bit better, but not what you would call a huge difference.
I had several McCormack amps, where an upgraded power cord always made bigger difference than I experienced with the Pass Labs amp. So I don't think that any general rule applies here.
It has to be determined on a specific amp with a specific power cable only by trying.
That being said, I know someone with a Primaluna integrated using a Shunyata Taipan Alpha cord and says it is a very nice improvement.
