What is the best power cord for pass labs xa100.5?

STEALTH V10 amp cord.

There is no doubt in my mind Nelson Pass selects the best power cord for his products.

That was a joke, right? All high end manufacturers bundle appropriately robust but otherwise very basic and inexpensive cords with their gear. They do this because they know the market demands detachable power cords and consumers want to experiment, so why should they increase the cost of goods only to have everybody second guess their choices. Likewise for feet, fuses, etc.

If a manufacturer felt strongly about a particular cord, they should hard-wire it. The chassis IEC inlet has got to be a meaningful sonic compromise, but somehow we are all okay with it.

I'm not ok with it and most manufacturers were not ok with it either, but the reviewers, dealers and eventually the market demanded it. The price of a power cord has nothing to do with its ability to improve the sound. Do you really think a manufacturer would provide a power cord they know is inappropriate? Aftermarket power cords are just another snake oil variable to muck up the sound in my opinion. Too much emphasis is placed on air, openess and a bunch of other things that have nothing to do with music. That is why we have people on this forum telling us how much better their system sounds than live music. What a pathetic statement!

Be careful with aftermarket power cords on Pass amps. On my Aleph 0s the iec female is inside of 10mm of milled steel. The heavy gauge stock power cord fits perfectly. No after marker connection I have tried fits correctly into this deep recess. I found this out the hard way when one of them made poor contact and shorted the iec and power thermistor.
