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

Excellent points, and well said Byron. Also want to mention that buying and selling used power cords on Audiogon is very inexpensive, and they will be going on $18,000.00 mono blocks. Clearly worth finding out if power cords can improve the sound for the owner.

I tend to believe that pass amps don't need expensive cords. I'm good with the original (for now). Based on other reviews, another good cord that matches pass labs is the transparent premium power link which is only $500 a piece. I agree with Byron that pass amp has robust power supplies. Not only that, it can also drive a wide range of floor standing speakers. This amp will stay w/ me for years.

There is only one

-----> The Mother Of All Powercords

Syntax, that is one heck of a powercord indeed. The price tag is the mother of all pricetags too! I must say that pic made me think "if I win the lottery..."!

Syntax,
The irony is in most power cables if you remove the megabuck cable plugs and inlet and hardwire the cable into the equipment you can halve the cost and increase the sound quality. It cracks me up to see audiophiles buying jewellery type connectors, when if they simply bypassed them ...
Same with earthing, well implemented single earth path for the whole system can yield significant improvements in noise floor and transparency. Again it cracks me up to see megabuck systems compromised by having multiple power feeds and hence multiple grounding points that inevitably increase the likelihood of hum etc.
A little housekeeping goes a long way.
