Power cord supplied with Luxman L-509X Integrated Amp

"Not putting a nice power cord in your very nice Integrated amp is a crime. You are leaving a lot on the table to extract the best performance from it...."

I’ve tried various audiophile power cables on my Bryston Integrated Amp and it doesn’t care what I feed it with. Bryston and Pass have long maintained that there is NO benefit in replacing the stock power cables with expensive "boutique" ones and, based on my experience, they’re right.

I've never had an expensive piece of hifi that DIDN'T come with a cheap looking generic power cord.  Same goes for interconnects.  BYOC (Bring Your Own Cable) is expected.

Oh boy… Audio Science Review militia has embarked 

What is physically happening in the cable that produces a better sound out of the system?

And can it all be measured?
