What kind of power cord comes with expensive gear


I was just pondering power cords today . I started wondering what kind of power cords come with expensive gear . Over A few grand up to cost no object pieces . If they come with run of the mill black rubber shielding cords i can convince myself to never buy an aftermarket power cable again .

Any owners of said equipment or with knowledge on this subject please chime in .

With my experience of 2 products: Conrad Johnson Premier 350 and Lamm ML2.1 both comes with standard looking cords but voiced to match their products. They confirmed that those cords were custom ordered with purpose.
ARC has been using Sain PC's now for awhile.You can check out his website,excellent stuff,cheers,Bob
Most of the higher end gear I purchased came with beefy power cords but nothing special . Fine tuning the sound with cords is such a personal preference that suppling an expensive cord would be in most cases fruitless .
