Power cable upgrade for ARC

A friend has just gone to the mid level Transparent on his Ref 5 and likes it. They are avalable in 20 amp versions. Paragon has a bunch of factory recertified ones at about half price [list $1000] and may still have some.I bought 8 of them so I like them; replaced a mixture of other good cables. See my other threads for more on this.I would do the amp first from my own experence but no way to be really certain without trying it yourself.

I have though many times about putting an IEC plug into the chassis of my ARC gear.
The issue is I am too lazy to go through the complex hassle, since no good and not expensive IEC hole punch is available.
Then also taking apart some of the power supply to get at the spot, etc.

I have thought about just doing an at chassis pigtail mod, but I do not want to deface the ARC gear.

Hand cutting the rectangle for the IEC inlet is just a pain.

The solution would be an IEC designed to fit up against the existing hole, so it has a narrow circle opening into chassis, low profile body with nice design sticking out of chassis, and the usual two screws to locate.
Then all I would have to do is enlarge the current circular hole (easy) and add two small screw holes.
SOMEBODY make this up and sell them? Thanks....

I understood that the 110 at least used detachable AC cords. E. has taken your statement about dedicated A/C lines to mean that they are captive; the Ref 5 is removeable and I had assumed yours were as well so our advice is a little out of sync.
