Frank--I think you should look at the issue of power cords as an opportunity. In the other thread on power cords you stated that the PC is just an extension of the transformer.
That being the case, you could market a high-end 'extension cord' that connects on one end to the OEM cord and at the other to the wall socket. Those so inclined could even snip off most of the OEM cord, install the plug of their choice, and connect the extension cord to the shortened hard-wired cord.
Of course, anyone with e ...
It isn't quite that easy. Either they change the tooling for the chassis, or they modify each chassis by hand. It isn't much fun to nibble out a hole...
It could also open AVA up to problems with liability. Right now there's a dedicated power cord, for use in N America. It's 2-pin, and is polarized if I remember.
Ok, so replace that with an IEC socket. AVA now has zero control over how power is wired. People can screw up and connect the pins wrong; even use uninsulated wire.

Somebody in another country who doesn't know (and perhaps can't read the markings on the unit - in english) sticks on a standard IEC power cord for their country. Without an export xformer option, that could cause some real problems.
At least if you yourself put in an IEC socket, or hardwire a different cord in, it's your action. AVA can't be blamed if you modify the equipment after purchase. They gave you a safe unit and you changed that yourself.
Having an IEC socket allows you to plug in whatever you feel like, and it's not as easy to argue that the unit was modifed by the owner just plugging in an unsafe cord.
In this time of plenty for attorneys, a manufacturer has to assume that their clients are idiots and idiot-proof their products - especially when there's a change of fire or electrocution.
Note that I didn't even get into whether swapping cords is worth it or not.
AVA doesn't make changes unless there's some benefit, and I don't see how this would be beneficial. It could well be detrimental instead.
