A better lamp cord for my stereo equipment?

A lot of space goes to the 14, 12, 10 gauge, monster-sized, plug in, power cables.  Rightfully so.   I have my favorite power cables in place on my amps and also on some of my source equipment. But, some of us have older pieces in our systems and many of these older pieces do not have the plug in, switchable cords. I have a few pieces that were built with the old, permanent, lamp cords.
I've alwys wondered about those cords, but I never see any posts about them. Service people don't like the idea of drilling out the cord opening in older equipment to allow for thicker gauge wires, so we seem to be stuck with similar sized cords.
Have any of you ever upgraded/replaced your cords on older equipment?  Do you know of a better grade of lamp cord out there?  Would just replacing the plug help?

OK    Uncle, uncle!

I just had some great sucess with two cord upgrades for my Bryston amps and I thought my good, 60 year old, McIntosh C-20 preamps and a few of my old signal processors might also benefit from a cord upgrade, if there was a new type of cord out there that might provide an improvement.  
I have to admit I'm a bit befuddled by the fact that the cords have a, "Do not touch" policy attached to them (legal-wise), when I've had capacitors replaced in the power supply in many of my components.
Nevertheless, I was hoping someone would say, "Try this new, oxygen-free copper plus silver, stranded, twisted, cooked, directional cord from So-and-so Supply Co.
Since there doesn't seem that anybody has ever built a better lamp cord, and techs might not be willing to replace the cord anyway; this idea will just have to go on the Not Feasible pile.
Thanks for all of the responses.

I have added an IEC receptacle to several of my older components with great success! It is fairly easy, and the vast array of powercord tech is then at your dispense. As a matter of fact most of the gear was mid fi and it responded very well. Just order a couple of receptacles, get a dremel tool with some cutoff disc. Make a pattern for the opening , mark tht rear panel and take your time. It usually takes me about 1.5 hours, then  used canned air to clean out debris and connect. This process has now been made easier with the new IEC receptacles which have screw connections. Give it a try it is WELL WORTH the time and the older powercords are very inexpensive here on Audiogon.

Installed a 20 amp (C20) IEC on a Krell TAS so I could use a Shunyata PC.
Not sure if it sounds any better but easy enough to do. Local audio repair guy wouldn't touch it. Now I know why.

Or possibly he didn't have the confidence in installing the IEC power inlet. What if in the process of cutting the hole for the IEC inlet he screwed something up? How many "repair guys" cut holes in the outside panels of audio equipment?

Did the "repair guy" specifically tell you he was prohibited from installing the IEC power inlet?
