In my opinion installing an IEC on vintage equipment is a mistake and it does devalue the equipment. I personally would not buy a vintage amplifier with an IEC modification. Besides, the amplifier was voiced with the existing power cord.
In fact, at one time I owned two sets of Quicksilver Silver 90's. One set had the original power cord and the other an IEC with an aftermarket cord. Guess which one sounded better. The one with the stock power cord.
With vintage equipment it is more important to make sure the polarity is correct when you plug it into the wall outlet.
