Upgrading IEC Inlet advice

I am thinking about upgrading the IEC inlets of my various components (Luxman d-06 cdp, Accustic Arts Power 1 int amp, PS Audio P3 ac regenerator) and was hoping I could hear from folks who have done this upgrade. What things should I consider, what things should I watch out for, etc. I highly doubt it is a simple drop in replacement as it seems there is no standard IEC inlet size. This would mean that I may have to take a Dremel to my components if the IEC cutout needs to opened up a bit.

Anyway, any advice is appreciated.
