There seems to be a lot of misunderstanding about power cords. I will simplify it, and no doubt someone will pick me up as a result, but here goes. The crappy TPC in your wall, and the crappy stuff going way back to your power company has one big benefit - it has low resistance. The downside is that it picks up and even generates noise, some of which gets through into the music signal. A short length of good power cord between the wall and your components is a good thing because, many basic cords become a resistive/reactive bottleneck, and because a good cord will be designed to provide a judicious degree of conditioning - hence getting rid of a lot of the noise. Both of these concepts make a nonsense of the protests that a short piece of power cord cannot be relevant in the context of miles of crappy TPC back to the power company. The conditioning effect of a power cord can be much more successful than a power conditioner for a variety of reasons that space does not allow me to outline. Suffice to say, while a conditioner can do the conditioning job, it unfortunately introduces problems in and of itself. Furthermore, power cords sound different from each other even without a ground. Apart from suggesting you listen, you might also consider that conditioners also operate between phase and neutral. Adding an IEC adaptor (as is being suggested above) increases the connections after the expensive power cable, thereby letting back in more of what you tried to remove with the expensive cord. It does not defeat the beneficial effects of a good power cord, but you will get better results by putting in the large IEC receptacle - but you must weigh this up with warranty/resale issues for yourself.
