I have been most amazed by the differences among power cords.
I have some expensive cords here that came in stuff I had bought but the problem with the IEC power cords is the fact the are a slip on connection and that's a weakness that can cause cause micro arcing. It's a lot better to wrap and solder the end of the cords but what I did was put braided shielding over the cord and soldered the one end of it to the chassis and this way it will take any RF to ground in relation to the cord..You can also put inductive clamps on the cord that will take care of RF as Eli did on his cords.

That's the ideal, purist approach but it pretty much destroys any resale value, so I haven't gone there. Some IEC connectors (e.g., Furutech) seem to grip a lot better than the ones we used to have to deal with. But I'm not sure we gained much by going away from hard-wired PCs. After-market PC manufacturers would surely disagree.
No doubt because it's a money making scheme..Just simple logic tells us that a little 5ft section of cord couldn't dramatically change things because once you get past that 5ft of cord, you are back to the standard 12/2 house wiring.How are we supposed to overcome that?....If a cord supplies adequate voltage and current,its job is done.The only thing we can do is trap out RF and maybe digital noise that is all over the place and possibly make the cord to act as a filter by putting the shielding on it or the RF inductive filters and trapping out some of it..The only problem is,you would still have to trap out the RF and digital noise everywhere else from getting in the amp or preamp..The only way to do this is to build an amp or preamp with a good copper plated chassis and shielded signal wire and good power supply components.

"Simple logic" or no, power cords DO matter, at least for me. I didn't want to believe this for a long, long time. But now I put power cords right up there with interconnects and ahead of speaker cables, in their contribution to sonics and synergy. Power cords and CONNECTORS, that is, noting that if I can change the sound for the better (or worse) by switching connectors alone, there's something happening that simple logic doesn't account for. I've heard it too many times to start doubting now. And I have yet to try a power cord that cost more than $250 (I mostly make my own or reterminate existing ones). Been doing this for years.
Case in point. I think the Pangea PCs from Audio Advisor are great for the money. But I reterminated one pair of the original AC-14 (14 gauge) with Furutech ends and the difference -- and improvement -- was clear. Later I bought a pair of the supposedly improved AC-14SE version and damned if they didn't sound as good as my reterminated ones.
Second case in point: Half a dozen audiobuddies and I were listening to one guy's new CD player and finding it wanting. All of these guys (except me) are hard-core DIY people and one suggested changing the PC to a cord he had brought along. The difference was downright amazing and, yes, we switched back to the original cord at least 3 times because we were frankly incredulous. The "winner" was a Cardas but I don't remember the model. This single experience, approx. 6 years ago, pretty much made me not just a believer but a confirmed one.
But a soldered in power cord is going to be better than an IEC because you will not get the micro arcing you get with a slip on cord.Of course you need to put shielding on the cord to trap out RF and digital noise but,that takes some work..It can be done tho.
I have some nice power cords,and on the amp's I own that have IEC connectors,I heard no difference..I maybe need to try it on a preamp or CD player to get a better perspective.
