Shep,
Check out the following device from Music Direct:
http://www.musicdirect.com/product/73367It is a moulded adapter that goes from an IEC to a Standard three prong electric socket. Its stated use is for burning in a new power cable. You put the adapter on the IEC en of your power cable and then plug a lamp into it and use it as an extension cord fro the lamp. I am not sure how this would be different that just say putting your CDP on repeat and playing it for several days with the amp turned off (except than maybe you avoid the wear and tear on your component), but I would not use it that way anyhow.
I have have several audio buddies who have used this adapter to add a high quality power cord to a component that has it's cord hard wired. Think of it as an "after cord" instead of a replacement cord. They all seem to be very happy with the results.
I guess this kind of makes sense when you give it some thought. When you replace a stock power cord you add 3 feet of high quality power cable at the end of 50 miles or so of crappy transmission lines and house wiring and it makes a big difference. Well when you go the after cord route you are adding the same power cord to the same 50 mile plus an extra few feet (the stock zip wire) of crappy cabling, so it doesn't surprise me that it would work. I am going to order one of these for myself and give it a try. I'll let you know how it turns out.
Now would it sound better if you hard wired the new cord to the unit? Quite possibly, but the same can be said of using that cord via an IEC connector. This adapter can also be used to evaluate various power cable options and then whenyou settle in on a winner you can cut the IEC end off and hard wire it to your component.
As I am writing this I realized that an adapter with a US electrical termination won't do you any good, but maybe if you search the web you will be able to find a similar unit with an EU friendly connection.
Hey here is a radical thought... perhaps one of Alan Maher's CBF's on the stock zip cord might have a similar effect to a power cord upgrade????? I might have to try that one myself, what the heck, it's only $25. (the only downside to trying is that it will take 4 weeks to settle in so we could figure out if it worked and the wait would drive me nuts, not unlike being part of the FedEx "world tour."
