I have an older model Prelude power cord. Its a good quality and good looking cable. I cant hear any difference with it. I didnt expect to. Its sheilded. Thats a plus. It was cheap though. If you can get something like that for really cheap they are good cables. What else is there to say.
This is the wrong forum to ask opinions on esoteric cables. I cant think of anyone here who will tell you anything other than your wasting your money.
Personally I would spend enough to get something good quality but not near what the statement line goes for.
