Cheap Powercords...worth the effort???

It takes a minimum of about 5 or 6 feet for the "filtering" factor of power cord to work.

I haven't tried a lot of different power cords to offer an experienced opinion, but I like what I hear with my Harmonic Technology power cord, and it really is at a very fair price for a good quality product. You can often find one for $100-125 at Audiogon. Perhaps when I get adventurous and have a little extra time I will try a few other brands, but I think that it would most likely give you an improvement in sound quality. I have seen so many opinions from some of the well informed members here that I have concluded that it is necessary to try a few different brands on your own system, allowing for synergy. Make sure you don't judge until you have run in a cable for 80-100 hours. Good luck.

Dievoyager, a power cord's design and materials can help eliminate RFI, therefore "conditioning" the power being supplied. Some people prefer to use high quality power cords without line conditioning. There are others at this site more skilled in the engineering and design aspects of power cords than I am, and I am sure they can offer a more detailed explanation.
