Here's a controversial (yet undeniable) statement. I added after market power cords to my reciever, subwoofer, and DVD player and each and every one of them made a difference in sound. In a nutshell I now have added bass (on sub and all speakers). And the other biggest thing was the sound tightened up. I got a second, third and fourth opinion on this...and all agreed when I did an A/B. For goodness sakes people...even MY MOTHER noticed a difference!

I just wanted to post this as a note to all who have the ability to upgrade their power cord to highly consider it. It's a cheap way to make a big sound difference. All three cost under $300...and one of them was 20 feet long (subwoofer).

If you have any questions feel free to ask.

How long did it take for them to break in?

He recommended 50-100 hours, and that's what I have on them.

That is an affordable upgrade..parts express maybe? I am all for tweeking and have had positive undeniable results too. Cheaper than buying all new equipment and keeps me busy.

I don't think you're crazy.

I have 3 Yamaha M80 2 channel amps and have replaced the OEM power cord on one with a heavy duty power cord and hospital grade plug (the rest to follow), same for the Ah! tube output CDP which now has a HD power cord hot rodded from the manufacturer. Folks who have bought the Panasonic XR series digitally amplified receivers have noted the improvement in sound quality from adding an HD power cord.

If your mom has heard the difference, who could argue with you?

I am not surprised. My friend recommended one for my Mits RPTV and the difference was immediately noticeable.

Anyone have an idea why this may be? Same principles as cables and interconnects? I've seen this type of statement in a few forums, and many have said they heard no difference between generic 12ga wire and $50/ft 12ga wire, but heard an immediate diffence after upgrading the power cords. I would like to hear more on the subject, if anyone cares to throw their 2 bits in.

whered you guys buy your power cords from?

Mark, the power cord replacement thing is still another audio myth which has no factual basis. The power has traveled miles from where it was generated and possibly a hundred feet through house wiring before it has run the gauntlet of the last 5-6 feet between the wall and the component. Standard power cords are ample to deliver over a thousand watts AC to more demanding devices(e.g hair dryers, hotplates)than audio components. The transformer, rectifier and filter capacitors in the power supply section of receivers then deliver clean DC to the amplifier section.

John, I absolutely agree with you. Having said that, I'm crawling into my foxhole. We haven't had a good "my copper is better than your copper" food fight for quite awhile.
