Power Cord Question

I appreciate your responses. Very informative. I won an auction for power cords here on Audiogon but thought it may be a waste of money to upgrade two prong power cords with the three prong type. My NAD C372 integrated amp has a two prong receptacle on the rear panel but the new power cords use a three prong female ends, thus my question. I find it strange that my audio components use detachable power cords with two prong receptacles: NAD C372 intagrated-amp, Marantz CC4001 CD changer and OPPO DV980H, but my LG LCD TV uses a three prong receptacle for its detachable power cord. I guess that shows how little I know about the electronics end of this hobby.

Please do as Waveman suggests and get the adapters. That way, as you move up the ladder componentwise, you'll have the correct three prong power cords.

I think what you're looking at is a C7 socket/connector. (The 3-prong is called an IEC.) A few cable companies make cords terminated with a C7--PS Audio is one example (though I'm not necessarily endorsing that product). Visit a site like Audio Advisor and see if the photos match what's on the back of your units.

Kudos to Twoleftears and Musicnoise. Here is another info link > http://en.wikipedia.org/wiki/IEC_connector As the right honorable Krell_Man suggests, better power cords can improve your results. And don't forget conditioning. The fact that you have already purchased upgraded power cords indicates you are far more knowledgeable than you give yourself credit for. Good listening.........

These adapters may be what you need.
