Plasma Aftermarket Power Cord

I already have the power cord to use but don't know if it would be of any benefit or actually may cause problems with these units?The HD model was over a thousand dollars more and for my viewing distance of 10 feet i could not see that much of a difference when they were side by side in the store.The HD was better but for my budget i couldn't see going that route and the Panasonic EDTV looks fantastic.
If a better power cord will improve image quality even further without causing any problems i would certainly use it but wanted to ask the forum for advice.I have a VHAudio Flavor 1,2 and 4(non-gold) i could put on there as well as a Signal Magic power cord.The Flavor 4 is the best of the bunch for audio in my system.

Thanks folks-
yeah i was sitting at the local BB and watching the INHD channel that was showing shots of the carribean with the EDTV and the HDTV side by side and i was amazed regardless of which set i was looking at.The EDTV looked outstanding!!!Yes the HDTV looked a tad better but really i couldn't justify that much more money for that little of gain at this time and it is heads and shoulders above my prior 31" JVC CRT TV.
Thanks Stuespeed and Reubent as i think i did make a good choice after doing some extensive research on these plasmas the past few weeks.
I am purchasing the commercial model so it doesn't have all of those added features but it was also $600 less then the consumer model so i went with it.Getting the whole thing shipped with speakers and stand from DTVCity.com for $2269.Heck after seeing some of the threads about these tv's just one year ago these were up near 3k.So yes the prices are dropping and i think i got a good deal from a reliable vendor.

Guess i will just try some different cords then since it doesn't seem to be an issue that can damage anything.

Thanks again for all the input

Sorry for being remiss in checking back on this thread that i started.Well i never did swap out the power cord as i was affraid that a larger cord may actually slipout of the back of the unit since it plugs directly upward into the unit.The Panasonic has a locking sleeve for their stock cord so this does not happen but will not fit over my replacement cords that i would have tried.However i am running into the back of my Dezorel G2 line conditioner and things look great and it has not seemed to effect my audio performance(which also is all plugged into that unit) one bit.My soundstage is large and image quality is really great.Just didn't know how much better it could get and was wondering.Decided to look back at my past posts and saw that i didn't respond to some posts so sorry about that!
