Power Cable for DENON DVD-3930ci player

I just purchased HDMI cable from Blue Jean Cables and is wondering should I upgrade the power cord from a stock to a?
Will I see/hear a difference in higher quality in cables? I will have the player connected to a KURO plasma (50") - Any suggestion/recommendation would be greatly appreciated!

I used a Virtual Dynamics David 2.0 with the 3930ci in my H/T it was an improvement in dynamics and soundstage.
Thanks, I will look into that and also I will chekc into Ridge Stree Audio a/c cord..... How much did you pay for your cord?
You can find them used for around $200. The VD P/C's are forward(aggressive) cables!
