OPPO BDP-80 question

I have the 80. It uses the standard IEC 3 prong cord, not the C7. The cord will not matter in this circumstance, it will be the difference in players. If you use the HDMI output from the Oppo, it is very highly rated. I don't know if it will be better than the Sony on your display but the type of cord will not determine the difference between the two.

This should tell you what you need to know:

An upgraded cord on any of the Oppo players WILL yield sonic and visual improvement. Even a fairly economical cord upgrade will make a difference you can see and A/B test.
