Oppo 980H - Power Cable Upgrade

Has anyone upgraded the flimsy stock ac cable for their Oppo player? If so, are you experiencing significant positive results? Please describe.

AC brand recommendations are welcome. I was in particular thinking of a VH Audio Flavor 3 (two-pronged input).
the VH is a good choice in general - you probably could not do better for the money...
I use a LessLoss PC into Audience AR6 and it has made a significant difference from stock PC. On CD's, sounds like a $2500 player.
