Digital front-end p/c recommendations?

I am looking for recommendations of a quality power cord to use with a Wadia 830. I will be running this straight into a WattGate outlet, not into a power-conditioner. I am thinking I could go for something which sells for up to around $400 used. By the way, I cannot afford to buy yet, so offers of sale must be respectfully declined. Thanks.
Whale Elite is alot of power cord for the money.
Yes: ESP essence, $500 new, less for "demo"... you can buy from in LA. Very good sounding cord and a big improvement to the stock cord on my EAD Ultradisc 2000.
I have been listening to the Tekline cords and although I have not seen alot on it (my dealer friend sells this) they sound very good. Well made and all the ones I've seen have the wattagate ends.
I second the BMI Whale or a Shunyata Black Mamba.
I'm using the Shunyata Black Mambas on my Transport and DAC with excellent results. I also tried the synergistic and PC audio, but I find the BMs give the blackest background.
