2 pin power Chords?


Are there any of these made by reputable companies out there. I have seen adapters so you can use a three pin power chord but I just wanted to know if anyone makes a audiophile grade 2 pin power chord.

Audioquest NRG-1. I'm using one instead of the stock power cord that came with my Anthem TLP 1 preamp/tuner. Notice a slightly "smoother" top end in the sound. Considering it only cost me $100 (Canadian) brand new, not a huge amount to dish out for this little "tweak".
I chased down the brand I use. It's an HFT Silver. They only sell the Gold now and it's $149.00. These aer excellent two-pin P/C's.
