Finding a Power Cord that sounds great

There are so many Power cords out there it is mind boggling. I have tried quite a few of them. Here is what I have tried over the few years. JPS +, Kimber Kable Palladian, Cardas Golden reference, Shunyata Python Helix. They all had their pluses and minuses and I kept looking. Some I enjoyed more than others. I recently tried a BPT L9cT(advertised here on Audiogon) and was surprised at how good it was for such a reasonable price. Chris Hoff of BPT(great guy to work with by the way) made a special L9cT Power Cord with the new Furutech FI50 connectors recently. Wow! Now I thought this is something special. It imaged better that any of the other Power cords I had tried with a deeper and higher image than I had experienced before. It is still a fast cord with excellent transients and great bass but with a much bigger sound stage. Also the Furutech FI50's seem to give the sound a relaxed realistic character to instruments. Pianos especially sounded nice. I have heard the Furutech powerflux power cord was an excellent. It was slightly higher priced than what I wanted to pay for a power cord. It uses the F150 connectors. So trying the BPT cord with Fi50s was a nice find.
Anyone want to share their experiences with the best power cord they have used? I know some of this is system dependent. Has anyone tried a BPT power cord or a power cord with FI50 connectors? Just wanted to say I had a very good listening experience with BPT L9CT with Furutech FI50s.

I am using the new BPT powercord, and also the new BPT interconnect, to very nice effect in my system. Like Jrn, I recommend them. John
I was skeptical of power cords for years until I tried a Wireworld Aurora 5 squared. It made a significant improvement. I then tried a Cardas Golden Reference. It was no better and no worse. Just a lot more expensive.
I too was skeptical of power cords & then I thought "ok smarty, if that is the case then try it without one". I am amazed by the 'black backgrounds' & giant sense of 'space between the notes' that this change has made in my system, but I will probably revert back as I feel that there is a loss of dynamics.
I too was very skeptical about power cords improving the sound of my system. I found the cable company would lend me cords to try from there lending library without obligation to purchase. After several auditions, the Synergistic Research cords improved the sound far and above any others I had tried. They use a process called "Quantum Tunneling" that they claim produces 0 resistance in there products. The Hologram D cord on my CD player was particularly an eye opener. No affiliation but WOW what a difference
