What AC Power Cord sounds best?


I'm looking to upgrade my power cords. I currently have 4 Synergistic Research AC Master Couplers in my system. They sound great but I understand there are some others out there with a quiter background, better bass, increase resolution, etc. Please let me know of your experiences with the 'really good stuff'. Thanks!

MUST READ the review of the Powersnakes AC cords, by Grant Samuelson, now archived on soundstage.com. Another possibility for "next generation" AC cords is Luxor's Custom Power Cords.
After auditioning many of the best power cords (PC's), including ESP, Electraglide, Cardas, Synergistic, Kimber, etc., I read the Soundstage! (on line mag) review of the Shunyata PowerSnakes by Grant Samuelsen. I followed up by contacting Grant, who is probably one of the most experienced power cord reviewers around. At his suggestion I contacted the Shunyata CEO, Caelin Gabriel, who has made power delivery his life's work. In summary, I purchased 3 PowerSnake Black Mambas (the medium priced PC), along with 2 WATTaGATE audio grade wall outlets. At Mr. Gabriel's suggestion, I removed my line conditioner and ran all 3 PC's directly into the wall. The combination was the most significant upgrade to my system since a major interconnect and speaker cable improvement a couple of years ago. I'll spare you the usual audiogeek ramblings, but just let me say that my system went from sounding like an outstanding hi fi, to as close to live music as I have ever been. The soundstaging, holographic immage, bass impact, overall dynamics, separation of instruments (there I go rambling, but I couldn't help myself) were monumental. I cannot recommend these wonderful power cords highly enough. My only regret is that for now, I couldn't afford the top of the line King Cobras, but at least I have reason to live!!!!! Read Grant's review, contact Brian Kelly at www.HelloHiFi.com and arrange to audition some PowerSnakes in your home - I know that you will be snakebitten like the rest of us who have tried them. Happy Listening
Has anyone had experience with the HARMONIC TECHNOLOGY AC-11 power cords. I`m thinking of purchasing this cable for my AYRE V3 power amp and WADIA 830 cd player. Any help would be greatly appreciated.
OK, now you are think this is crazy, but know something, it is absolutely true. The Shunyata King Cobra is best by a mile. No I don't work for them, they don't even know me. Not only did the King create better dynamics, a more "solid and definitive " soundstage, even the TV reception got much improved. The colors got brighter, less fuzz, and the images got sharper. Now remember the TV does NOT use the King Cobra, the TV has it's own outlet across the room. It has nothing to do with the stereo. The KC is a little expensive, but if you purchase it, I doubt that you would return it.
I have the Electraglide Fatboy for my amplifier (BAT VK-60). The best I have tried (so far).
