Best Powersnake for ARC Tube Monoblocks

I recently got Viper v2s for my Pass Aleph 2 monos and I must say I am absolutely thrilled. I already had purchased a King Cobra for my Wadia CD player and was so impressed I got the Vipers for the amps. The improvement was of the magnitude that I got from the King Cobra. The sound gained a wonderful liquidity, smooth and detailed (I didn't think that was possible) the real diffrence was the way images were improved. Every sound now has such a definate place in space. I was skeptical and nervous when I first tried the King Cobra after spending that kind of money on a power cord. It was so obviously better than the Harmonic Tech Cord I replaced. I consider the Powersnakes in my sytem every bit as important as any of my major components.

Fbhifi - I'm currently evaluating EG Fat Boy's and Cobra Powersnakes on my tube monoblock amps. There are obvious differences. If your system tends to be overly rich or weighty without the EG Fat Boys, I'd lean toward the Powersnakes. However, the palpability, especially of vocalists, is better with the Fat Boys. The Cobras provide a slightly taller and wider soundstage, with excellent separation of instruments and timbral accuracy. My experience with ARC tube amps would suggest that the EG Fat Boys would be the best choice as long as you're using Powersnakes on the front end equipment. Just my $.02.
