Power Snake Mamba vs. Synergistic Master

I never tried the standard Mamba, it was dicontinued too quickly (like after 2 months, or something). I liked the Reference Master Coupler better than the Black Mamba with either my Rogue or Krell amps. I liked the Black Mamba better than the standard Master Coupler, however. I didn't like any of them on my CD player. Search the threads for my extensive comparison of all of these, and more. It was called "My Sidewinder progress", began in May 2000...Now, the SR Reference seems to be beating the FIM Gold cord on my Rogue amp, ever since I got a PS300 for the CD player.
