Hi Carl You have been busy I must say. BTW try the YBA diamond pwr cord when time permits. Currently have one on my wadia 12 dac. Keep tweeking
MY Sidewinder AC cord progress:
This is a demo from the Cable Company. They burned it in for 250 hours, and sent it to me. I plugged my Krell amp into it, and directly into the wall outlet. After a 24 hour settling time, I listened. Very bright, dynamically laid back, zero bass in the bottom two octaves, wide and shallow soundstage (that's a function of the brightness, IMHO). So far, not the best AC cord I've tried with my amp. MORE LATER....
