I just returned the CT cables after a 12 day audition. I much preferred my HMS Gran Finale ICs and my DIY solid silver/teflon/cotton speaker cables.
I have been strongly considering Valhalla speaker cables, but the leaness that some describe has made me hesitant. I am currently burning in Pure Note Paragon speaker cables with power resistors. We shall see.
I also recently installed my 4th EG cord in my system - an Epiphany on my Berning ZH270. I still don't get how power cords can alter the sound so much, but this cord is staggeringly good.
