I ordered some cables from epiphany accoustics. I will report when I have them.
Don't know if the X1 needs a toxic cable , easy as it is.
Just received a Silver Poison for my He 500. Really wanted a copper cable but Frank had this one around
So.... After my first surprise , a totally different sound, I am totally addicted to the details , improved soundstage and instrument seperation with the Silver Poison. How does he do it? Silver , gold?
