I am looking at a potential upgrade to the cable from the wall to my P20.
I am currently using an ASI Liveline Reference.
My local dealer is suggesting Audioquest Hurricane or Firebird, and Wireworld Platinum.
I mentioned Shunyata Sigma, based on the feedback on this forum. It is complicated for him to get that one, but he will try.
He will see what he can send me to try in my system.
Any feedback on these brands or suggestions of other ones welcome.
