Budget is <$300 used. Cheers,
I am using the cheaper Siltech cord. A big improvement over stock but haven't tried those mentioned. Definitely better than older XLO that I have.
audio teckne about $250 new beats the crud out of anything I've tried on source components (betters the Harmonix $1000 cord that comes with my Reimyo transport) My dealer (palmetto audio-listed here on agon) carries JPS and it beats the stuffing out of it.
