Having received a pair of Silkworm + IC's just a couple of weeks ago and giving them time to burn-in I have found these to be excellent sounding cables.
Tone is full, soundstage is large and focused and filled with detail. The cable performs very well at conveying, both musically and realistically, human voices and musical instruments.
My cable search is over. Very satisfying sound...
John, the owner of KCI, is also a great guy to work with.
