Power cord suggestions for Gryphon Antilleon Sig.

Please Gryphon Antilleon Signature users your suggestions for Power cords relating this amp.
Is it power-cord sensitive or not, please share your findings.
Siltech: Ruby Mountain.

Can't say if the amp is a/c cable sensitive as I've always been satisfied with this cable. I use Siltech throughout my system.

I've never been able to substantiate it, but I think Gryphon's own cables are, in fact, Siltech.
