The Argent "Pursang" is a well-reviewed cable on the Net. I found it to be very open and detailed. I also like the performance in the bottom end. Contact info in on Audiogon.
I purchased my Supra Power Cords from Philefreak. These performed as well as my Elrod Signatures at a fraction of the cost. Contact Philefreak here on Audiogon for more information. The sound has been excellent. I still don't have them completely burned in, but if what I am hearing now is any indication of what is to come, I am in for a real treat.
Philefreak is also my source for the interconnects. I am sure he can help you there as well. I A B/ed them against some the most expensive and exotic cables available. These really work and at just a fraction of the cost of other cables that they put to shame.
