I have been using a Diamondback since 2003. At that time, I had been using a Synergistic Master Coupler and ordered the Diamondback along with 3-4 other PCs up to around $350 each to perform a shootout. The Diamondback was the clear winner. The application for all was between a PS audio Ultimate Outlet and a Theta Pro Prime IIa DAC. I have only recently upgraded from the Diamondback to a Python CX, so it was in constant use in my system throughout various changes for over 7 years and I feel it is quite respectable for its retail price, especially for the prices they can be obtained at today.
Has anyone tried the Shunyata Diamondback PC?
Currently breaking-in 3 Shunyata power cords, I swapped them with PS Audio AC-3 cords. I have heard different opinions concerning this cord and would like some feedback from other users of this cord or what they have learned about it. The price of the cords was $125 each, about the most I can afford.
