Here we go again...Silver vs. Copper on P/C 's

I know that this topic has been discussed many times on Audiogon about the good and bad merits of each of these properties, but I would like to throw it out again to get some feedback. Looking at a very good P/C for my solid state amp.....Synergistic Research Absolute Reference Master Power Cord....it incorporates silver wiring. Some very reputable companies are using both silver and copper in their P/C's....some just copper wiring. I have ''heard'' some negative comments on the use of silver in P/C's ranging from ; too brite, too flat, no life, too harsh....So, looking for some comments on the Synergistic Research Absoloute Ref. cable and other's that might work on a system that has leaned towards being very ''rich'' sounding.
