@wgb113 Thanks, I look forward to your sonic impressions. I wasn't a believer in differences myself between silver and copper for your reason exactly until I tried a few that is.
I have 1 silver power cord and 1 hybrid silver/copper cord, amp and pre-amp and my SACDP uses its stock cord still. There is old whatever wire, looks like copper to me, they used in the early 1960's in the wall. The peculiar thing is when I change the cords around my sound goes into the dumpster. To exclude a one-off occurrence I tried it on several different occasions with the same results. Any insight to why?
