Not sure about the spades.. mostly had Gold or Rhodium over the years but on wall receptacles I use the Furutech Cu, I have 3 Furutech NCF outlets in my power strip and rhodium NCF plugs on 3 of the 4 power cords I have..
But if I run the Furutech NCF at the wall feeding the whole system it's too much of a good thing the tonal balance gets ever so slightly white or grey sounding and not as natural as the copper feeding the whole system.
It's a definite balancing act and every system is different and all the platings have a different flavor. you don't know till you try.
