Moonguy, I am using the RCA type Ground Controls on my Cary. The Cary has both Balanced and RCA's out. The balanced outputs are sent to my Preamp leaving the RCA's open to be used with the Ground Controls (left and right channel).
I found the Ref RCA to be highly detailed with a somewhat narrower soundstage than the standard RCA. So, using one standard and one Ref RCA provided the wider soundstage with more detail. If I were to use only one RCA on the Cary I would use the standard.
I also prefer the stanadard spades on my speakers.
