Rwwear has it right. Audioquest could be the culprit of the confusion (no offense to AQ--I do like their cables), but they did a long line of "triple balanced, RCA or XLR connections" they also had a previous line of "double balanced" Then they changed to calling them "X3" version rather than triple balanced, probably due to this confusion. The balanced aspect referred to the wire. But as stated to get true balanced functionality you need the XLR connection.
What does this mean?
"Interconnect 1.5 meter Balanced RCA" - I thought only XLR or phone connections could be balanced? What am I missing here? Can someone explain?
