There is no such thing as The SECOND Ultimate XLR!
You can get either The SECOND and that is, of course always arguably, one of the best neutral, spacious and "unelectrical" sounding interconnects on the market today. I'm using it between my Sony SACD-player (XA777ES) and pre-amp. This is a balanced cable so it will come in XLR as well as RCA.
The FIRST Ultimate is also a Carbon design but is coaxial so you can only use it unbalanced with a RCA connector.
