Hey Art, I can't help you with the difference between The 2, The 2 EX and The One, as I've never really compared them side by side against each other. I have used The 2 and The One interconnects in series, but not comparing one against the other. I can't imagine there is too much difference in tonal balance, though I'm sure that I will be told differently. ;) Welcome to the circus!!
I think your overall chance of finding a warm Tara Labs cable is about as good as finding a revealing Purist Audio, Jade Audio or Kubala Sosna cable though. I do think that knowing your tastes, you would find the K-S Emotion cables too warm for you.
I've owned the Jade Vermeil and the Hybrid, I never heard the Reference. Though I think the more gold that Jade uses, the warmer and slower the pace is. He uses gold plated silver in the Vermeil, and IMHO that is the quickest and liveliest Jade cable that I have heard. His Hybrid is all gold on the positive leg, and gold plated silver on the negative leg. It was richer, warmer and more colorful than the Vermeil. I believe that Jade is using all gold in the Reference, so it is probably even richer, warmer, and slower than the Hybrid. If that's any help.
