Yes, that is the color of the speaker cable and the 3x4 does mean version 3 bi-wire from what I remember. The original Passion I purchased from Mark was amazing. Mark spent a lot of time working on his cables to perfect them. Unfortunately, he had two strokes and that got him out of the cable business. He then sold the company to a local couple in Wichita,KS and they renamed it Clarity Cable. I would say that it is on a completely different level than the cables you mentioned. As I mentioned I was using Transparent Audio Ultra cabling in my system both interconnects and speaker cables (bi-wire). When Mark came over to my home and we started putting the cables in my system I was amazed at what I was missing with the Transparent cables. It was as dramatic as changing each component of my system. Mark's cables were an amazing bargain. I sold my Passion speaker cables to a very good friend of mine about a year and a half ago for $400. The problem is that people have never really heard of them and since Z-cable is no longer a company others may not know the value. I guess for me I would not pay any more than $500 for them, but they are certainly worth the money. As well, the ICs I was using there Live V2 which were very good. All of these cables were cryoed too. Mark started to cryo cables back in 98-99 or so.
