I had one of the original versions of the Z-cable Passion that I just sold about a year and a half ago. I personally knew Mark Hampton (the owner and builder of ZCable) and spent many hours at his house listening to his cables. The original Passion retailed for about $995. Each subsequent revision of Mark's cables went up in price. I would say this was probably in the $1500-$1800 category. I can tell you that the original Passion speaker cable that I had blew away the Transparent Audio Ultra cables that I was using at a fraction of the price. If someone has a good price on this it is a very good sounding cable with a lot of R&D into it. Mark started doing what he called "optimization" of his cables and it took these things to the next level. I honestly think you would have to spend twice as much to get half the cable.
