Hi- I have a 10 foot pair of Z-Cable Passion Mk 3 biwires that I actually just recently bought from another AC member. They were state of the art about 10 years ago. They are very musical with great bass and very nice detail. Also, easy to handle and not overly heavy. I wanted to compare them with my current Harmonic Technology Pro-9 Plus cables on my Vandersteens. In some ways they are more involving the the HTs, but with my whole system, they were a tad too dark, which the Vandies lean toward anyway.
The Z-Cable brand eventually became Clarity. They have very high quality solid copper spades on all ends, and they were just small enough to fit Vandy barrier strip connections. I’m hoping to get $400 for the pair. PM if you’d like photos or to discuss more. Thanks- Lincoln
