I'm in agreement with Ton1313. You can't go wrong with the Zu Wax. I am not familiar with Z cable stuff so I'm not able to comment. I have had several other top quality speaker cables and the Wax is significantly better. There is an auction for an 8 ft. bi-wired pair going on now on this site, and they also have one for auction on Ebay.If you don't like it after a while, send them back for a refund. Check out the customer reviews on Zu's website, www.zucable.com. Just in the last month, the Wax have gained so much popularity that winning bids have almost doubled. It won't be long before Zu stops the auctions and starts selling at retail. Good luck and happy listening.If you do go with any of the Zu products, especially the new B3 technology lines, give them adequate burn in time. My Wax took almost 2 weeks of continous burn-in before they began to really open up. The first week they go through a weird metamorphosis that is very frustrating, especially into the fourth day when they go through a tipped-up edgy sound, but that goes away. What I'm saying is to be very patient with these babies before you pass any judgement.If you don't like them after a serious audition after break-in period, then I would recommend you look for a cable that has certain euphonic colorations that meet your needs.
