Zucable's Varial

Anyone out there using these ICs with their cdp? My new rig setup means I have to sell my Harmonix Golden Performance. Just too short no matter how I slice it. Zu does have a generous money back return policy, but I was just wondering if anyone out there has these babies in their system? Oops, just realized that I haven't checked the archives, but if any audiophools haven't contributed in the past, I'd certainly appreciate your feedback. thanks in advance. peace, warren :)
