I've decided on the ZIIs. MIT still recommends them with the Z Center for digital gear. I heard several more expensive cables (not the ZIIIs) and I did not like the upper mid brightness. The ZIIs were more detailed and space defining than the original cords, but retained a very musical richness and smoothness throughout. My gear: Wadia 270se and 27, ARC 150 amps and Thiel 5i speakers.
