Man, I hate these threads. One cannot comment on which one is better unless you know what their system is comprised of. I have heard Zu speakers sound bad on one amp and then really good with another amp. Same goes for many other speakers or components in a system. I currently own three speakers, Vandy 5s, Meadowlarks Nighthawks and Alon V MKIIs. Each of them requires a different amp to make they sound their best. If you are buying anything without hearing it in your system, then you are a better person than I am. Even different amps from the same mfg sound different. I hope this was helpful.
Happy Listening.
