Which Zu for you

I have Superfly and I have the Defheads (sealed top half of Definition).  I haven't heard Omen Def, but my Defheads are kinda like the Omen Def with a sealed cabinet and better cabinet build plus the Radian tweeter.  Let me tell you that Radian tweeter makes a difference, especially if you listen to a lot of digital.  I like my Defheads better, but the Superfly are no slouch.  I've used both tube and First Watt solid state amps.  If you want a big, rich deep sound, then probably go for Omen Def.  If you want a more intimate, focused sound, go for Superfly.  As much as I like my Superflys I have an itch to trade them in and go up the Zu line.

I use one of those tiny 3w Chinese tube amps from amazon with my Defheads and it sounds sublime.  How's that for a cheap integrated?

Zus are very revealing of amps.  I haven't used a vintage Marantz, but I have tried 70's vintage McIntosh solid state and Sansui.  They sounded a bit too warm and veiled for my taste.

Leotis, the twin driver models are 8 ohm.  Omen I believe is 12 ohm.

>Whoopycat does the defhead also give the emotional connection that the single driver provides?<

Yes and no... IMO the Defhead does dynamic peaks better and really puts you inside the music, whereas the Superfly has more of the "you are there, front row" intimacy.  As cobra213 has put in more eloquent terms in other threads, it depends on what you value more.  That said, I'm making the differences sound bigger than they are. 

BTW, my tube amp for the Defheads is similar to the Miniwatt that Robert used with his Supremes. 

Beautiful looking pair of honey walnut Superflys just went up on Zu's preloved site... that's a really good deal.
