They're a bad fit because the Zu FRD sounds best with an amp with a relatively low damping factor. That's what it's designed for. Bass will be overly damped (dry, thin) with any kind of digital or switching amp.
Zu Omen Defs and Ice Amps?
Anyone have the opportunity to audition a pair of Zu Omen Definitions and a Class D or Ice Amp? The Zu's obviously don't need a lot of power so I'm thinking one of these newer digital amps might be a good fit. If so, please share the make/model of amp and your impressions. So far, I'm considering the King Rex, Trends, Dayton, and Topping amps but I'm sure I've left a few out that might be contenders. Thanks in advance.
