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.
