Best ICE-powered amps ?


I´m thinking of building a nice second system around ICE powered amps but haven´t got a clue (and currently not the time) to compare them.

The ones I know and heard good things of are:
- JRDG 501
- Bel Canto e.One Ref. 1000s
- NuForce Ref. 9 SE
- Red Dragon

Which one is the best ? Are there any ICE power experts on agon ?

Has anyone tried different combinations of upstream components with these amps, or just dropping them into existing systems that had been balanced around different technologies?

I think I'm going to try the evo 1000's with a few different tube front ends.
Hobby, I also like the Theta Citadels a great deal. Do you happen to know what is the technology behind them? The Theta web site is rather vague, stating only that they are based on some enhanced versions of the Dreadnaught modules. They run very cool, almost as if they were digital amps. . . but are they?
