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 ?

By all means do. I'm curious on your opinion on Kharma amp. I have heard it during CES, but never had a chance to try it at home.

BTW - how does the Ayre compare to Pass ?
I like the Ayre more. Pass is good too but the Ayre gives me a more easy listening experience. I was told to try Edge Class D amps as well but I´m not that convinced as I´ve once had the chance to listen to a shoot out between Edge NL 12.1 and Boulder 1060 and the Boulder was by quite a big margin the winner to all auditors and I find the V-1xe quite close to the 1060.
Edge digital amps are also ICEpower based, so they will sound very much like JRDG amps.
Elberoth2: you might be right and I must honestly say that I did to much equippment swaps and shoot outs this year and that I´m worn out doing more listening sessions.. I finally always return to Ayre gear (as I can´t afford the very expensive Boulder amps I like most - followed by Ayre gear).. And I´m very close to leave everything as it is and just add the forthcoming Boulder 865 into my system and compare it to my current pre-power combo and either sell him or keep him.
I have replaced my JRDG 501 because I found them too boring in the long run. Very analytical and controlled, better than most other ICE's, but ICE amps are not musical enough for my taste.
