Best ICE-powered amps ?

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.

Hobby, what have you replaced your JRDG 501 monos with?

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.
