I just checked out your amp, not familiar with it previously. It appears to use Wima and Muse electrolytic caps, those are good electrolytics, sill not up to good film caps. Wyred 4 Sound (Cullen circuits) does mods, check with them for possible upgrades in caps.
I also can't imagine that amp being responsible for the majority of your problem. ICE based amps are realatively warm, not biting. Could be your speakers, specifically those Eton metal dome tweeters.
