What specific improvements are you looking for that you feel the Hegel H300
is lacking? 
Actually Hegel H300 is a very good amp , But It is like I want something new and provide me more musical, sweet or emotion to relax,. I think I already pass the word "critical listening" and move to "music lover" side for sure.
