I can say without question the Audio Refinement Complete is a standout amp for the $$$, having experienced it first hand. The one question you do have to ask yourself is what is my listening preference. You will have to run the Complete twice as hard as you ran your Rotel at volume, which will doubtlessly add an element of fatigue to your listening experience. So, no longer having that option should greatly effect your decision. I'd recommend the Primare 30.1 or the Classe CAP 2100 both great neutral integrateds that should help with your brightness problem, and you don't take that huge power hit. Might be a bit pricey new, but you can usually find deals here on audiogon. Happy Hunting...
