Guys lets just value our differences here, at the end of the day, we are all hobbyist in this field right? Sandu is a very good reviewer, I like him a lot and sometime I find myself disagree with him at some points, it is just the matter of my taste and my preferences toward what is best for me. One thing I would say though if you are a fan of huge soundstage and holographic, A90 is very very good but it is not quite up there with the big boy yet, other than that, what can I say, a very impressive amp for its price and you cannot go wrong or regret your decision at the price point.
