@folkfreak, "over energized the top end". Now THAT is a good way to put it. So it was the super tweeter than was responsible for that sound, not the old Magico? I had heard Magicos before (I don't remember which model---it was at Brooks Berdan Ltd. a number of years back), but in a bigger room (the shop's main listening space, built to Cardas specs, I believe) and at a greater listening distance (and of course without your super tweeter).
I prefer a more "relaxed" high end than a hyper-detailed one, especially since much of my favorite music isn't in the best recorded sound quality. Of course, I don't want a too "forgiving" sound either. That's the balancing act we all are faced with; a musical reproduction system transparent enough to let the best recordings reach their full potential, yet not so ruthlessly revealing as to make lower sound quality recordings be unlistenable!
