I do have to agree with you Martin, I used all kinds of amps over the years, Marshal, Sims Watts, Carlsbro to Mesa Boogie, when I was looking for a new amp I heard the Fusion 550 head I was blown away by it's awesome sound, I bought it right there, I've never looked back, it reminded me of the Marshall's I used back in the 70's and I loved that sound, I don't go in for the kind of detail you have, but i know what I like, and this amp ticks all the box's.
