Today I have equalized both - FA4 and SD3 - down to what I consider neutral.
Firstly, I like the the Fischer Amps A LOT more with less sub-bass and less forward highs! And I do mean much better. I was grooving to Dave Brubeck like I seldom do. And since I "removed" the "frame" of which I talked earlier, which is some sort of subconscious misinterpretation in my head, I found the soundstage also to be very wide.
Equalizing the SD3 down to neutral takes a lot of depth away, but it doesn't quite appear as "flat" as the FA4 (sorry for bad wording, neither SD3 nor FA4 appear flat, just in comparison to stock tuning). There is still more of a 3D feel.
What I think where the big soundstage of StageDiver comes from, is that silence appears to be pitch black. I am not sure how to describe it, but it feels like there is some huge space waiting to be filled. Silence is perceptible. This might be a mind thing, but I wonder if somebody else feels the same.
Finally, the FA4 is a detail monster! But with the Carl Orff recording linked earlier, Chris Jones - Moonstruck and Maria Kordama playing Beethoven's piano sonata no. 14, the SD3 still has better resolution - no matter if I concentrate on the lows, mids or highs. It's not much and this should not be a reason to buy alone.
Both are great, take whichever sounding you prefer. I have given my personal opinion before, which should not matter to most of you, though.
