Interesting revival of an old thread! As a precurse to your quest and looking at your shortlists, here are some subjective comments.
I would prefer the Vitus to the Gryphon 120, but I might prefer the 300 to the Vitus. The Vitus is very controlled, extended and authoritative, I find the big Gryphon a tad more relaxed in the high register, but very capable as well.
As I remember it, the big ASR (the 3 box model) sounded a bit tinny by comparison.
If you like the Gryphon sound, you might also consider a CH Precision integrated.
Good luck!
