I will try experimenting with toe-in and also possibly separating them a few inches. I was thinking of screwing down a couple of extensions on the top of my desk. I may end up fouling with my laptop though. The other thing I thought of doing was somehow dropping some plastic rods from the ceiling and securing them on there. That might be kind of kludgey though.

That's very interesting what you describe about soundstage and bass, Eric. I find that when I put them on the desk, they couple with the surface below and I get a bad resonance. Even now when they are mounted on 7 or 8 blank CD cases, I still get resonance. I've been thinking of putting some bubble wrap underneath them or maybe the same, beefy mounting feet that are on the amp.

As for the soundstage, when they are on your desk, do you have them angled up in some way? I find it difficult to understand how the soundstage can possibly be better when the sound field is below your ear level.
