Bondmap,
I used to have a pair of Vandy 2C's (original model) many years ago. I cherished them for their ability to throw a large soundstage, but the Ohm's trounce them in that department with the right source material.
I agree with Mapman that much of the soundstage presentation takes place behind the speakers, but not entirely. On "The Goodbye Look" from Donald Fagen's "The Nightfly," the percussion, especially the marimba parts, reach out into the room toward you. On "Let's Face The Music And Dance" from Diana Krall's "When I Look In Your Eyes," the piano part also reaches right out into the room. And on pretty much all of the Steely Dan album "Two Against Nature," there are keyboard parts swimming right in front of your nose like nobody's business! :-)
I also remember loving Sade's "Is It A Crime" track from one of her first LP's on the Vandy's, because of how wide the soundstage extended, and the Ohms do at least as well on that track.
What I will say is that the Ohms seem to me to be more forgiving in terms of placement than my old 2C's. I remember lots of futzing around with the Vandy's in terms of distance from any walls, vertical tilt, and so forth. With the Ohm's it's been simpler for me.
I also wouldn't underestimate the convenience of fine tuning speaker placement with a speaker that doesn't require spikes! :-)
