My experience with Vandys is they are among the best in soundstage, imaging, depth, etc. I also think the Arcam is probably greatly limiting what you're getting out of your speakers. That said, when the wife's not around I'd suggest pulling the speakers 4, 5, and even 6 feet into the room and see what happens to your depth of stage (and of course use recordings that contain that type of material), just for your own reference if nothing else. I bet you will hear much more of what you're looking for specifically in terms of depth despite the Arcam handicap. Others with more experience with Vandys may have more informed opinions on this, but 3 feet from the back wall would seem to at least somewhat limit the depth of stage you're currently perceiving. And getting a good stereo pre should greatly improve imaging, depth, etc. even further. Best of luck.
