There are some sites that do give very detailed specs as to speaker postitioning and distance...even has a mathmatical equation. I was addicted to achieving that 'perfect equation' but then found all room interactions are different and no equations can account for them all. Plus the influence gear has on sound is such a huge variable with no real explanation as to why amp a gives better soundstage over amp b. It sounds as though you have found what i found...ya just gotta play and see what happens.
As to what should sound stage sound like? Well I think you heard it when you were cleaning. At least that's what I think soundstage should sound like. I was also amazed with the '3-D' sound when watching a dvd through my 2-channel setup. I don't miss HT at all. Try rotating the speakers a little (toe in) to see if you can expand the sweet spot a little.
I also think you found the other secret...a little liquor (or is it just being relaxed?) that makes it all a little better.
