For me, I'm pretty happy if things are just detached from the speakers and I'm not very aware of the drivers. Speakers like Wilsons & Kharmas do some magic tricks with spatial cues, but often with the cost of over-analytical tonality.
Sound stage, front, middle, or behind your speaker
I've heard all three, and it seemed to have nothing to do with the quality of the speaker. I have dipole speakers and the sound stage is 7 feet behind the speakers. I suppose there are a number of variables that will determine in front or behind; the question is whether or not this is determined by the position of the speaker or the speaker it self?
