The almost total lack of participation in this thread proves yet again that ASR denizens really don't care for the sole purpose of stereo reproduction. Let them listen to their one speaker demos. Let them have their 'monitors' three feet apart on a desk, either side of a gaming screen in their mom's basement.
8-10ft apart in a decent room. Careful placement, excellently balanced signal chain at all volume levels, speakers that can maintain a rock solid image and, of course, recordings where some semblance of effort was put in to provide a sense of 3 dimensionality and placement.
