Optimal Placement for Magnepan 3.6?

Distance from rear wall and side walls….distance between speakers (imaging)….distance from speakers to listening position?

Concerns: Unwanted glare from ribbon tweeter. Room dimension constraints (how small is too small…speakers need room to breathe).

Also: concerning bass extension…in a small room are the 3.6’s adequate without a sub? How well does the 3.6 integrate with a sub?

Background: I want more resolution…I seek a more resolving speaker. I truly enjoy my Krell Res 2s because they are incredibly dynamic and cohesive and they maintain control at extremely high volume levels. They work great on large orchestral movements, rock and any other music with great dynamic contrasts. I do however yearn for the superior resolution of planner speakers when I listen to acoustic music and vocals. I admire the strengths of the Krells, but since I spend more time listening to acoustic jazz, acoustic guitar, vocals and string arrangements, I feel the need to make a change.

Right now, I just need basic information regarding optimal setup requirements. At this point, my actual room measurements are of little consequence.

Note: This is a Magnepan 3.6 thread. At this time, I am not interested in hearing about other speakers (unless they can be had at the same price as the 3.6s and offer the same - or better, attributes).
Thanks
