Which speaker has the biggest sound stage?


I tried out a Magnepan 1.7 a couple months ago, and I am a bit shock by the sound stage of it. It just feel live music. Although the bass is a bit lacking, I really like the "be there" feeling.

So, my question is, does all planar speaker (electrostatic, ribbon ... ) have such big sound stage? And with different brands and models, which one has biggest sound stage?

Specifically for Magnepan, the 3.6 is about $1000 more than 1.6. What are the major differences? and is it worth the extra money?

I have box speakers that are out of the box with wall to wall and floor to ceiling staging... Caravelle's they are. Stand mounted in a room that measures 21.5 by 27 by 9. The way to achieve this performance is with resonance grounding a method of vibration control that does not squander the dynamics like that of bearings and sand and rubber bladders or carbon fiber or plastic or mdf or for that matter flat feet. This method is applied to all my components as well as to some of the room boundaries.

The 3.6 used is worth the price increase over the 1.6.
Be aware of how old the speakers are if you buy used.
Magnepans will have problems with the glue holding the Mylar and wires together. The reapir is not too difficult, but better to buy relatively new build speakers. Mande in last five years is better than older than that. And with the 1.6 and 3.6 longevity , many really old ones are out there.
