Speaker driver question--is more better

I have posted a few threads here as I prepare to upgrade my audio system. I have noticed there seem to be two kinds of high end audio shops in the area. One type carries multi-driver (3 or greater) speakers + electorstatics (so think Martin Logan, B&W, Parasound, Aerial, etc.). The other type seem to carry almost exclusively two driver speakers. The think is, many of the speakers are at similar price points (4-8K). I had always assumed that more drivers (done well, of course) at a given price point were probably better, and to be honest I haven't taken the time to careful audition speakers at the the "two driver" store.

I recently read the following in an audiophile magazine: Full-range electrostatics, as well as some highly regarded two-way dynamic systems, solve the coherence problem at the expense of bottom-end extension and weight, and most limit dynamic output. The point was that lack of coherence of multi-driver system tends to muddle the sound stage and decrease the "realism" of the experience.

Thoughts?
