Based on the responses I will keep my eyes open for a 568.2mm.

Even though I am VERY happy with my Aerial Acoustics CC5 center channel speaker, I can't help but wonder if any of the Meridian speakers can even get close to the excellent performance the CC5 provides as a center channel speaker. The ability to not have to worry about separate amps is definitely a plus. Any experience here comparing Aerial centers to Meridian offerings?

Also, does the 568.2mm allow you to run the mains as active while you run the center to a separate amp and passive speakers, or, vice-versa?

If down the road I decide to go to a complete Meridian system this would allow me to buy the active speakers as funds allow. If this is possible I would most likely keep my surrounds passive as the wiring is already in place.
