Acoustic Zen, Reference 3A and ATC

I owned the de Capo BE's and now own AZ Adagios. They both do best what they do best. I would say the de Capo's are a bit more forward while the Adagios resolve better.

Either way you're going to listen to music for hours. The only reason why I moved to the Adagios ( a lateral move, really) is because we moved to a place where I could finally have a listening room that could fit floorstanders.

Another thing,
Ref 3A’s loudspeakers proclaim they are all phase coherent (basically due to a non existent crossover), so as are Acoustic Zens due to an implementation of Linkwitz - Riley type of crossover. I uderstood this well?
What about ATCs active loudspeakers with the active crossovers, can the active crossovers be equally as effective? I find this phase coherency thing important.

I was told by ATC people that for the active versions phase is adjusted

Many claim to be "phase correct" but all they really do is have all drivers in the same polarity.  This does not guarantee the speaker to be time and phase correct if fact they rarely are.  The only way to know is to look for the triangular step response in the Stereophile measurements.
