We should all be free to express our opinions
I think the point of the thread was to let people know that the review on the Persona's has validated what many people who have heard these speakers setup correctly already know. Paradigm has arrived in the uber speaker club and should be considered by anyone shopping for great speakers.
As per a time and phase aligned speaker being the only right speaker is poppy cock, There are many engineers that will not build first order crossovers due to the intrinsic demands that they make on the drivers employing overlapping frequencies, and the power handling demands placed on the drivers which then limit dynamics and causing greater distortion at higher spls, due to the greater bandwidth necessitated by these designs causing increased heating of the voice coils which adds distortion, add lobbing effects lat the pass band, and these kinds of designs also have serious trade offs to offset the advantages in just preserving time coherency.
However, not all listeners are sensitive to time related effects and a rooms interaction with a set of speakers in terms of setting overall diffraction and reverberation times, usually create more adverse time related distortions than if a speaker better tracks a microphone because the wave launch of the drivers is all in phase, vs not being in phase in the first place.
In the annuls of audio you have had great speakers with all different types of crossover designs:
The legendary JSE infinite slope, the famous Spica TC 50 which combined a first order and fourth order crossover slope, The Infinity IRS, The Infinity RS 1B whiich employed I think third order and second order slopes. the Quad ESL, and ESL 63, The Wilson Watt Puppy, and many, many more.
