I agree with Phil. I have heard the Phil 3s, more than once. In my opinion, they (along with the Salk SoundScape 8, 10 & 12) are my absolute favorite speakers. All were designed by Dennis Murphy. If jdavis37 has a pair of Phil3s, I can't imagine what might be better.
I haven't heard the Crescendo II speakers. Do they really cost $18,000 per pair? In the past, I have heard another AZ floor-standing speaker, although I can't remember the model name. It was a 2-way 8" (?) coaxial speaker. I was not impressed by them. Their internet hype far out-shone what I heard in person – at an audio show in a hotel. As a result, I have severe doubts about that company, it's acoustic design expertise, and it's online promises & hype. I have no such doubt about Philharmonic Audio.
I find it noteworthy that many used Acoustic Zen speakers are for sale, but very few, if any, Phil3s are.
jdavis37 has listened to his Phi3s them for some time. I don't know how long that is, but in his own words, he has nothing negative to say about them. I suggest that many other speakers, regardless of price, will not be as satisfactory sounding to him.
