Acoustic Zen Crescendos- Any Owners Out There?

I am most definitely not experiencing one note bass. In fact, the bass of the Crescendos seems more articulate than my previous speakers, Monitor Audio GS 60's.
I am hesitant to post any type of full review just yet for several reasons. The speakers are too new, an I'm no Harry Pearson.
Here are a few comparisons with some speakers I've demo'd in my house recently:
ZU Audio Definitions- the treble is much better integrated in the Crescendos. The Definitions had certain high frequencies that would just leap out at you. They also did not image as well as the Crescendos. The guys at Zu suspected an amp mismatch, and I have no reason to dispute this. Bass was not as articulate as either the GS 60's or the Crescendos.
Reference 3a Grand Veena- This speaker sounded very good overall, but would harden up at any volume over 95db. I would expect this in a small stand mounted speaker, but this was a 50" floorstander. The Crescendo does not sound quite as open, but does high volume much better. Bass in the Crescendo is also fuller, and to my ears just as articulate.
Monitor Audio GS60- This is a great speaker. I have spent 3 years looking to better them. What I don't care for in them is a lean tonal balance. What I love about them is their very open sound and a tremendous ability to play loudly with no strain.
Take these comparisons for what they are- I don't have a perfect room, nor perfect ears. I am not necessarily going for absolute neutrality, but a sound that is pleasing to me.
Lastly, these thoughts are based on 3 day old speakers, hardly broken in. The amplifier used is the LSA Signature integrated.
I will post further thoughts as they break in.

James, curious what kind of music you listen to?

James, I've demoed those speakers several times, including at the aforementioned meet.

I agree that their bass is anything but "one note". I found their low end well defined and very extended.

But when you audition them by standing in the back or corner of the room, with people standing all over the place, usually chatting away, I couldn't think of a worse way to audition anything. There was also a mini DAC shootout that took place that day and both DAC's were a little loose in the bottom end.

Jeff,
My tastes run the gamut- in some semblance of 'airtime':

Rock / pop 40%
Blues 30%
50's / 60's Jazz 20%
World/Ethnic/Anything goes 10%

What I EMPHATICALLY don't listen to are so-called audiophile recordings.

Just want to add I had a similar issue with Zu Definitions on bright top end as a result of a lean midrange---turned out it was a very poor match with my BAT integrated. I switched to a McIntosh and things fell right into place.

It was very similar to JA's view of the Essence in Stereophile---he switched to a tube amp for the same reasons. With no crossover, I've never heard a speaker so amplifier dependent---it's like the amp goes straight to the coils of these speakers (same could be said probably for Audio Note, Avantgarde, and other HE speakers).

Zu Definitions should be paired with warm SS (ala McIntosh) or a tube amp imo. I think AZs should be paired with tube amps as well from my limited experience with the Adagios.
