Acoustic Zen Adagio, How Good Are They?

No. The mid/bass drivers are custom made (not in China) and the tweeter is custom assembled by hand in CA by Robert Lee himself. Every speaker is assembled and tested in CA. Robert Lee actually listens to each individual pair in a system before they ship.
How many speaker companies will actually audition each pair or <$5k speaker, by the owner even, before headed to their new home!! These are not an assembly line product.

Yagbol2, I didn't think it would come across like that. If it was offensive to you, for that I appologize.

My ICs and speaker cables are all Acoustic Zen and Robert Lee is one of the best cable designers today and I have not heard better cables than AZ in the price range. When someone wants a cable recommendation, AZ is the first brand of cables I recommend.

What I was trying to say, and I probably had to be more clear about it, is that if the Adagio speakers are indeed made in China, it should not be a hidden fact, don't you agree? I have no problems with where equipment is made, as long as it is high quality and sounds good. I just think if it says made in USA it can not be made in China or anywhere else for that matter.
And to let you know, I just listened to Cayin, VAS and Aurum Cantus Volla speakers and thought all of these components sounded awesome. I especially liked the Cayin integrated. If I am not mistaking, all of these are made in China.
I have no problems with where equipment is made, as long as it is high quality and sounds good.

I believe the cabinents are sourced from China. The reason I say this is because my dealer and I were talking about the "new" Adagio model and he called AZ to inquire when they would be ready. AZ informed him that they had a container in port waiting to clear customs. By the way, the new models have a slanted baffle to reorient the mid-range drivers (ala JMLAB Mini Utopia) to "focus" the sound toward the tweeter. Additionally, they now produce a monitor version of the Adagio with the same driver layout, about half as high with the transmission line exiting the rear of the speaker. New colors includiing a metallic/graphite.

As far as their provenence, I would say that they are designed and assembled in the US with parts sourced from overseas. Cool! Keep up the great work Robert Lee!

how do these speakers compare with the Proac D25 which is similar in price range ?

A question for you Adagio users, any thoughts on supports? I have a carpet on a suspended wooden floor and have the version of spikes with a blunt rounded end, though of course I can change to true spikes. Has anyone experimented with supports for the speaker, not too obtrusive if possible? Additionally, any thoughts on positioning. Ihave mine about 7ft apart straight down the room with no intowing and about 15 inches from bookshelves behind. I think these speakers are so good, they deserve a bit of effort to get the very best out of them.
