I've had my Adagios running with an Ayre AX7e for sometime now and it is an excellent match. The reality is that Acoustic Zen's are pretty easy to drive and present a very linear load so they'll respond well to just about any amp you want to drive them with. The Ayre is incredibly clean and linear in response and its character works exceptionally well with the Adagio (which by the way, I personally have found to be one of the finest speakers money can buy! I'm a HUGE Acosutic Zen fan; you can see some of my reviews of their stuff here on 'Gon...)
I have thought about trying them with tubes. AZ has been showing their Crescendos with the big Tri monoblocks for the last year or so and they sound magnificent together. (Actually, I thought they had one of, if not THE best sound, at RMAF this year. Most of the rooms this year just sounded harsh and sterile for some reason, but the AZ/Tri room was the one place you could hear MUSIC). The BAT VK300 mentioned by Bizango is one I've strongly considered as well as the Genesis I60 or Music Reference amps. For now though, the Ayre sounds so good, I'm not sure if there's any real value in changing...
Happy Listening!
