Excellent review of the AA's Ron.
When heard over here in Melb with Naim Statements that cost around 250K in Australia, I was completely taken up by their presentation. The dealer chap had three nmodels: the much smaller Omicron's, Epsilon and Omega's. I just enjoyed the little Omicron's and they looked cute all in white.
In reference to build quality, forget it! For the dollar price asking for Omicron's nearly 15K A$ definitely not worth it at all! Compared to the build quality of the newer Quads (2905/2912), the AA's are not even close, let alone the weight. I really don't know what it is but to me stats have always been my preference of that 99% of recorded music satisfaction. Martin Logan's yes, can sound a bit thin and so can similar stats but Quads are definitely not thin or skeletal sounding.
Perhaps the electronics were not upto the mark because I have heard my very own 2905's with the following: (cj ART Amps, Lamm ML series 2, Arc Ref150 and Ref75, and several iterations of cj 60 w/ch that are simply glorious with Quads, MC452 and more recently the Pass X series amps). To me horns are annoying, and the Trio's are extremely annoying. Heard them with Cary SET's and BAT amps as well as Gloden tube audio, back in 2005 and a few years ago around 2012/13.
For anyone to get that so called "best" sound would probably have to design and build their own speaker. Until someone else comes along and betters it still further, and the roller coaster begins again...
Overall, I think the ML Statement EII was a superb design, had all that wonderful stat speed, openness and strong bass as well. For a full range ribbon, there will never be another Apogee (the much beloved Diva's were finally sold off last year, too many repairs); from that I strongly feel the MG20.7 to be the all time best full range ribbon money can buy, and they are built far more rigid than AA's.
Having said that, now it is 11pm and I'm heading off to relax to some Quad stat & cj bliss. Good night to all.
Cheers, and all the best in your ultimate quest. With the right gear, careful listening and much patience, I am sure you'll find it Ron but remember don't be in a hurry, there is always something else round the corner...
