I heard them, and I currently own a pair of Duettas that were upgraded to signature spec. Although the Analysis Audios do have the high end that ribbons are noted for, the midrange was a bit reticent, and the overall presentation was not up to the level of the Apogees.
Of course, the room could have played a major role in what I heard, but I have also heard Apogees in similar settings, and was far more impressed. There is an 'evenness' and liquidity to the sound of the Apogees that has not yet been duplicated successfully.
However, the high cost notwithstanding, I applaud any company for trying to bring back such a noteworthy speaker line, regardless of the name or country of origin.
And yes Dave, there were at least three models (Duettas, IIs, and Signatures, although I've heard of a Signature II, that I've never verified).
