Sonus Faber's Aïda
And then I got it. The speaker was named after Aïda, pronounced "eye-ee-duh," the well-know opera by Verdi. I guess the rep was not an opera fan.
With that out of the way, I was able to enjoy the Aïdas ($130,000/pair), driven by four Simaudio 880M monoblocks ($21,000 each). Paradoxically, they did not sound like giant speakerswhich I think of as a positive trait, and difficult to accomplish, especially when the speaker has multiple drivers, front and back, like the Aïda.
