Rickmac - The Cello Amati speaker was closely based on the AR LST speaker. Mark Levinson designed the crossover. It was considered high end with a suitably high price tag.
My bad, although I began in audio so long ago that my first speaker [mono] was an AR 2, now I think of AR as being Audio Research and not Acoustic Research.
AR=Acoustic Research ARC-Audio Research Corporation
At least, that's how they used to do it back in the 80's and 90's in the Sunday New York Times classified. That was before the internet and Audiogon and Audioreview.
Also, it the intervening years the status of Acoustic Research has descended to big box store marketing product.
Maybe this equipment was so obscure that no one remembers it. I remember ads in Audio inside the covers announcing this line. There were some pretty sexy shots of the faceplates in the ad. There was to be a preamp with tone control setup simular to and designed by Cello.And no, it wasn't their April issue! I think the relationship between Cello and AR is simular to that of Pass and Adcom. It is possible the equipment was prototyped but never sold. I heard a pair of ESS Transars in the early 80's which I'm not sure were ever marketed.
