No website that I am aware of, however there are lots of folks like you and I who still enjoy a/d/s components. I personally have made a large collection of their speakers as well as the Atelier series electronics.
Michael Kelly, the true mover and shaker at a/d/s back when, went on to found Aerial Acoustics. Mr. K is a very personable individual and most pleasant to talk to regarding the so called "golden years" of hifi.
Best,
