Larry, if the preamp question was directed to me, the answer is no. I've used a bunch of different "pre"s over the years, ranging from warm sounding tube units (Audible Illusions and Joule Electra) to more neutral sounding tube units (ARC) to classic SS sound (Benchmark). Depending on my mood (and the source material) I might favor any of the above on a given day. The AI is probably closest to the Cary sound and I liked that combo very much.
As always, YMMV.
