When I talk classics, I mean amps such as Nelson's SA-1s, Krell KSA 50 or 100. Amps that transcend the normal. Again, I'm referring to the Aleph stereo model that was square in shape. I don't believe these particular stereo amps are as "collectable" as the SA-1s, or an S-500. Mind you, they have a following, as many of Nelson's products do, but those who like them perhaps may not have heard SA-1s. The Aleph monos are though, very very good. I have a dear reviewer friend who has them singing in his Wilson based system.
Just my thoughts,
Peter
