One of my favorites, though highly controversial, was the Aleph design by Nelson Pass. Large cube surrounded by black heat sinks. "Form follows function" to an extreme. One either loved them or hated them, but they were instantly recognizable as Pass amps.
They were replaced with the current thick silver faceplate with a large blue meter in the center. Again, instantly recognizable as a Pass design, but now instead of "form follows function", it seems to be more about design/asthetics and making a beautiful statement.
