You may not have had in mind the tube-based amplifiers made by the original Saul Marantz company, but my nomination would be the Marantz 2 monoblock power amplifier.
Manufactured during the late 1950's and the very early 1960's, they are unquestionably among the best sounding vintage tube amplifiers ever made, and perhaps THE best. I had a pair about 20 years ago, which I still regret selling.
