A pair of Marantz 2 monoblock amplifiers, from the 1950's, which I purchased in the early 1990's and sold about a year later. Spectacular, lush, rich sound; exceptional build quality for their time; and a historically significant collectable. They were not quite powerful enough for the speakers I had at the time, though, and they were worth too much to be sitting on a shelf. Although they would be worth more than three times as much today :-(
