Founded in the 1950's by Saul Marantz, Marantz products arguably peaked in the 1970's, particularly with their line of 2200 series receivers. Today, the 2200 series receivers are immensely popular with audiophiles and audio collectors. Along with their power amplifiers, preamplifiers and tuners, Marantz is practically the definition of 1970's home entertainment. They won't tell you this on their website, but, unfortunately, by the time the early 1980's came along, most Marantz products were a mere shadow of their predecessors.
