1972 saw the introduction of Mark Levinson's JC-1 preamplifier a concrete, functional symbol of Mark Levinson's approach to audio reproduction. With a signature blending of vision and science, it was the beginning of a series of groundbreaking audio components that reinforced America's reputation in high end audio design.
Indeed, the JC-1 taught even hardcore audiophiles tube components had no lock on aural truth. As the JC-1 evolved into the ML-1, it was joined by the ML-2 monophonic power amplifier. Mark Levinson then introduced the ML-3 power amplifier, a massive and ultra-stable dual-mono design that precisely controlled even the most difficult loudspeakers of its day.
By the mid's, despite innovations such as a fully modular preamplifier and extraordinary open-reel tape decks suitable for demanding studio recording sessions, Mark Levinson Audio Systems found itself in difficult financial straits. However, the Mark Levinson tradition of hand-crafted excellence was rescued by Madrigal Audio Laboratories, Mark Levinson's sister company distributor. Key personnel regrouped to continue design and production. The reorganization brought needed fiscal discipline and an expanded engineering staff.
