The original Shure V-15 phono cartridge debuted in 1964 as a "statement" design. The engineering team was headed by Jim Kogen, who later became a Vice President of Engineering, and after that the CEO. The V-15 Type II arrived six years later and it was the first computer-designed cartridge. The Type III was the best selling model in the series, it came along three years later, long before the CD changed the course of audio history.
Shure was huge in the mainstream market, but by the late 1970s and through the 1980s most analog-loving audiophiles had graduated to moving-coil cartridges (the V-15 was a moving-magnet design). I preferred the sound of moving coil cartridges, but conceded the V-15's tracking abilities were well ahead of most of the expensive Japanese moving coil designs of the time.
