ADC 10E Mk.IV (1972)
The ADC 10E is best known through its Mk.IV variant, introduced in 1972 as a high-end phono cartridge for the serious record collector. It tracked at an extraordinary 0.7 grams. The company claimed the whisper-light cantilever could pull detail from difficult discs that lesser cartridges would mistrack entirely. HiFI-Stereo (December 1971, p.44) tested a pre-production Mk.IV and measured its output at 3.6 mV at a reference 3.54 cm/sec recorded velocity. The review called that about average for a high-quality cartridge and found the tracking impressive. It also noted a slightly underdamped high-frequency resonance, which some listeners felt gave the cartridge an airy, open top end.
Later assessments come from collector experience, not period measurement. They describe the 10E Mk.IV as a cartridge with transparency and micro-detail retrieval that still impresses decades later. It doesn't shout its presence. It vanishes into the music. No original price, stylus type, frequency response, or channel separation figures survive in the printed record.
