Optical pick-ups were a dream in the 1960s and 1970s, but they were hamstrung by the light technology of the era. Weight, heat, power source - all mitigated against it. DS Audio, however, has the benefit of returning to the concept in the age of the LED, and its parent company is a global giant making optical sensors. Your £20k for the DS Audio Master 1 package, then, gets you cutting-edge design and manufacture rather than something a boffin cooked up in a garage. It also pays for the latest power supply-cum-phono stage, the cartridge not delivering a signal suitable for a conventional MM or MC phono input.
