Lewm, the semi-auto SL-1700mk2 and its manual brother SL-1800mk2 and fully auto sister SL-1600mk2 are Adam’s rib from which the SL-1200mk2 was created. The main difference is that the SL-1200mk2 has virtually zero vibration isolation with its rubber base on relatively nice rubber feet. The SL-1200mk2 doesn’t have the combined TNRC substrate and spring suspension on rubber feet that its more sophisticated cousins have. These three different isolation systems work in combination to dispatch vibration very effectively. The SL-1200mk2 shares the same motor, quartz locked motor drive circuitry and tonearm, but lacks the enhanced cuing and pitch controls outside of the dustcover. The only reason that the SL-1200mk2 has an almost cult-like following is because of hoards of brainwashed rap-“DJ”s that think only a SL-1200mk(x) will work with their serato record scratching toys. For their purposes, the more sophisticated suspension interferes with their need to do what people who want to enjoy and preserve their record collection cringe at.
