SME is a brand name of an English company that produces high end tonearms and turntables, whose name has become synonymous with the industry standard detachable headshell mount.
SME was formed in 1946 under the title The Scale Model Equipment Company Limited to manufacture scale models and detail parts for the model engineering trade. During the 1950s the company moved away from model making to precision engineering, principally parts for aircraft instruments and business machines.
In 1959 Alastair Robertson-Aikman, the Company's founder, required a pick-up arm for his own use and an experimental model was built. It received such an enthusiastic reception from friends in the sound industry that it was decided to produce it commercially and the first SME precision pick-up arm appeared in September 1959. Production was 25 units per week composed entirely of individually machined components. At this time a new factory situated in Mill Road, Steyning was opened and the Company's name was changed to SME Limited, a less committal title to suit its new activities. new company MD july 2016
The company is notable for its 3009 and 3012 (9" and 12" respectively) tone arms which were widely adopted for audiophile and broadcast use during the 1960s and 1970s, at the higher end of the market. These arms featured a polished stainless steel main tube with a lightweight headshell, knife edge horizontal bearings, and an anti skating bias provided by a weight that hung by a nylon filament. Versions were produced with both fixed and interchangeable headshells; the SME headshell mount became the de facto industry standard, and is still widely used today on consumer and especially DJ decks. Audiophile arms today tend to not use the SME mount, but this is not due to other standards replacing the SME but because audiophile arms now tend to not have interchangeable headshells at all in an effort to reduce mass and improve rigidity, though at slight expense of user flexibility.
Some cartridges were produced that mounted directly into the SME headshell mount of the arm (rather than into a headshell), notably from Ortofon.
The Series III was introduced in the late 1970s incorporating changes from the Series II models (which continued in production) covering both styling and its exceptionally thin and lightweight main tube, the entire arm being interchangeable rather than just the headshell. Although technically advanced, the Series III never achieved the market dominance of the Series II.
