A true classic, the very best SME ever made and one of the very finest pivot arms on the planet IMHO.
Totally agree that SME went a wrong way after it.
I bought one in 1987 to fit my very compliant Shure V15V-MR. I couldnĀ“t find better arm on the market.
Especially in the mid range the SME III shines, very nuanced, smooth and musical. Also the highs such as cymbals etc are extremely enjoyable. Huge soundstage.
The S-shaped wand with internally teak damped 4.5 gram titanium-nitride wand fits the fuzziest carts. Simply adding mass a few grams (two options) on the headshell it fits also less compliant carts. Also you can adjust counterweight mass to fit different compliances. Knife edge vertical bearing and mechanical anti skate adjustment are simple and work just fine.
Fluid damping also reduces resonances. The design is not too complicated so it works nicely.
British engineering of the highest quality from the golden era, a State of the Art product indeed.
