Shure M91E (c. 1970–1971)
The Shure M91E is a phono cartridge from the early 1970s. It sat just below Shure's flagship V-15 Type II Improved. The surviving record is thin and mostly Shure's own advertising, which leaned hard on that comparison. The company's ads in HiFi/Stereo Review (August 1970, p.17) were blunt that the M91E could not track as well as the "incomparable" V-15, but could out-track everything else on the market.
Shure's advertising, including a placement in High Fidelity (July 1971, p.87), claimed the M91E would equal or exceed any other cartridge in trackability regardless of price, short of the V-15. It also said the M91E cost $15 to $50 less than its "lesser counterparts." The ads quoted period reviews too. Stereo Review (February 1969) called the listening quality excellent and said the M91E virtually matched the V-15 Type II in tracking the highest recorded levels found on modern recordings. High Fidelity (July 1969) described its sound as about as neutral and uncolored as any pickup they'd auditioned - clean, smooth, and well balanced across the range.
Beyond those advertising-era claims, little is documented about the M91E in available records. No full specifications, service literature, or introduction date have been located.
