Shure M91ED

The Shure M91ED is an MM design whose 5 mV output feeds any standard MM phono input without extra gain. Its replaceable N91ED stylus carries an elliptical profile that traces groove modulation with good detail. The rated tracking force runs from 0.75 to 1.5 g, keeping pressure on records light. Phono Culture lists three compatible replacement styli for this cartridge.

Additional Info

The Shure M91ED is a warm, forgiving MM with a natural, relaxed vocal presence that favors ease of listening over forensic detail. Bass carries decent body without turning heavy, and the elliptical tip keeps imaging reasonably focused while smoothing sibilance. A tubular aluminum-alloy cantilever adds to the mellow, non-fatiguing character that flatters brighter systems. The stylus is replaceable, so upkeep stays trivial.

Картридж Shure M91ED (ММ, 5 г) с высокой динамической податливостью 30×10⁻⁶ см/дин требует лёгкого тонарма — низкая эффективная масса даёт резонанс около 7,9 Гц при 8 г, что приемлемо; тонармы от 12 г и выше смещают резонанс в проблемную зону. Фонокорректор: нагрузка 47 кОм || 400–500 пФ, усиление 35–38 дБ. Кантилевер алюминиевый трубчатый — заточка иглы стандартная, без особых требований к прижимной силе сверх рекомендуемой производителем.
