Ortofon MC-A90. From the un-serialized second production run. Mounted on my second arm and rarely used. Less than 300 hours (very conservative estimate.) My Lyra is in need of replacement so this cartridge is offered for your consideration. Incredible detail and unfailingly neutral. It tells the truth.

Comes with original box but not the outer slip cover. No accessories- if I do locate the safe place they have been stored I will forward to the buyer. 8/10 as it has been mounted and played (only on cleaned records- ultrasonic.)

Michael Fremer sez ; "the MC A90 maintained the Windfeld’s tonal neutrality while adding unsurpassed rhythmic swagger, dynamic exuberance, transparency, and three-dimensionality unmatched by any other cartridge I’ve heard. Low level dynamic gradations were revelatory, while the big ones were unrestrained and positively energetic. The MC A90’s attack was faster, cleaner, more precisely defined than that of any cartridge I’ve heard, and with no hint of brightness or unnatural edge. Its decay was equally clean and effervescent, fading quickly to inky-black backdrops."
