Micro Acoustic Cartridges


Does anyone remember the operation principle of these cartridges?

Tubegb, thanks for the link. I have never heard the shimmering symbols on Paul Simmon's " Slip Slide'n Away" reproduced better than a Mico Acoustic cartridge did it. Also, the rain in "Fresh Air One" was extraordinarily palpable.
Yep.  Loved the 2002e back in 1978.  It was pretty good in my basic system powering Large Advents.  Piezoelectric, if I recall.
I owned one of the 2002 series (when my ears were younger) and I remember fantastic amounts of "micro" detail.

Back in the day I used the following models: QDC-1E, 2002E and 530MP. All were fitted to a very low mass tonearm with knife-edge bearings (Infinity Black Widow). All shared similar basic characteristics: low physical mass, lightning fast transient response and excellent tacking at 1 gram tracking force. (The later very much counter to what we’ve learned since.)


Here’s an excellent summary on the company history and the cartridge(s) construction/design principles: http://www.roger-russell.com/sonopg/micropg.htm
