Dear @lewm : As always there is nothing " new " about that cartridge. As a fact Micro Acoustics was who had more susccess about but they not named " ceramic ":.
""" The Micro-Acoustics cartridges had a different construction than Sonotone. The stylus arm was directly connected to the ceramic elements, an idea that was patented by Micro-Acoustics. The transducer elements were referred to as electrets, but were made of the same piezoelectric material, lead-zirconium titanate. The ceramic elements had resonance way above 20kHz to insure good response and separation to beyond 20kHz. The cartridges also had an internal microcircuit to convert the amplitude response of the piezo material to velocity equalization for use in a magnetic phono input on a preamplifier. ""
In the long MM/MC long thread was analizwed and I owned and own from the 2002e and other MA models and as I posted there and if I remember in other threads not only me but other gentlemans have a good opinion on the overall quality levels sound by Micro Acoustics cartridges. Comes as stand alone cartridges that you can mount in almost any tonearm well almost any tonearm because the MA are very ligth around 4gr and runs at 1gr. VTF and is a high compliance cartridge. Btw, in those old times MA developed and puts in the market a test/demostration LP recording that I own too and that time to time appears on ebay ( recomended ).
It runs directly in any MM phono stage and is not sensitive to load impedance/capacitance.
Here you can read something about and after that you can go to the 2002 model and you can take a look what a gentleman that owned sevral carrtridges like the Stanton 881S claimed and you know very well the 881 that’s " almost " the same as the 981 that you own:

Here on sale NOS and is the model I own for several years. Any one have to try/test/listen to these Micro-Acoustic cartridges including @fjn04 :
