You've run some pretty fancy MC's, but the _______ MM cartridge really impressed me

Sorry, here it's:

@lewm : This is the Sonotone that MA made reference. Btw, contrary to the MA ceramic/electret the Philips has a lean bass ( - 1.5db at 50hz to 500hz. ) that you correctly listened :

@lewm I am off the opinion it is not too many years before I hang up the gloves for the use of MC's. The design in my view will not be offering much more over an MM or others to be put to use, as my level of hearing will be deteriorating.

At present I have a range of MM's to bring back into regular use and the Ceramic Cart' has got about £50 tied up in it inclusive of the spare stylus, which will supply a very good investigation and experience for the outlays I have made. I have spent on quite a few occasions, more than £50 on unknown devices, just to see how they perform as a interface, and have kept them available for demo' and loan purposes even if not proving to be to my preference. Tube Rolling is just one experience, Platter Mats another, along with numerous Cables.  

The intention to do more to the Cart' and include a Boron Armature and Replacement Tip, will be the where the bulk of costs are to be associated. That is the cost to experience this Cart' as a bespoke design and to be produced as a build type that I would like experience. 

Raul, For what it’s worth I have an NOS Stanton 881S mk2, as well as an NOS Stanton 981LZS, and a used sample of 981LZS, as well. All thanks to you and your MM thread. Else I might never have appreciated the great now vintage MM and MI cartridges.

Back to the Philips.  It seems odd to first add a filter apparently built into the cartridge to make its voltage output vs frequency curve mimic that of a traditional magnetic cartridge and then connect its output to a conventional RIAA phono stage which re-corrects the frequency response.  Would it not be more pure to run the uncorrected output into a simple linear preamplifier?  (Yes, there is the shelf between 500Hz and 2kHz, built into the RIAA specification, but that by itself would be easier to compensate for in the preamplifier alone, or so it seems to me.)  I guess that built in filter (and reduction of voltage output) was deemed necessary back in the day to encourage sales to 'philes who already owned MM stages.
