Physics laws are what they are. I stated that 2M Red causes more record wear than 2M Blue - in the treble, despite both having the same elliptical srtylus tip profile.
F = m x a or Force equals mass multiplied by the acceleration. Mass of a bushed or shank mounted stylus IS bigger than nude mounted one - by at least 50 % or so.The stylus tip profile is for both the same - elliptical as per Ortofon specs. It does cause no difference in the low(er) frequency range.
Trouble in analog, and what you really are paying for in cartridge/stylus, are high frequencies. Do you know what are accelerations in the record groove at the high frequencies , say above 5 kHz and usually peaking at around 10 kHz ? No ? Try 2000 G, or two thousand times the acceleration of earth's gravity !!!
That 2000 G is admittedly extreme, corresponding to approx 100 cm/sec velocity in the groove, achieved by state of the art recordings. But even if you cut that in half for normal recordings, a nude mounted lighter stylus with the same profile will track highs better than chubbier shank mounted stylus of the same profile. Do not have no 2Ms handy to make photos of real styli like I did for Shure, but the difference, although less severe, is still in similar ballpark.
It is glaringly obvious to the naked eye when observing the performance of carts when tracking test signals on the oscilloscope - the lower mass version, if not defective for any reason, will ALWAYS win.
There are many ways to graphically present this - Shure had Trackability Curve, Technics Mechanical Impedance, etc, etc - yet all are basically telling you the same thing. You have given maximum Force F ( usually that VTF of say 1 or 2 grams or 10 or 20 mN to be exact ) - and if the acceleration in the groove exceeds the value under which your stylus with effective mass of so and so much mass can still maintain contact with the groove, mistracking ( gross distortion and guaranteed permanent demage to vinyl ) will occur. Physics shows no mercy for our wallets - period. Older Shure brochures had SEM ( Scanning Electron Microscope ) images of portions of the groove with hot high frequency signals, usually made first after playing with some top Shure (showing no demage) and then after a single play with a lesser trackability competitor's cartridge - no pretty sight, let alone listen. Definitely have to get my scanner up and running !
Above is a simplification of the real state of affairs. It assumes vinyl groove rigidity/elasticity to be infinite - which of course is not the case in real life. The objective is to place the resonant frequency at which effective mass of the stylus resonates against yielding of the vinyl groove as high as possible - which of course again favours lower mass and higher contact areas ( better tip profiles). You basically can not retrieve frequencies much above this inherent mechanical resonance from the vinyl groove - and only by lowering of the effective tip mass to unheard of 0.055 mg was possible to place this resonance above 70 kHz and still having reasonable flat response to 120 kHz. This measure gets you ruler flat response anywhere in the audio band so to speak for free ( and, believe me, they did ascertain that electrical part of the cartridge was capable of transducing that formidable mechanical response intact into an electrical signal ).
Since you do own quite a formidable cartridge collection - get an inexpensive LP, preferably new, of some music that you could not care less about, and find a track with pretty hot recorded treble (cymbals, trumpet, percussion, sibilants, etc ). Play it with LP S MR. Play it say 5 times with 2M Red. Re listen with LP S MR. Play it again for say 20 times with 2M Red. Re-listen with LP S MR. If that survives kinda still acceptable (due to the MR stylus which does find virgin portions of the grrove and still sounds acceptable ), re listen with DL-304, which has something approaching hyper elliptical stylus tip profile IIRC - and can not avoid demaged portion of the groove. Any elliptical or conical would be much worse still.
Now imagine you did that to your ENTIRE VINYL COLLECTION - and ask yourself whether it was worth saving those $ 100 ( difference red blue ) as opposed to $ ?000 worth of your vinyl.
Once upon a time, many full moons ago, when test records still were readily available ( at cost ), every test record at Benz's carried an Bruel & Kjaer printout - recorded with a reference cartridge. First was new - over that taped another after so and so many measurements of every cart on the production line. Believe me, the last one visible on the top is nothing you would want to show the digital camp - and that using top quality nude mounted low effective mass styli of about 0.2 mg effective mass with VdH/ Fritz Gyger or Micro Ridge profile. Then check specs for 2M Red. And repeat - holly horror - with OM3e. Still elliptical.
You will notice there is NO effective mass specification in current Ortofon specification sheets - despite each and every other aspect defining cartridge performance is properly specified.
No prizes for guessing why this is so.
