Curious Why Benz Micro Slid Into Obscurity

Actually, in the “good old days”, cartridge bodies of all types were typically made of plastic. Inexpensive and both strong and stiff plastic. Koetsu was fairly unique in offering wood bodies with exotic Japanese lacquer finishes. Metal bodies heralded the “modern era”. Ortofon was one of the first to offer titanium, although someone else may point out otherwise. Anyway with metal bodies and good marketing higher prices than ever before could be rationalized.

47,000/16 = ~3000 ohms.  Difference between 3000 and 1000 ohms should not be audible BUT I don't know where you are going to find a SUT with a 1:4 turns ratio, unless you have it custom built, the cost of which is in my opinion exorbitant if you are specifically trying to make a Glider work properly.  But that reflects my medium opinion of the Glider.  Actually, why do you need any SUT at all?

So if you used a 1:10 SUT, that would work because you would still be OK as far as the ratio of output R to input R. (If the MM phono stage provides a 47K ohm resistance at its input, a 1:10 SUT would result in the cartridge seeing a 470 ohm load, where the load is equal to the MM load resistance (47K) divided by the turns ratio squared, which is in this case, 100. 47,000/100 = 470 ohms, which is a bit more than 10X the 41 ohm internal resistance of the cartridge. However, the phono stage would then have to handle the nominal 9mV output of the cartridge plus SUT. Actually, most MM stages can do that, but beware of overloading the phono stage, because 9mV is correct for a specific stylus velocity. On complex music or during crescendos, the output of the cartridge might far exceed 9mV, and the stage might overload on peaks.

It’s impossible to help with your question about using a SUT with a Benz Glider, because there are so many versions of the Glider. Can you be more specific? What is the voltage output and what is the internal resistance or impedance? The original Glider was a high output MC. I found it underwhelming.

That ratio of voltage output to coil impedance is better known as “current”, in Amperes.

What’s written here is hardly of statistical significance, even if your casual observation is accurate. For one thing, the topic of “what cartridge “ as posed here usually is to a price point of $1K or less. The top Benz cartridges ain’t cheap.

Isn't the LPS and some others in that series still well regarded by many?  And HOMC fans still mention the Glider in whatever iteration (though I owned two and did not much like either).  Maybe Benz is not sliding.
