Sorry -- should have included the internal impedance as well. Output voltage is .9mv and Internal Impedance is 41 ohms. This is from the spec sheet included with the cartridge.

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.
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?
Good to know I got the math right lol.
Just looking into ways to get the best out of the cartridge based on what I've been reading and what the specs are. Could be that I'm hearing the best (per your opinion of it) and it's just not meeting expectations!
Thanks for your help, and apologies for hijacking the thread.
