SUT into MM input section of Solid State Phono Stage

Hello,

I was wondering if any of you have experimented with using your Step Up Transformer into the moving magnet section of your solid state phono stage?

If so...

what was the step up ratio you used?
what was the mV output of the cartridge you used?
which solid state phono stage did you use?
did you find that the SUT into the MM section sounded better than just using the moving coil input without an SUT?

I ask because I just experimented with using my Tango SUT into the MM section of my solid state Forte FP-1 and have found that I prefer that over just using the MC section of the Forte.

Best Wishes,
Don

@no_regrets Yes , i have used a Entre ET100 SUT wiith a Roksan Reference phono which is solid state op amp based and i prefer it better than through the MC setting in this phono stage.

Not sure why do you think most people use tube phono stages? I think you are wrong. I’ve been using SUT only with Solid State phono stages. I must say that current-injection phono stages are much more impressive than SUTs and MM phono.

What must be matched between a SUT and the cartridge is the SUT gain to the cartridge output level, this is the main issue and not impedance loading.Any SUT with the rigth gain can works with any cartridge with the adequated output level it does not matters its impedances.

This is at best misleading.  I agree 100% that the sole purpose of the turns ratio is level matching.   It is best to match a SUT for both step up ratio and cartridge impedance.  Taking the two extremes of a 2Ω and a 40Ω, a 2Ω cartridge feeding a SUT designed for 40Ω will have bass response down to the single digits and show a pronounced resonant peak at some point (hopefully) above the audio range.  Going the other direction and using a SUT intended for a 2Ω source with a 40Ω cartridge will result in inadequate low and  (possibly) high frequency response.

D@intactaudio : That’s how the SUT react not the cartridge. I think that you can do what you posted ( dedicated SUT. ) because you make your own SUT. I’m talking of normal SUT and I own quite a few that I tested in a very high resolution system and what you posted I just can’t detected.
Your post appreciated.

Dear @no_regrets  : I did it and time to time I do and my active high gain phonolinepreamp is a little better.
