SUT into MM input section of Solid State Phono Stage

As a fact the comercial SUT are designed that way where ( example. ) 3 ohms of impedance means high gain between 30db-40db .
I never seen a SUT with 36db of gain for 40 ohms impedance cartridges.

Normally cartridge internal impedance value has an inherent relationship with its output level and the gain it needs .

SUT gain is critical to match a cartridge because if it's to high normally will overload the phono stage and if it's to low will develops some kind of noise and a little dull sound.

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

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.

@no_regrets  : "  what you are experienced is something that happens to often and depends mainly of the quality level design of the active high gain stage in the phono stages and not because it's better the SUT/MM combination. "

So sometimes sounds better with the SUT sometimes not. Even that your unit was designed by Threshold is an entry level and obviously not the best active high gain design and that's why your frefer the SUT.

Btw, what other gentlemans as @lalitk and @fuzztone posted here is not exactly that way because it's not the cartridge and the SUT impedance what must be matched this is totally false.

A LOMC cartridge is not affected by SUT impedance, it's insensible to loading impedence changes.

   " Loading the transformer does have an effect on the load seen by the cartridge, but any change in sound quality is more likely to be due to altering the performance of the transformer, not the cartridge . "

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.

Low knowledge levels in that subject makes that audiophiles post wrong information/advises.

So, just continue listening where you are satisfied.
