SUT - electrical theory and practical experience

Some vinyl users use a SUT to enhance the signal of the MC cartridge so that it can be used in the MM input of a phono stage.  Although I don't understand the theory behind it, I realize that a SUT should be matched individually to a particular cartridge, depending on the internal impedance of the MC, among other things.  

Assuming an appropriately / ideally matched SUT and MC, What are the inherent advantages or disadvantages of inserting a SUT after the MC in the audio chain?  Does the SUT theoretically enhance or degrade the sound quality?  What does the SUT actually do to the sound quality? 

Thanks.

SUTs are all about the quality of the transformers. I run a Bob‘s Devices Altec Lansing TBB103 and can confirm that using the gain stage of my Zyx Artisan instead leads to a major deterioration from my Zyx Universe.

yet another very dogmatic thread, this. If SUTs are evil, why do designers like Ortofon, Yamamoto, shindo et al use them rather than active circuits? Surely there are many ways to Rome and implementation matters.

I find it quite incredible how many people on A‘gon indulge in absolutist and arrogant language without any knowledge basis for their argument. Don‘t be discouraged by them, your contributions are always well founded and instructive. Thanks for that.
