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.

I believe loading of a MC cartridge has a dramatic effect on the electromechanical behavior of the cartridge but that is a topic for another thread.

@intactaudio Yes! You and I are on the same page here.

Dear  @atmasphere  : "  I am in disagreement with Mr. Der Veen on this topic.  "

 

Rothwell too and I learned that almost 20+25 years ago.

Exist at least 4 long threads about in this forum, in all were very hot dialogues and that the end even that in theory exist the phenomenon that the cartridge cantilever could " suffer " of some kind of " stifness "  and even if happens Wynn proved in two of those thread with measurements in real time that the  effect in reality does not disturb the cartridge tracking levels and the one that really could " suffers " with that load/cartridge inductance and total nettwork capacitance is the bad phono stages designs but fortunatelly today not only Phono Stages have widebandwindth but high overload levels.

@mijostyn  could tell us something about because his phono stage has an over 3Mhz of bandwindth and high overload. Something as the phonolinepreamp in my system.

Dear @drbond  : ""  to be mostly irrelevant to the topic at hand, and mostly just arguing to support his perspective,....""

 

Is it that exactly what you already did it through all your thread and why a gentleman just from the very first page posted this?:

 

"" If I didn't know you were serious, I would suspect you of being a troll based on this sentence.  ""

 

and you following posting links trying to support " your perspective: don't you?

 

In the other side please show me 3-4 posts by me that were totally " irrelevant " and if you tell me then I can learn what or not do in the future. So I'm looking for your help. Thank's in advance.

...And with that Raul has created a new branch of physics. That the cantilever is affected is a very real thing. If not- then we all could solve the world's energy problems by simply using enough phono cartridges 😂

@rauliruegas Before you implicate Mr Wyn with such a proposition, you better be sure that's what he really said! I think you'll find that he said something a bit more specific.
