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.

@rauliruegas,

You have taken what I said completely out of context.  What I was trying to say is that based on the two values you provided which was only the slew rate and the bandwidth, that by the equations the amp would become unstable at a specific voltage with one caveat (as addressed in the documents I linked) that designing the amp for peak voltage above that threshold maintains stability.  I also linked the Spectral specification where they specify all three values - slew rate, bandwidth and peak voltage.

So, I never stated that your preamp would be unstable above 1.5Mhz and now better appreciating how you interpret these items, should I ever conversate with you again, I will endeavor to be far more specific to prevent any misunderstanding. 

Peace on Earth and Good Will to All  

 

@antinn , yes often I have those kind of misunderstood and yes is my fault but not you or me losting nothing with the posts other tha your gentle time. Sorry for that.

@atmasphere  , that's what you wished but JC never came to support your tale. In that regards you are very bad looser, sorry.

 

Peace.

The following Bracketed Teext can be found on Page 4, it won't be difficult to see who posted it.

It looks like the references to the Sugden Model fell flat, and this has been the next arrows pulled from the quiver, as an attempt to collapse the Thread.

" trolling " especially demarcated. Passing the Buck 'isn't cricket old chap'. 

( Maybe just maybe drbond is just " trolling " in his latests posts. )

As said, a indicator of a collusion being in place to derail the Thread, seemingly a reignition of a previous slur and a attempt at accusing the OP of being disingenuous.

The OP has been present throughout the thread and shown appreciation of much that has been shared in support of their made inquiry. 

In relation to the Thread Title '   SUT - electrical theory and practical experience' drbond is the antithesis of a " troll ".

that's what you wished but JC never came to support your tale. In that regards you are very bad looser, sorry.

Aside from the very obvious turnabout/contradiction from your prior post to me, just so you know, I've never asked JCarr to give me any support- I never felt any was needed and still don't. So how do you arrive at the 'looser' comment?? You already admitted I was right, confirmed what @intactaudio had also said.

So could you just lay off the trolling?? How about for the next shall we say, 3 days?? Have a good time over the weekend- seriously!
