antinn, In your quoted paragraph, I think they are using "Watts" as an expression of acoustic power or energy. On that assumption, and wanting to know how acoustic watts is defined, I found this on Wiki: "Sound power or acoustic power is the rate at which sound energy is emitted, reflected, transmitted or received, per unit time.[1] It is defined[2] as "through a surface, the product of the sound pressure, and the component of the particle velocity, at a point on the surface in the direction normal to the surface, integrated over that surface." The SI unit of sound power is the watt (W).[1] It relates to the power of the sound force on a surface enclosing a sound source, in air. For a sound source, unlike sound pressure, sound power is neither room-dependent nor distance-dependent. Sound pressure is a property of the field at a point in space, while sound power is a property of a sound source, equal to the total power emitted by that source in all directions." It's not an easy concept to grasp.
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.

It is now within this thread, having evolved from a useful supply of information, that most visitors would like to take something from, to a very unusual concern, where a minuscule quantity of individuals concern themselves. The presenting of a Math as the reasoning to impose the notion that another method is lesser and not the optimised circuit is really starting to taint a well presented thread, as result of its former contributions. The thread now is grounded with ones intention to attempt to impress their Mathematical Preference as being the better over another. This attempt to hold centre stage, is being met by others, with a countering of this very obvious intention at large, especially where the Math has been used as the support for the notion being proposed. The Mass of Users of Devices as a Listener, do not care for such a Topic of Discussion. As said many times, the Judgement made on a device is commonly born from there being an attraction toward it, either through Clever Marketing, Word of Mouth, Aesthetic appeal, Cost, Discounted Cost, Gifted, Impact Made During a Demonstration, Stimulus Created, Attractive Experience Worthwhile to Maintain. Somewhere behind all the above that coming together in one permutation or another is Math. It is quite difficult to see where the individual place much care on the Math that is not the commonly used criteria for matching a Device to another Device. The Topic of Math most recently under discussion and now dominating as a Spoiler, is as far to the extremities and circumscribed in content, as can be imagined, when comparing the content to the OP's original request for information. |
Respectfully I’ll offer an alternative… I would say that that “linked info” falls squarely within the second paragraph of the OP’s ( @drbond ) question.
Even the OP’s first paragraph mentioned wanting to understand the theory behind a SUT. So the beauty of Maxwell’s equations sort of is a real manifestation of scientific understanding becoming an engineered product. While many an end user may not want to understand it, and would rather have a recommendation of one particular SUT and similarly one specific cart… it is none the less a true thing of beauty how both the cart and SUT work. |
+1 @fuzztone …..it’s about gain, simple. |
