The SUT I used include Cinemag 1254 transformers wired at 1:10 for my Lyra Delos.
It sounded louder because of the extra resulting gain and really good but ultimately not as refined overall as my Sutherland fully active.
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.

Whether a cartridge is a 'voltage' or 'current' generator simply comes down to the load you present it with. Make the load an open circuit (volt meter) and it will deliver max voltage and essentially 0 current. Make the load a short circuit (ammeter) and it will deliver max current and 0 Voltage. Without a clearly established loading criteria, the discussion becomes one of futility. dave |
Dear @drbond : I think that if some one as me and maybe you re-read the Palmer explanation where @holmz added several technical characteristics maybe you can be less " worried " about.
The amps explanation linkes is wider and as I said holmz expanded on it. Now, do you think that Palmer does not knowed all the theory behind about? , I'm totally sure that he knows but not only that he laborated with for over 20 years.
Now, maybe you have a " hide card " or you have a specific target behind your links. Good, but if you have dudes just contact that gentleman or even better and invite him to share other kind of technical explanations on the issue. Don't you think could be better?

Here’s my current assessment, which has been nicely summarized by @intactaudio : basically, the cartridge is naturally developed as a current generator, however for the past decades, phono stages were created to unnaturally transform the cartridge into a voltage generator by adding the load in the phono stage. However, when the cartridge operates as a current generator, no external arbitrary loading needs to be added to the signal created by the cartridge. So, it seems, based on my limited knowledge, that the current based phono stages would be most naturally associated with phono cartridges. |
Thanks. There are better SUTs (for more money), but the 1254 is indeed a good one. I was afraid you were using a 3440 but that's not the case. A good mark for the Sutherland, indeed. I'll have to try one someday! |
