All these things can be covered by a good phono pre-amp with adjustments for such things.
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.
That is also how I generally thing of them as well @erik_squires - but they are also a current converter to some extent… and the current coming in gets changed inversely proportional to the voltage change. And… also they (SUTs) work on magnetic fields so they are a current device.
@drbond Maybe think of a 10:1 transformer as increasing the winding on the cartridge by 10x? I am still a bit uneasy as the cartridge is more of a current generating motor than a voltage generator.
Pretty sure one cannot be a fan of Sutherland, and other trans impedance phono stages… and simultaneously a fan SUTs. Maybe it is possible. |
Holmz, please read my long post and Larry’s too, near the top of this thread. Of course transformers transform both voltage and current in direct proportion. The product of volts X current on the primary equals the product of volts X current on the secondaries. Don’t make the subject harder or more vague than it needs to be. |
