SUT vs. Phono preamp

if you really want to understand SUT’s, here is a reference for how they work and how to choose one.

personally i have 2 SUT’s right now (one with copper windings and one with silver windings) in my system i’m demo’ing. these guys.

the advantage of an SUT 'in theory' is lower noise, and 'in theory' greater micro-dynamics, than a head amp since the SUT is passive. in essence; a head amp involves an additional amplification stage which 'in theory' always will add some noise......and reduce the sense of naturalness and ease. as always; there are no absolutes; these concepts depend on degrees of execution. SUT’s are not always better, and head amps are not always worse.

it depends.....

I have 5  LOMCS, one phono preamp and one SUT. Actually, I do not notice much difference between  the phono preamp and the SUT, but I just wanted to know a little more about the theory behind all this; your responses so far  have helped  greatly. 

@billwojo,

I had a Denon AU320 SUT teamed with my ZU-Denon DL103 and I didn’t particularly like the sound as it sounded kind of flat.  I sold it and bought a Bobs Devices SUT with the Red Cinemag transformers.  The sound was clearer and much more involving.  

What is your phono stage @boofer ?
