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.....
