Will Step Up Transformer Improve the Sound Quality?

I'm wondering whether a step-up transformer would improve my analog signal path.  I have a VPI Prime Signature with a Dynavector 17D3 Karat cart.  My phono stage is a Parasound JC3+.  The rest of the path is a PS Audio BHK Signature Preamp and a Pass Labs X-150.8 amp into Spatial Audio M3 Turbo S speakers and dual REL S/3 SHO subwoofers using Audience cables.  I am looking for advice as to whether adding a SUT would markedly improve the sound.  I am also looking for recommendations as to which SUT's would work well in this system.

Like everything else, it depends.

First thing is how your phono stage is made. Some have lots of gain built in, and are nevertheless quiet - when I DIYed my phono/pre, I built in lots of gain, and spent time and money to make it quiet. Dead quiet. I also built in a very fine SUT, the top silver Lundahl, because I have a Miyajima mono cartridge, and it hums unless isolated by a transformer.

I marginally prefer the electronic amplification to the Lundahl SUT (which, by the way, is the best I've ever heard, including a 10K unit) because it's just a touch clearer and just a touch more dynamic. But that's with dual unobtanium input devices in parallel to reduce noise. Otherwise I would definitely prefer the Lundahl. YMMV

More noise? Less noise if you shield carefully and keep AC far away. Or so it seems to me.

Of course if you put an SUT near a high voltage power supply you are asking for trouble.
