I'm new to Step Up Transformers


     I've recently become aware of the existence of SUTs (step up transformers). My initial thought was " why do I need an SUT when my phono preamp (Zestos Andros PS-1) has a circuit for Low Output MC cartridges?
     But many people seem to think that an SUT plugged into the MM channel of the phono stage will be a massive upgrade. I'd love to hear the opinions of anyone who has experience with SUTs. Thanks!

"Which SUT are you using with the Hyperion ?

Have you compared many ??"

My current favorite is the Consolidated Silver Wire SUT.  I also have a Bob's Devices.  Both are external and are 10:1.  I also had an internal one in my previous Conrad-Johnson phono stage.  That covers the last 10 years or so.  I've been at this a long time and have had others, Ortofon, for example, Denon too, years ago, but with different cartridges and TT/arm setups that hardly are pertinent today.  I should also mention that for several years now I have settled on Audio Sensibility Statement silver interconnects.  Interconnects in and out are pertinent and consistency is important in evaluating differences.

When it comes to hifi hobby, matching the correct stuff together is what creates nice synergy. One might have 2 excellent sounding pieces but they might not sound great together. Exploring external SUT’s is just one of the many unique things people do to get the best performance from their vinyl setup. I own 7 SUT’s and have listened to about 15 different ones in my system. They all sound very different.  I heard some very nice ones but in the end, I settled on a SUT that uses 50’s transformers made by Thordarson. Just like everything in this hobby, there is a world of SUT’s and makers of them out there for you to try. No easy way around this once you open that door. Good luck and you’ll see that they do make a difference. 

rmcfee, I’m glad I am able to share my experience with you about SUT’s. Mine journey began when I first purchased a Denon step up for my Denon cartridge. I then picked up a Ortofon and after an expensive active tube based Klimo. From there I started to realize that these things make a difference. I listened to my friends AudioNote and even though it worked great in his system, for mine it was too clean and lacking body. In his setup, it sounded great. I listened to a bunch more till I found around 7 that I liked best for me. Don’t think that because a transformer matches well in someone’s system that it will sound good in yours even if you own the same cartridge. Your system (cables, tonearm, preamp, listening room) is unique and you’ll need to hear it in your system and find the best sounding and matching SUT’s not just for your Cartridge alone, but for the system. If I were you, I would begin with searching on the web what the majority recommend what SUT’s with your cartridge. You might get a few and find them very good, but if you keeping going, eventually you’ll find the one that matches really nice with your system. 

To me, the real purpose of SUT's is to allow the use of a low output MC cartridge with a MM only phono stage. I recently replaced the McIntosh preamp in my main setup with the new Marantz AV10 processor.  It has terrific specs and very low noise, but it only has a MM phono stage, while the I have a low output MC cartridge on that turntable.  So I bought a SUT so that I could connect directly to the phono input on the Marantz.  It works just as anticipated, but I would not say it is better sounding than using the same table' and cartridge going to the MC input of the McIntosh.
