@mdalton It's funny - you've got Fern and Roby and Rothwell SUTs. I think both use Lundhal transformers. These I would definitely like to hear - my hunch is that the presentation is more 'modern'. Maybe a nice balance for the SPU! I got my HM-3 SUT from tube-amps.net - goofy site, but the gentleman was very professional and the product is very well built.
@mdalton Hey there - I mean the upshot of my experience with the SUTs has lead me to the Hashimoto HM-3-based SUT from a guy in Michigan. Pricey, but oh wow the clarity you can get from a damn conical stylus! The other two - Cinemag-based from Ned Clayton and an entry level Audio Note UK unit that I got used on Audiogon - I guess I'd describe as variations on a theme, with the Cinemag based SUT having a slight 'opacity' to the sound, which is pleasing, for sure. Maybe tone-forward is a way to describe it. I have new tubes in my phono stage and so I'll try swapping them in and out and see if anything jumps out at me.
