Anyone heard of Silvercore SUT:s

At the recommendation of a friend who designs amps and preamps, I bought the Silvercore mc and then upgraded to the Silvercore pros. I guess that means I think they're good--I was primarily using them with an Ortfon 90th Anniversary SPU and Ortofon Synergy SPU, although I also used a Koetsu Rosewood Platinum. No hum problems at all, in fact deathly quiet, but very dynamic sounding. Previous transformers, not directly compared, were the top of the line Audio Note and the Auditorium 23, both of which were excellent (but I went through a short phase of using a solid state phono amp, and didn't need a transformer at that time)

I'm using the MC Pro, but "naked"--first I used it as the stepup in an LCR Cole, and it has been sent to JC Morrison for use in a phono stage of his own design that I hope to receive soon. Prior to that I used the Silvercore MC in conjunction with my (then) Zanden 1200 phono stage.
I am also using the Sivercore Preamp 2 as my line stage, but they were kind enough to build it with 24 steps on the volume control.

I don't know if you could still get them without the case or not--he has an American distributor, oswaldmills, I think, who might be able to help
I have no experience with the 1:10

I only used the Cole with the Silvercore SUTs, so my experience may not be representative. I went from a Messenger to a Zanden (or maybe vice versa) and then an FM Acoustics 122 to the Cole and do not feel that I enjoyed music any less with the Cole than the others. The only problem I encountered was that the Cole was more prone to picking up hum than the others with low output MCs. I think that the Cole (and Vinyl Song) are great value for the money.
