VAC sigma triode preamp?

Wondering if anyone has any experience with these? Very little info about them on the web - they don't seem to have been reviewed anywhere. Released in 2008 as best I can tell, 6-7k range. One is available with the MM/MC option for what seems like a decent price and I'm curious. I currently run a Shindo Auriegies MM into a Primaluna Dialogue Premium amp and while I love the Shindo sound not having a remote is proving challenging for me. I've also been very curious about VAC gear for a while, been close a few times on pulling the trigger for a Phi 200. Thanks - Dave
