Balanced SUT, what's available?

Currently I have ASR mini Basis that I use with Dyna XV-1s along with Ortofon SPU100 SUT with excellent result. I placed an order for ASR Basis Exclusive awhile ago and now my dealer told me to wait a little while for ASR anniversary model. I have no idea what's the difference between 2010 model and anniversary model is. Anyhow, since ASR recommends using balance phono cables for best performance. I plan to try my Ortofon SUT in single end mode vs balance mode without SUT into Basis Exclusive and see what happen. I also am curious about using balanced SUT. (Mini Basis midrange was a tad dry and lean and I prefer the added richer, mellower sound of Ortofon SUT). So far I find Technical Brain has a balanced SUT but with no information on price or data such as impedance etc so have no idea how it might match my cartridge. I assume that it suppose to work with wide variety of cartridge since Technical Brain phono only has 40dB gain so I expect most people who use Technical Brain phono would need its SUT for any MC cartridge.

Anyhow, does anybody has more information regarding this SUT or any other balanced SUT?
