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?

Thanks for your response. If this is true, then it should not be difficult at all to change RCA jacks to XLR jacks for both input and output of SUT then. Hmmm.. I need to find somebody who knows how to do that. I wonder, would that in anyway affect impedance of SUT?

Do check with the websites of Lundahl and K+K Audio, Sowther, Jensen or Tamura. You'll find lots of schematics for various SUTs and will see that most all of them are balanced by nature and fairly easy to change from RCA to XLR. Do browse some of the Audio Asylum or other DIY-sites for easy to follow description on how to do.

Check with Jeffrey Jackson of Experience Music. He can put together a set of balanced SUTs for you - using Intact Audio iron - some of the best iron there is.

Also, check with John Chapman of Bent Audio. John has recently adopted Intact iron as his iron of choice.

Both of them are top-notch fellows whom I know and like. I'd be hard-pressed to favor one over the other, although Jeffrey's business model more oriented to doing "one-offs" than John's is.

Disclaimer - I know both of them well, but am in no way involved in their business.

Cheers,
Thom @ Galibier

Check out Bob's devices. He'll build one with XLR connectors upon request.
