Hi Tom,
If you are concerned about length, the output impedance of the CJ GAT is 100ohms and is designed to drive long runs (it actually is part solid state, part output tube buffer)...as i understand you get the lower output impedance of a SS with its ability to drive longer interconnect runs? Might be the same with the ET3...do check if you are interested.
Meanwhile, if you are set on balanced...the ARC Ref5 or Ref5SE are both excellent and for the money (particular the 5 second hand) is excellent as well. Good luck! You've got great options...enjoy!
