AFAIK it isn't. Not even impedance balanced unless the impedance of the active pin is _very_ low indeed. I very much like Dave's idea. Given the price the Tetramic is a good deal. It's a bit too noisy for some applications but quite OK for many. Its main drawbacks for me have been the fragility and the less than satisfactory shielding of the cables and connectors. Just fitting a full-size XLR-M6 to the tube body would probably solve most issues.
