Default Supersymmetry and single gain stage

Excuse a newbie question, but I want to ask if it's possible to use supersymmetry in a circuit with a single gain stage, such as the output part of jwb's DAC (http://atari.saturn5.com/~jwb/43122.png bottom right).

Hi prune

I have only tested it in my cdplayer, the sound is great.
The reason I havenīt implemnted it yet is lack of time, itīs a little trickey job.
Inputs, as in the scematic you just pointed to, is after C7 an C9.

Actually I changed the Zener to a LM329 an R14 to 220 Ohm, like on the photo.

The swiches and the parts around, one resistor and one cap at each schwich, is only for testing balanced versus unbalanced input, they are supposed to be remooved afterwards.

I don't understand what makes this circuit supersymmetric.
Is this the latest version in the zip file you link to?
