It seemed to me that servo isn't a problem since, in this "bridged balanced", the current sources are share by two fets.
But I didn't really understand how feedback worked because here we are dealing with single-ended inputs. (should we look at it like an half of Pass's susy ?)

Su-Sy is a simpler topology, and leans towards single ended gain/power stages where KG's dynamic amp is all push-pull from input to output. Su-Sy is also more about how the halves of the amp are combined into 1.

link to pass Su-Sy article you can read the original patent on google patents.

When talking of susy, I was more thinking of something like this. I hope I will try this version of bridged dynalo one of these days, it looks really interesting.
