"Differential Drive Amplifier"

I was wondering if anyone can tell me (in laymans terms) what type of design this is, how it works and the benefits over conventional type's, like in Mr. Slone's books?

I'm getting ready to build my first amplifier and I have purchased 2 of Randy Slone's books on the subject to help me out but no where in his books and or on the web can I find any info about this type of a design anywhere else other than the companie's site.

Thanks,
Jay M. 😕

It's just a Balanced input / Balanced output amp. Nothing special.
