Hey guys..

Since I've been looking around headfi, I've seen the term 'diamond buffer' used to describe most peoples favorite type of output stage.. I always figured it was some fancy output circuitry...

However, once I ACTUALLY stumbled onto a schematic, the one I saw was just a complimentary common collector cascasde... The same topology I used as the output stage for an opamp I designed.. Then I later saw another circuit listed as a 'diamond buffer' and it was just a diode biased complimentary common collector output.. Pretty much the generic class AB output stage..

Is 'diamond buffer' just the catch phrase 'round these parts for a discrete AB output stage? Or am I looking at the wrong schematics or missing something?

I think originally people are talking about Walk Jung's diamond buffer, but there are many "interpretations" of it and modified designs. The principle is mostly the same though. Take a look at the diamond buffer for the Millet Hybrid, also a nice design.
