Default Power Amplifier Circuit Topology according AD846

Are there commercial products on the market or are there diy projects like discrete opamps, where this topology is in use?
Most interesting feature is the fact, that here (in the inverted mode) the signal pad goes in to the emitters - thus no parasitic capacitances have any influence.
Thank you for advices.


Concerning the AD846 there are follow threads here on diyaudio:

844 works on same idea - current conveyers into diamond buffer. Just a bit more sophisticated conveyers.

Thank you. Maybe Jan Didden's current Conveyer power amplifier project for German's Magazine "ELEKTOR" (PAX-AMP?) is such a topology in a discrete version. But I am nut sure. Who can upload the article?
Here on diyaudio I have found this:


An inverting current conveyor approach

Current conveyor as a voltage amplifier

The InSense Current Conveyor
