Default Darlington VAS stage with optimized C dominant pole?

Emotiva is saying this of their flagship mono block amp.


Is this a good thing?

Marketing hype... that describes the most typical amplifier topology. Sounds good to a layman , to part him and his $$$'s.

There is a big difference between a Darlington VAS and a Buffered VAS. The difference is that in the Buffered VAS, the collector of the first (driver) transistor is connected to GND instead of to the collector of the VAS transistor (VAS out). This makes an enormous difference in stability and thus bandwidth, wrt C-dom. Marketing hype, perhaps. Technically mis-labeled circuit description, probably. Don't have a schematic do ya?
