Joshua, that is a long time ago.
It also depends a lot on the layout and the PSU.
Ones the technical data of a certain topology is better then what the ear can differentiate other factors come into play.

Very nice work K.

It seems to me that the approach taken by this buffer topology is also applicable to half / full Diamond Buffer output Power Amplifiers... I wonder if Hawksford tried something ?

But I'm not sure I agree that this circuit doesn't use feedback. The CM is the feedback mechanism, only it senses current of the output device instead of voltage (nothing wrong with that). Anyhow, it's only semantics.

Default Thanks sikahr

Thanks sikahr for making these available (and so cheaply too, just learned something new with dirtypcbs). And of course, to keantoken for the design.

Is this a clear cut case of theft, or will you pay Kean for His circuit design?
