Default Looking for discrete buffer circuits capable of several watts or so...

Hi everybody, I'm Anthony, and this is my first post here. I have done a lot of work with Szekeres style amps, and fiddled with op-amps somewhat, but after starting on my YAHA amps, I have been looking for solid state alternatives to op-amp based buffers for output stages. Szekeres is great, but I'm starting to get interested in complimentary pair DDB topologies. The ddb by Walt Jung looks cool, although I've read somewhere that there've been output mosfets swapped in. Does anyone have the schematics for those? Any help would be greatly appreciated.

I saw this from LME49600 datasheet. 2000V/us, 180Mhz, 250mA output device.

Just found 455 replies to search on discrete buffer.
Try reading some of them.

Oh, everywhere else I've been it means Discrete diamond buffer.

Since mosfets are biased differently than bjt's, how would one change the circuit in order to use them?
