Sorry Juma

Yeah, I think Nelsons suggestion was different
I know I saved it
will try to search a bit deeper

hmm, I have saved so much I cant anything
might be that it was actually your schematic that was posted back then

All of those will work fine. I think mine just had the fewest
parts.

"you probably mean cascoded input stages, not output.

Cascoded output stages are dynamic allright, but there's sort of a veil around it, ime.
Example is Mr Thagard's A100 design, early 90s, with guidelines from Paps.
(still haven't stumbled on someone else who built them though)"

haha-the comment was about output stages! Check the A75 article.
Never heard of the A100 -- was that the design described in the A75 article that was modified to become the A75?

Unfortunately, I don't know if I've ever listened to an amp with a cascoded output stage---if only I didn't have to work for living. I think a cascoded F5 would be something to hear.
