thanks

the OpAmp_Distortion.pdf I have before is only 16.4 MB
so I am glad to get this version, too
The new version has got 279 pages (the old 222 pages)

The document was updated with a few discrete opamps. As expected, the results on these discrete opamps are quite poor.

Yeah. You gotta pay big bucks to get extra distortion thrown in

True, but don't they sound great? Especially when wired with 6 nines, cryogenically treated, unbleached cotton insulated silver wire?

If you name these discrete op-amps something like "sun" "moon" or "stars", it gives them magical properties. Maybe someday science will catch up with what's really going on here .

Our old model 50 workhorse FET discrete op-amp (c. 1970)probably blows the doors off any of these. Unfortunately I can't locate one for him to test.

Science will Never Ever fully catch up
with All The Magic & All The Religious Beliefs within our minds.
Believing it will, this is just Another Illusion of your mind.

Better than the 797? I'd like to see a schematic of this beast if you're willing to share it.

I meant the new discrete additions.
