All of the really cool parts are duals, and quads crosstalk too much (If you really need a quad, use the AD713KN. Awesome!) For duals, look at OP275 or LT1113CS8. Stay away from junk like 1458s. Think of a TL072 as the BOTTOM rung of the food chain.

Man stop stop plase bee halted, You are long away in the spaceright now
I have designed an entire system with among many the LM13600 and i think
you are on some thing alkoholic
rhigt now.

If you where right on the CA3080/LM13600 issue why would so many
manufacturers have build systems on them?
And there are still manufactures today who build on CA3080.

And finaly what do you mean with "  im a  former Moog designer for 20
years. Bad or God? :)
