Mostly I am interested in digital, but when it comes to audio, there is still some analog and with somethings there always will be.
More about this later.
Right now want to talk about the JBL discrete audio op-amp audioheritage.org
And other things like that, refusing monolithic IC's, and for what reasons and what situations?

Lots of books, no deseased, used to have audio kits. But used to have this discrete module which he called, "The Audio Engine".
Not sure if I can find specific information about his "Audio Engine". He is deceased and his web page is down. Don't know if his biz is still running.
But these Nord people look real interesting. Need to critically evaluate though there use of discrete rather than monolithic.
