OPAMP rolling (discrete vs IC) evaluation/presentation by Tom Christensen

Hi

Not sure if you follow along with DIYAudio/BAF but this presentation may be of some interest to you.
Tom's one smart dude with lots of experience. He was kind enought to post his slide set for us to view. Mark J. has posted his too on his free matching jig pcb.
Tom has taken a jelly bean part like the LM3886 and turns it into a number of hi-performance amplifier designs and other audio designs.
Ever wonder why a lot of smart EE's circuit designers never discuss sound quality of their designs?
They let the instrumnets and others speak for them.
Folks ask me how our designs sound? I always say "good", or they would not be evaluating it in the first place.
I want to hear what you have to say.
Nelson Pass says "its entertainment not dialysis"
Some even get a chuckle out of Burr-Brown tagging their audio IC's as "sounds plus" 🙂
It's the marketing and sales that put their spin on it.

Enjoy your enlightenment if you are able to comprehend some of the finer details of circuit design and analysis.
