It's really quite simple. Every guy who can figure out how to use a soldering iron is suddenly an amplifier designer just as every guy who can build a box that doesn't fall apart is suddenly a speaker designer. Do you dismiss vehicles driven by internal combustion engines if there are mostly a lot of Yuogos out there? We'd all still be riding in horse drawn carriages if they did. You can bang you head against a wall all night for months on end trying to solve the problems in calculus describing feedback circuits...or you can just add a few resistors to a circuit and hope for the best....or just forget the whole damned thing and say it's no good.The question for people like John Curl who are serious about designing amplifiers or anything else where far more than money is involved in solving a problem is how do you know when the thing you've built is doing exactly what it's supposed to do. Is it when an amplifier "sounds good" to somebody's way of thinking? To a consensus? Do you throw away a thoroughbred race horse because it won't pull a milk wagon? Do you dismiss a Porsche because it can't pull a house trailer? Is the purpose of an amplifier to make the sound of lousy speakers playing antiquated recordings on phonograph records palatable? If it is, then you might as well just throw up your hands in disgust because you will never get there, someone will find fault with every one you make no matter how it works. That's the curse of designing to please "subjectivists."
