Conventional wisdom would have us believe best results are obtained via simple solutions. The simpler the solution the better and cleaner the outcome.
I find simple solutions are often the most difficult to accept and inevitably the hardest to find.
How many times have you gone round and round in search of a solution only to finally land on what, after the merry-go-round of effort, seems suddenly obvious?
A DC blocking capacitor is a heck of a lot simpler than a complex DC servo-eliminating circuit.
When a magician saws a woman in half or causes their assistant to seemingly vanish we often struggle with complex theories to explain simple illusions. It is in our nature to assume complexity when the simple answer does not present itself.
Too often I have watched complex equipment solutions applied to less-than-great stereo systems when all that was really needed was better setup.
Digging down to the point of simple is a complex task.
