<< lifted connection by connection, component by component from a Burr-Brown Application Note >>Not only the big Japanese majors practice this type of intellectual laziness. The so-called "Adaptive Biasing" that Levinson uses in their big power amps was taken directly from a 1981 AES paper written by (of all people!) the engineers from Sansui!
But to my way of thinking, the mere fact of using an op-amp for an audio circuit is another example of this mindset. Effectively the designer is saying "I can't design a better circuit than this." While this may hold true for cost-sensitive applications where sonic performance doesn't matter, it is a bit embarrassing when it comes to a so-called "high-end" product.
