Re: On a different note: Response to Morricab on Amplifiers

Well for starters crossover distortion is an Anharmonic type of distortion that is mostly non-existent in Class A and totally non-existent in single ended amplifiers.

However; the main point of the post was that Class AB amps are asymmetric

which results in anharmonic distortions. If SET and no feedback amps have anharmonic distortions then they are not alone.

"What is not in dispute is that the open loop linearity of any amplifier is no where near its closed loop linearity, so to a large extent you comments are academic, if objective accuracy is a goal for the amplifer designer, as the article you quote states, that are guidelines to using feedback and as long those guidelines are observed, the beneficial effects of implementing feedback in the amplifier design overshadows the disadvantages."

Again, to whom? The oscilloscope or the listener. Linearity for the sake of linearity is NOT the goal. Audible distortion should be minimized not ALL distortion, the elimination of which is impossible with inherently non-linear amplification devices.
