Amplifier memory distortion application
That's an old site I had maybe 20 years ago. I had forgotten about it...

In retrospect I guess this memory distortion thing was just a red herring. This kind of stuff pop up periodically in the audio community, someone finds a magical reason that explains everything, it gets popular then is forgotten then it starts all over again with something else.

Sure, if you want an opamp with quick settling time to high precision and low thermal tails then you need an input stage that doesn't get any temperature imbalance, especially when it handles strong input signal. But is that important for audio? Probably not!
