True, my reasoning was based on my experience of designing intermodulation precorrectors in RF amp stages where a complementary distortion to that generated by the amplifier is normally introduced to linearize its response. This is why I said that a precorrector itself is an intermodulation generator.For the record the OP is trying to make distortion not reduce it.
+1... I recall seeing and reading more than one AES paper from Cherry about amplifier design back last century. Very instructive, but as I recall those papers were about objective measurable phenomenon.Ed Cherry presented a really good paper at the AES convention in Melbourne in 1984 which may be worth examining ("Amplifier Distortions: Audible and Inaudible"). Here he presented different styles of music and introduced different amounts of different types of distortion during listening. Most were actually very pleasing and enhanced the sound, with the exception of crossover distortion which sounded pretty objectionable.
