IMD is a real problem only with dynamic audio processors.
"In practise, the IMD side effects might appear very differently. Gently applied on rather dull signals they can even produce a sort of "exciter" effect and brighten the overall signal perception. The other way around, most implementations which do not try to avoid IMD tend to have such brightening effects but the other side of this coin is the perception of harshness, unfortunately."
As a rule of thumb if you have more than 40 dB of 'intermodulation free' dynamic range with any three arbitrary equal amplitude audio tones you can hardly hear any difference.
Any 'honest amplifier' has at least 40 dB of intermodulation free dynamic range when producing 70-80 dB SPL in the listening room.
If this is not the case it should be replaced.
