It has recently been postulated that power amplifiers with high open-loop output impedance and large feedback factor are more likely to produce intermodulation distortion at the loudspeaker interface (IIM). With the aid of computer simulations, this possibility is examined in the context of contemporary amplifier circuits. It is found that there is no fundamental reason for increased IIM in such amplifiers given proper design.
