LABORATORY TEST REPORT

Before going into detail about the results of Newport Test Labs’ test results, it’s extremely important to note that for the purposes of this test, Australian Hi-Fi specified that all tests had to be conducted with both the Michi S5 and Michi P5 in the ‘test loop’. Therefore there are very few results that can be compared with Michi’s own specifications, which are gained by testing the components individually, or indeed against the results from any other audio test laboratory that has not tested the two amplifiers as a ‘combo’. This means that, in effect, we’re reporting ‘worst case’ results because for results such as distortion, the distortions inherent in the Michi S5 are here added to those of the Michi P5, which obviously does not occur if the components are tested individually.

One of the few outcomes that would not change is power output, of course, and Newport Test Labs measured the power output of the Michi S5 at 612-watts per channel (27.8dBw), both channels driven into 8Ω, when it was delivering a 1kHz test signal. It was also able to deliver this exact same power when delivering a 20Hz test signal. However, when Newport Test Labs used a 20kHz signal to test power output, the Michi P5’s
