I have not used the MGMC1 but do use a MGCC1 matched to a pair of MG 3.6R. A sub is essential along with a surround processor that allows you to crossover the Center channel at a high level. The center is only rated at 160-20kHz +-4dB. Mine is matched to a Vandersteen V2W. Once properly setup, you will hear very clear dialog.
