The M3i has a Class A preamp with its own, independent power supply with separate transformer windings. It is, in effect, a separate Class A preamp with a stereo power amp, in a single elegant package.
We have engineered the M3i to be as smooth and seamless in operation as possible. For example, it has ultra low noise silent switching, perfect volume control matching even at very low levels, and outstanding power amp stability margins. The M3i may be modest in price, but it achieves huge ambitions and offers true high-end performance.
