Musical Fidelity M3i Amplifier
The Musical Fidelity M3i Amplifier uses similar drive circuitry to their most expensive amplifiers.
The Musical Fidelity M3i Amplifier has low distortion, typically less than 0.02% from 20Hz to 20kHz. Most amp manufacturers do not bother to measure high frequency performance. They claim that because you cannot hear such high frequencies, the distortion and other artefacts are irrelevant. We could not disagree more strongly. We think that how much high frequency distortion an amp has reveals the inherent rightness (or wrongness) of the whole circuit design and printed circuit board layout. Driving loudspeakers is demanding for any amp, and we believe that very low distortion into a wide range of loads over a very wide frequency range is the basis for a proper design. The M3i delivers 76 watts per channel into 8 ohms and 137 watts into 4 ohms, a near-perfect result that shows that the Musical Fidelity M3i Amplifier will perform well even when driving power hungry loudspeakers.
The Musical Fidelity M3i Amplifier 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.
The Musical Fidelity M3i Amplifier has been enginered 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 Musical Fidelity M3i Amplifier may be modest in price, but it achieves huge ambitions and offers true high-end performance.
