We were particularly impressed by the sense of solidity and warmth from this amp. It certainly punches above it’s weight. We listened with the Dynaudio Emit 10 bookshelf speakers and were impressed by the grip and control. We upped the anti with some Spendor A5R floorstanders and were not disappointed; the Musical Fidelity handling the better speakers with aplomb.

The M3i boasts trickle-down technology from our mighty Titan flagship, plus other high-end touches such as solid metal controls.

The M3i delivers 76 watts per channel into 8ohms and 137 watts into 4ohms. This means the M3i will can drive a wide range of speakers, even power-hungry models.

Further flexibility is provided by the M3i’s excellent connectivity, which includes six line-level inputs and switchable home-theatre throughput.

It features a Class A preamp stage with its own, independent power supply, coupled with a discrete pair of power amps. In effect, this means the M3i offers the performance benefits of a pre/power configuration with the compact convenience of a one-box design.

The final word goes to The Absolute Sound, whose review of the M3i stated: “Its performance is rock-solid, it’s sonically well-rounded and it’s comfortable with a wide array of speakers. And it’s all served up in an elegant, no-nonsense package”
