McIntosh has released its MC312 power amplifier, which replaces the old MC302 power amplifier. Although the new model has exactly the same continuous power rating as the older model (300-watts per channel into 8Ω, 4Ω or 2Ω) McIntosh says that it has 0.5dB more dynamic headroom, primarily thanks to a doubling in the size of the capacitor bank.

This increase in filter capacity and dynamic headroom means that the MC312 will be even better-suited to handle wide dynamic swings in music,’ said Philip Sawyer, of Synergy Audio Visual, which distributes McIntosh in Australia. ‘But the increase in filter capacity also has benefits in reducing the possibility of distortion and improving the bass performance.

The fact that the power output is identical irrespective of load impedance is due to McIntosh’s use of autoformers in the output stages. The autoformers are located in enclosures that are capped by covers containing glass inserts that show the wiring diagram for each transformer.

Another difference between this new MC312 and the older MC302 is that this new model has both unbalanced and balanced line outputs, so you can use multiple MC312s to drive bi-amplified and tri-amplified speaker systems, plus it has McIntosh’s ‘eco-friendly’ power management system. Visual design changes include direct LED backlighting for front panel illumination, which McIntosh says results in improved colour accuracy compared to the incandescent illumination used previously. 

In common with many McIntosh amplifiers, the MC312 has McIntosh’s ‘Power Guard’, ‘Sentry Monitor’, and ‘Power Control’ circuits, together with the familiar polished stainless steel chassis, black glass front panel, aluminium end caps and blue power output meters. ‘The McIntosh MC312 is a great choice to power virtually any home audio system, and will deliver years and years of musical enjoyment,’ Sawyer told Australian Hi-Fi Magazine.

In Australia, the McIntosh MC312 power amplifier sells for $14,995 (RRP).
