M6si500 - Design and Build

The M6 500i offers prodigious power – 500 Watts per channel into 8ohms – but there's so much more to it than muscle.

The M6 500i has a high-quality metal build that gives it both distinctive style and a solid performance platform. The front panel is a bespoke, fine-line extrusion of military-grade aluminium, while the heatsinks are also custom-made for outstanding dissipation plus a fine finish.

We have engineered the M6 500i as a genuine dual-mono design. Each power amp section has its own heat sink and separate transformer, while the preamp has its own power-supply winding.

The five input sockets are connected directly to the main preamp circuit board, instead of using wire connections. This ultra-short signal path ensures ultra-low impedance from the instant sources feed into the M6 500i.

Meanwhile, each channel has 12 big bipolar transistors; 200 amps peak-to-peak performance is readily available.

In addition, a precision digital volume control – using laser-trimmed substrate resistors - ensures perfect tracking right down to very low listening levels.

Such attention to detail delivers stellar technical performance. For example, distortion levels are remarkably low – around 0.008% at 1kHz and 0.015% at 20kHz, and only marginally rising to 0.02% at ultra-high frequencies of 30-50kHz. Signal-to-noise ratio is also minimal.

The M6 500i has remarkable linearity and consistency, enabling it to drive any speaker with ample power reserve. It sounds effortless, fluid and dynamic: the way the very best amplifiers should.
