M6SI500 – Integrated Amplifier

The M6si500 is a integrated amplifier that can easily drive any pair of speakers, without distortion or strain.

The M6si500 is a very high performance, high powered super integrated amplifier. Twenty-five years ago, the Musical Fidelity A1000 started the complete super integrated amplifier genre. Over the last two and half decades we have continued to refine our original concept.

The M6si500 offers a comfortable 500 watts per channel, incredible load driving ability, outstanding technical performance and solidly engineered build quality. This remarkable integrated amp will drive any loudspeaker virtually perfectly and to its maximum potential.

It has five inputs: 4 x line and 1 x balanced XLR.

Listening to the M6si500 is a sensuous experience. It produces an effortless, silky sound with huge dynamics. The sound stage is broad and deep. Even if you arent in the market for an amplifier at this level, you should listen to it to better understand why it is generating such enthusiasm.

M3si In Brief

• 500WPC

• Fantastic technical performance

• Amazing load driving ability, will drive any loudspeaker with ease

• Five inputs – Balanced XLR, CD, Tuner, Aux / HT, Tape

• Preamp and fixed line outputs

• Home Theatre bypass

• Internally it is a separate preamp with two independent monobloc power amps; effectively a separates system in a box

• Excellent, he-man build quality

The M6si500 offers prodigious power 500 Watts per channel into 8ohms but there’s so much more to it than muscle.

The M6si500 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 M6si500 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 M6si500.

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 M6si500 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.

REVIEW & AWARDS

Musical Fidelity M6 500i Integrated Amplifier Review –Read More

“As I hope, the rest of the review has shown, the reality is rather different. As people often lament, the idea of true transparency in two channel is often rarer than many would like. This is a 30kg, aesthetically imposing riposte to that complaint. The operating envelope of the M6 500i is so enormous that for any (thats right, Im using an absolute) domestic situation, what you will get is exactly what is sent. This means that partnered with similarly capable components such as the Chord Qutest and Q Acoustics Concept 500, youd have a system that would be utterly accurate – a genuine window on the music – for dramatically less than such a system would normally cost you. The M6 500i is one of the all-time great integrated amplifiers and the fact it is back at a lower price than it has ever been before means that this time, it can earn a Highly Recommended accolade.” – Ed Selley

“Musical Fidelitys M6 500i is a gentleman thug of an integrated amplifier blessed with equal helpings of brawn and delicacy. These seemingly opposing strengths will attract different types of listeners, but this model is worthy of universal respect. It was a pleasure to make the acquaintance of this latest and greatest in MFs line of British specials. I will be sad to see it depart.” –Hans Wetzel

Musical Fidelity M6 500i Integrated Amplifier Review – Read More

“A 500wpc amp in such a tidy package is music to this audiophiles ears! I love big power amps; the cleaner and more powerful the better! But, as aforesaid, the simplicity of the dual Pathos integrateds was beguiling. There is a direct payoff sonically relative to system costs when one simply skips the preamp and extra set of cables for a fine integrated. The problem is that often the integrated with high end sensibility is unable to fulfill the promise of a big gun amp, which can drive nearly any speaker on the market effortlessly. The M6 500i resolves that issue.” – Doug Schroeder

Hi-Fi Choice 06/13

“This will be the ultimate amp for many audiophiles!”

Hi Fi World 09/11

“Excellent sound, rock-like build and attractive styling”

wstereo 05/22

“The amplifier focuses on the speed and precision of the presentation, gives sounds resolutely and control them without mercy. This is due to the really impressive power. It gives a very good insight into the recording.” – Maciej Stempurski
