Description

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 aren’t in the market for an amplifier at this level, you should listen to it to better understand why it is generating such enthusiasm.

M6si500 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.

Why Choose Musical Fidelity

Musical Fidelity is a British Hi-Fi manufacturer with a long-standing reputation for producing powerful, musically engaging amplifiers and source components designed around one simple philosophy — deliver big, effortless sound without unnecessary complication. Since the company’s beginnings in the 1980s, Musical Fidelity has developed a loyal following through products that combine strong engineering, substantial power delivery, and a highly enjoyable analogue-inspired presentation.

What makes Musical Fidelity particularly distinctive is the company’s focus on real-world amplifier performance and current delivery. Rather than chasing minimalist specifications or ultra-clinical presentation, Musical Fidelity products are engineered to sound expansive, confident, and highly musical across a broad range of loudspeakers and listening environments.

At HeyNow Hi-Fi, Musical Fidelity products consistently appeal to customers seeking amplifiers that combine authority, warmth, and strong system flexibility while still maintaining genuine high-end performance credentials. There is a sense of scale and ease to the sound that works beautifully with both digital and analogue systems.

Signature Design and Sound

Manufactured around substantial analogue amplifier platforms, Musical Fidelity products are engineered with oversized power supplies, high-current output stages, and strong emphasis on maintaining musical dynamics and tonal body even at lower listening levels.

The current B Series and M Series products in particular have attracted extremely strong international reviews for their ability to combine modern connectivity with the company’s traditional amplifier strengths. One especially useful feature within the newer range is the inclusion of HDMI eARC connectivity, allowing customers to integrate television audio directly into high-quality stereo systems without additional switching hardware or unnecessary complexity. For many customers, this creates a far more engaging alternative to conventional soundbars while maintaining proper Hi-Fi performance for music listening.

Musical Fidelity also continues to place strong emphasis on analogue integration, with many products incorporating high-quality DAC stages, moving magnet and moving coil phono preamplifiers, balanced connectivity, and substantial speaker-driving capability within highly versatile integrated amplifier platforms.

Sonically, Musical Fidelity products are known for their scale, warmth, and effortless dynamic presentation. The sound feels full-bodied and spacious, with strong bass authority, smooth tonal balance, and impressive long-term listenability. Rather than sounding overly sharp or analytical, the presentation remains inviting and highly musical while still preserving excellent detail retrieval and control.

Musical Fidelity Product Range

The Musical Fidelity range available through HeyNow Hi-Fi focuses primarily on the highly regarded B Series and M Series amplifiers, DACs, integrated amplifiers, and digital playback components designed for customers seeking strong amplifier performance together with modern system flexibility.

Products within the range combine substantial current delivery, refined analogue presentation, extensive connectivity, and practical integration features including HDMI eARC support, making them particularly attractive for modern stereo systems that integrate both music and television playback.

At HeyNow Hi-Fi, Geoff and his experienced system setup team provide assistance with speaker matching, television integration, analogue setup, streamer configuration, and complete system optimisation to ensure Musical Fidelity products perform at their full potential within each customer’s listening environment.
