Musical Fidelity M6xi Integrated Amplifier

Description

About the Musical Fidelity M6xi Integrated Amplifier

The Musical Fidelity M6xi Integrated Amplifier uses two independent monobloc power amplifiers with a separate preamp stage in one chassis. It also includes a built-in MM/MC phono stage, USB-C 24-bit/192kHz input, HDMI eARC, optical, coaxial, balanced XLR, four RCA inputs, pre-out, fixed line out, RS232, and a 5V/2A USB-A power output for streamers.

At Rapallo, the Musical Fidelity M6xi is exactly the sort of integrated amplifier we like for customers who want serious drive, but do not want a rack full of separates.

The power output is the first thing you notice on paper. However, the real appeal is control. The M6xi has the current and headroom needed for more demanding speakers. As a result, it suits larger rooms, floorstanding speakers, and customers who enjoy dynamic listening.

We also like how practical it is. The HDMI eARC input makes TV sound simple. The MM/MC phono stage supports both moving-magnet and moving-coil cartridges. Plus, the USB-C, optical, and coaxial inputs cover digital sources without needing a separate DAC for many systems.

The design still stays true to Musical Fidelity’s core strengths. It is not a streaming amplifier. Instead, it is a powerful analogue amplifier with useful digital access built in. Therefore, it is a great match for customers who want to choose their own streamer, turntable, DAC source, or TV connection.

For NZ customers building a premium stereo system, the M6xi is a strong amplifier choice. It pairs especially well with speakers that benefit from current, grip, and scale.

What the Experts Say

• Gear Patrol covered the M6xi launch and described it as an upgraded successor to the M6si, combining a power amplifier, preamplifier, phono stage, DAC, and broad connection set in one all-metal chassis.
• eCoustics reported that the M6xi builds on the proven analogue circuit design of Musical Fidelity’s award-winning “si” series while adding expanded digital inputs and stronger system integration.

 

Frequently Asked Questions

1. What is the Musical Fidelity M6xi?
   The Musical Fidelity M6xi is a high-power integrated amplifier with a built-in preamp, dual-mono power amplifier design, MM/MC phono stage, DAC inputs, HDMI eARC, and analogue connectivity.
2. How powerful is the Musical Fidelity M6xi?
   Musical Fidelity rates the M6xi at 220W per channel into 8 ohms and 320W into 4 ohms at 1kHz. It is also rated at 210W per channel into 8 ohms and 300W into 4 ohms from 20Hz to 20kHz at lower distortion.
3. Does the M6xi have a built-in DAC?
   Yes, it includes digital inputs. These include USB-C, optical, coaxial, and HDMI eARC. The USB-C input supports up to 24-bit/192kHz audio.
4. Does the M6xi have a phono stage?
   Yes, it includes a built-in MM and MC phono stage. This means you can connect many moving-magnet and moving-coil turntables directly.
5. Can I connect the Musical Fidelity M6xi to my TV?
   Yes, the M6xi includes HDMI eARC. This allows compatible TVs to send audio to the amplifier through a single HDMI connection.
6. Does the M6xi have Bluetooth or built-in streaming?
   No, the M6xi does not include Bluetooth or built-in streaming. However, it includes a 5V/2A USB-A power output that can power many external streamers.
7. Can I use the M6xi in a home theatre system?
   Yes, it includes a Home Theatre bypass input. This lets the amplifier power your front left and right speakers while an AV receiver or processor controls volume for surround sound.
8. What speakers pair well with the M6xi?
   The M6xi pairs well with demanding bookshelf and floorstanding speakers. Good matches include Focal Aria Evo X, Paradigm, Triangle, ELAC, and Klipsch Heritage models.
9. Who is the Musical Fidelity M6xi best suited to?
   It is best for customers who want a powerful premium integrated amplifier for music, vinyl, digital sources, TV sound, and demanding speakers, without moving into separate preamp and power amp components.

 

Key Features

Serious High-Power Performance

The M6xi delivers 220W per channel into 8 ohms and 320W into 4 ohms at 1kHz. It is also rated at 210W per channel into 8 ohms and 300W into 4 ohms from 20Hz to 20kHz at 0.09% THD. Therefore, it has the power reserves needed for demanding loudspeakers and larger rooms.

Dual-Mono Amplifier Architecture

Musical Fidelity configures the M6xi as two independent monobloc power amplifiers with a separate preamp stage in the same case. This helps improve channel separation, stability, and authority.

Circuitry Derived from TITAN

The amplifier uses technology derived from Musical Fidelity’s TITAN power amplifier. It includes a low-distortion Darlington output stage designed to avoid crossover artefacts while preserving musical detail.

Built-In MM/MC Phono Stage

The M6xi includes an upgraded MM and MC phono stage with improved PCB layout, shielding, and isolation. As a result, vinyl listeners can connect a quality turntable directly without needing an external phono preamp straight away.

HDMI eARC for TV Audio

The HDMI eARC input makes it easy to connect a compatible TV. Therefore, the M6xi can work as the heart of a premium stereo TV and music system, especially when paired with capable floorstanding speakers.

High-Resolution Digital Inputs

The M6xi includes USB-C, optical, and coaxial digital inputs. The USB-C input supports up to 24-bit/192kHz audio, making it suitable for computers, streamers, and compatible digital sources.

Balanced XLR Input

A balanced XLR input is included for compatible DACs, streamers, and source components. This gives the amplifier extra flexibility in premium hi-fi systems.

Home Theatre Bypass

The HT input bypasses the preamp stage. This lets the M6xi act as a high-performance front left/right amplifier inside a multichannel home theatre system.

USB-A Power Output for Streamers

A 5V/2A USB-A power output can power modern external streamers. Musical Fidelity states this output has its own transformer winding and linear power supply stage, helping simplify setup and reduce power supply clutter.

Heavy Aluminium Chassis

The front and side panels are milled from extruded aluminium profiles. Musical Fidelity also describes the chassis as helping protect the internal circuits from electromagnetic interference.
