Experience enhanced power and versatile digital integration with the new Musical Fidelity M6xi integrated amplifier.
A Fresh Take on a Classic Favorite
If you’ve ever been captivated by the rich analog warmth of Musical Fidelity’s “si” series, then the new Musical Fidelity M6xi integrated amplifier is about to become your next audio obsession. Building upon the proven circuit design of its award-winning predecessors, the M6xi brings a slew of modern connectivity options and system-friendly features that elevate its already stellar performance. This amplifier is not just an update; it’s a thoughtful refresh designed to blend classic sound quality with contemporary convenience.

Connectivity That Makes Life Easier
The M6xi tackles the ever-important “quality-of-life” upgrades head-on. Gone are the days of scrambling for adapters or settling for limited inputs. Musical Fidelity has equipped this powerhouse with:
- Optical, coaxial, and HDMI ARC inputs — perfect for seamlessly linking your TV, gaming console, or streaming device.
- A USB-C input, reflecting the modern standard for digital connectivity.
- An RS232 connector designed for custom integration setups—ideal for home automation enthusiasts who love fine-tuning their systems.
- A 5 V, 2 A USB-A power output to keep your external streamers powered without the fuss.
- A dedicated home-theater bypass input, allowing the M6xi to serve as a focused power amplifier in multichannel setups.
This versatile array of inputs means the M6xi integrated amplifier easily slips into just about any audio system, whether you’re a vinyl devotee, digital streamer, or cinephile craving immersive sound.
Power and Precision Reimagined
The M6xi isn’t just about smarter connectivity—it’s a beast under the hood. Boasting an impressive increase in power, it delivers:
- 230 watts into 8 ohms
- 390 watts into 4 ohms
This power upgrade surpasses the previous M6si model and is driven by an amplifier stage derived from Musical Fidelity’s acclaimed TITAN platform. One of the standout features is the low-distortion Darlington output stage, engineered to minimize crossover artifacts and residual distortion. For audiophiles who notice every subtle nuance, this means cleaner, more faithful sound reproduction.
Adding to the sonic purity is a meticulously optimized printed circuit board layout that reduces circuit imbalances. Meanwhile, fully analog power supplies during operation help limit the high-frequency noise and electromagnetic interference that often muddy audio signals.
Preamplifier Excellence
Every audiophile knows the preamplifier stage is where magic begins. The M6xi’s preamp is no exception, crafted with low noise and consistent performance across all volume levels. A Burr-Brown stepped attenuator ensures precise channel matching, providing balanced sound that stays true no matter the volume.
Additional fan-favorite features include:
- A pre-out for bi-amping or seamless integration with a subwoofer.
- A phono input compatible with both MM (Moving Magnet) and MC (Moving Coil) cartridges, perfect for vinyl enthusiasts who want to spin their favorite records with authentic depth.
Designed to Impress Inside and Out
The M6xi’s physical presence matches its sonic prowess. Enclosed in a rigid aluminum chassis, the front, side, and top panels are milled from extruded profiles, giving the amplifier a clean, durable look that screams quality. This all-metal enclosure also provides effective shielding against electromagnetic interference, ensuring your music stays pristine without unwanted noise sneaking in.
At $3,799, the M6xi integrated amplifier stands as a premium offering for those who demand both performance and cutting-edge features in one elegant package.
