Description

Musical Fidelity The M5xi is the profound evolution of the celebrated M5si and brings the circuit topology derived from the flagship into its price range. TITAN, already adopted in the M6xi and now re-proposed with lower output power but with the same construction philosophy. The result is a hi-fi integrated amplifier which delivers 2x160W on 8 ohms e 2x240W on 4 ohms, internally structured as two mono power amplifiers flanked by a common preamplifier, with transformer and power supply stage enclosed in a shielding metal casing which drastically reduces electrical interference.romagnetic.

The Burr-Brown stepped volume control replaces traditional potentiometers and ensures a perfectly balanced stereo image and consistent tonal accuracy at all listening levels, while the all-analog preamp section preserves microdetails with extremely low total harmonic distortion. The MM/MC phono stage is completely new compared to the M5si – which only had a MM input – and offers optimized shielding, up to 60 dB of gain for moving coil cartridges and an accurate RIAA curve, ideal for enhancing medium-to-high level turntables.

On the digital front, the boards are physically separated on dedicated PCBs with independent linear power supplies. The coaxial, optical, and USB-C inputs accept signals up to 24-bit/192 kHz , while the HDMI eARC input allows you to integrate with a TV or home theater system by taking advantage of the amplifier's powerful analog stages. A distinctive feature is the isolated and ultra-linear 5V/2A USB-A power output , with a dedicated winding on the main transformer: by directly powering external streamers such as USB-bridges, it effectively acts as an upgrade to their power stage, with audible benefits on the sound quality of high-resolution audio streaming.

What's the best integrated amplifier for vinyl, streaming, and home theater use in the same system? The M5xi delivers with comprehensive connectivity: 4 RCA line inputs, 2x RCA input, 1 ... HT bypass for integration with multi-channel processors, variable pre-amp output for bi-amp configurations or for active subwoofers, fixed pre-output for headphone amplifiers, as well as RS232 connector, trigger in/out and 4mm banana speaker terminals. The front panel is made from a solid aluminum extrusion, with a chassis that acts as a Faraday cage to protect the internal circuitry. The equipment is completed by a new universal remote control for the entire M line of Musical Fidelity.

The M5xi is aimed at those looking for a integrated stereo amplifier capable of authoritatively driving even demanding speakers, of managing the vinyl with a quality phono stage and tackle the hi-fi streaming modern without requiring additional components. A proposal that brings the high-end philosophy of Musical Fidelity at a level of access that is difficult to match in the category.

Integrated, Pre-Amplifier, or Receiver: A Guide to Choosing

When building a Hi-Fi system, choosing the right amplifier is one of the most important—and often confusing—steps. Integrated amplifier, preamplifier and power amplifier pair, receiver: three different philosophies, three ways of understanding sound and experience…

What is an integrated amplifier and why is it the point

The integrated amplifier is the most common solution in home Hi-Fi, and for good reason. It combines two essential functions in a single chassis: the preamplifier, which manages the sources, adjusts the volume, and shapes the audio signal, and the power amplifier, which amplifies the signal to drive the speakers. It's the natural choice for those who want a complete, efficient, and ready-to-use system without complications.
