The Musical Fidelity M5xi is an integrated amplifier that combines the preamp and power amp in one case. It is a fully discrete dual-mono design, with two separate power amp channels beside their own preamp stage. The output stage traces back to the TITAN, Musical Fidelity's kilowatt power amplifier, and uses Darlington transistors for stability.
It delivers 160 watts per channel into 8 ohms and 240 watts into 4 ohms, with peaks of 190 and 320 watts. A built-in phono stage switches between moving magnet and moving coil and has extra shielding, so a turntable connects directly to the back panel. HDMI eARC lets a TV send its sound over one cable, and coaxial, optical and USB-C inputs handle other digital sources at up to 24-bit and 192kHz.
The transformer and power supply sit in their own shielded metal box. The front panel is milled from solid aluminum. A powered USB-A port supplies 5 volts at 2 amps, enough to run a small network streamer. The M5xi is a wired amplifier with no Bluetooth.
