Musical Fidelity M5xi Integrates Power & Flexibility

Following the recent news of Musical Fidelity’s M6xi, the company has done the inevitable and announced the upgraded M5xi.

The M5 series has always been the brand’s more accessible slice of high-end, an M6-lite, if you will. Now there’s a new one: the M5xi. And no, it’s not a sticker-and-a-firmware revamp—this one turns up with TITAN-inspired amplifier know-how, a phono stage that finally courts MC cartridges, and HDMI eARC for anyone who wants proper stereo sound on movie night without starting a domestic negotiation.

Musical Fidelity reckons the M5xi is a proper step-up from the outgoing M5si, with the preamp, power amp, digital board and phono stage all getting fresh attention. The headline is a revised circuit approach that pulls the M5xi closer to the firm’s brawnier TITAN-style thinking (also seen in the aforementioned M6 family), but in an integrated amp that won’t demand you clear a whole rack—or your bank account.

Musical Fidelity has stuck with the ‘two monos in one box’ idea and says the M5xi is essentially a preamp plus two independent mono power amps sharing the same chassis. Translation: left and right are kept more separate than in a typical integrated, which can help stereo imaging stay tidy when the mix turns into a wall of sound.

The crowd-pleaser here is HDMI eARC. If you’ve ever tried to sell the idea of ‘proper stereo’ to someone who just wants Netflix to work, eARC is your friend: one HDMI cable from the TV, and the M5xi handles amplification for your left/right speakers while keeping it all hi-fi.

Not stopping at HDMI, there are optical and coaxial digital inputs, plus a USB-C input good for up to 24-bit/192kHz playback. Old-school sources are covered too: four line-level RCA inputs, and a home theatre bypass.

Streamer fans also get an isolated 5V/2A USB-A power output, intended to feed a USB streamer from something cleaner than the average wall-wart. Add RS232 for custom-install control, pre-outs for bi-amping or a sub, and a fixed line out for, say, a dedicated headphone amp, and the M5xi starts looking like a system hub rather than “just” an integrated.

The phono stage isn’t a token add-on, either. Musical Fidelity says the M5xi’s phono section is completely new versus the M5si, with improved shielding and a revised layout aimed at dropping noise and distortion. Best of all, it now supports both MM (moving-magnet) and MC (moving-coil) cartridges.

Volume is controlled by a Burr-Brown stepped attenuator. This is a precision, step-by-step volume control. It keeps left/right levels better matched than a typical ‘twiddly’ pot. The result? More stable centre images and less “why did the soundstage just lean left?” at low volumes.

Under the lid, Musical Fidelity’s focus is the usual holy trinity: lower distortion, lower noise, and more current on tap when your speakers get demanding. The company highlights a low-distortion Darlington-style output stage (a transistor pairing often used for high-current delivery) and a revised board layout to reduce imbalances that would otherwise require corrective feedback.

The M5xi is rated at 160W per channel into 8 ohms, rising to 240W into 4 ohms. In other words, it should have the headroom to keep its cool with most real-world loudspeakers—even those that like to dip in impedance just when the chorus hits.

Meanwhile, the digital and HDMI boards are kept separate and fed by their own linear supplies, while the transformer and power-supply board sit inside a metal enclosure to help reduce electromagnetic interference—particularly handy when you’ve got a high-gain phono stage in the same box.

Build-wise, the M5xi’s all-metal case is designed to keep interference at bay, plus a chunky aluminium front panel.

There’s even a refreshed remote, with standby and mute control—small stuff, but it’s the sort of thing that stops you doing the sofa-to-rack shuffle when you’re already three tracks deep.

Pricing for the Musical Fidelity M5xi is A$4,500 | £2,099 | €2,290 | US$2,690, with pricing for other markets awaiting confirmation.
