The M5xi is a high-end amplifier with incredible realism and emotional involvement.

From M5si to M5xi

Building on the outstanding success of its predecessor, the M5si, the M5xi is a major reinvention of the M5 formula. The preamp, poweramp, digital and phono sections are completely new and now much closer to our legendary TITAN power amp topology. In fact, the M5xi now commands the same topology as previously used in the M6si, including all the improvements for the newly released M6xi update, just tuned for less power output. This makes the TITAN formula accessible at a new price-point as Musical Fidelity pushes to make true high-end amplifiers as affordable as never before.

Modern systems demand modern connectivity. The M5xi now features HDMI eARC, allowing effortless integration with TVs and home theatre systems while delivering true high-end stereo performance. Alongside this, new coaxial and optical digital inputs expand connectivity for a wide range of digital sources, complementing the already established high-resolution USB input.

A completely new feature is the high-quality isolated USB power output. Designed as a dedicated, ultra-clean power supply, it allows you to power modern USB streamers directly from the amplifier. The result is simple system integration and a noticeable upgrade in performance for your favourite streaming source.

For professional installations and advanced system control, the M5xi now includes RS232 integration, making it ideal for custom installations and sophisticated home audio systems.

Fully Discrete Power Amplifier - Son of TITAN

The biggest change, when compared to the old M5si predecessor, is that the M5xi now uses a completely new amplifier topology. It is now even closer to our legendary TITAN power amp design. The same topology that has been used in the M6si previously, and has now received a whole range of improvements in the M6xi, is now found at the core of the M5xi as well, only tuned for less output power.

The M5xi is configured as 2 independent monobloc power amps with a separate pre amp. It is, in fact, a pre amp with 2 monobloc power amps that just happen to share the same casework. It features technology trickled down from our legendary 1kW TITAN power amp.

Internally, refinements push performance even further. The main transformer and power supply PCB are now encapsulated within a metal enclosure, dramatically reducing electromagnetic interference inside the chassis. This improvement benefits every circuit in the amplifier, but especially the newly refined phono stage.

The upgraded MM/MC phono section features improved shielding and circuit optimization, delivering lower noise, lower distortion, and greater vinyl transparency than ever before.

Even the powerhouse amplifier stage has been slightly enhanced. With improved components and increased output capability, the M5xi delivers even greater authority and control over demanding loudspeakers, than its predecessor, while preserving the effortless musicality that defines the Musical Fidelity sound.

The result is an amplifier that combines classic Musical Fidelity high-end amplifier design with modern versatility. The M5xi delivers true high-end performance in the proud Musical Fidelity tradition and makes it more accessible than anything else in its class.

Technical Talk

The new Musical Fidelity M5xi represents the next evolution of high-end integrated amplification with advanced engineering drawn directly from our flagship designs. Built to deliver uncompromising sonic performance, the M5xi merges sophisticated circuitry and meticulous PCB layout with modern connectivity in a design that sets new standards for its class.

The M5xi is tuned for less power output than the M6xi, making it a better candidate for smaller rooms or shorter listening distances. However, you will struggle to find loudspeakers that the M5xi cannot properly and fully drive as the M5xi now commands the same power amplifier topology as the M6si and M6xi.

Power Amplifier

Configured as 2 independent monobloc power amps with a separate pre amp, at its core lies amplifier technology derived from Musical Fidelity’s prestigious TITAN power amplifier. This heritage ensures exceptional stability, authority, and musical control. The M5xi employs a low-distortion Darlington output stage arranged in the classic Musical Fidelity configuration. This design eliminates crossover artefacts while maintaining extremely low residual distortion, preserving musical detail and tonal accuracy across the entire frequency range.

Great attention has been given to the internal PCB layout. The carefully optimised board design minimises circuit imbalances that would otherwise require corrective feedback, allowing the amplifier to operate more naturally and transparently. During operation, all power supplies remain purely analogue, reducing high-frequency noise and minimising EMC-related interference. The result is a cleaner signal path and improved overall sonic purity.

Power delivery is another defining characteristic of the M5xi. With 160 watts per channel into 8 ohms and 240 watts into 4 ohms, the amplifier possesses immense current capability and extraordinary headroom. These extreme power reserves ensure accurate peak power delivery and a wide dynamic range, allowing the M5xi to drive demanding loudspeakers with complete authority while remaining composed during low-impedance dips.

Preamplifier

At the heart of the M5xi lies a meticulously engineered fully analogue preamplifier stage designed for absolute signal integrity. The preamplifier features a low-noise circuit design that maintains exceptional signal purity across the entire dynamic range. Whether at quiet listening levels or full-scale output, the M5xi preserves microdetail and harmonic accuracy with remarkably low total harmonic distortion. The result is effortless clarity, stable imaging, and uncompromised musical realism.

Volume control is handled by a high-quality Burr-Brown stepped attenuator, offering significantly more precise channel matching than conventional potentiometer-based designs. The advantage is immediately audible: perfectly balanced stereo imaging, stable soundstage placement, and consistent tonal accuracy across all listening levels.

The M5xi embodies Musical Fidelity’s philosophy: combining uncompromising engineering with real-world usability making true high-end amplifier design as affordable as possible. The result is an integrated amplifier that delivers immense power, exceptional control, and remarkable transparency. Designed for music lovers who demand nothing less than true high-end performance.

Phono Stage

Vinyl playback receives equal attention with the new MM and MC phono stage. Compared to the M5si stage, this is a completely new development. Improved circuit design and layout, combined with enhanced isolation and shielding, significantly reduce noise and distortion. The result is a phono input capable of revealing the full warmth, depth, and dynamic nuance of high-quality vinyl recordings. Vinyl enthusiasts will greatly welcome the addition of a MC stage, as the old M5si only featured a MM phono stage.

The position of the transformer and power supply PCB have been carefully tuned, rearranged and encapsulated in a metal enclosure to decrease electromagnetical interference towards all parts of the amplifier. The phono stage circuitry benefits greatly as it works with high amplification factors up to 1.000. It is absolutely crucial to shield high gain amplifier stages from any and all external interference.

Separate digital boards

Digital and analogue hardware needs to be carefully separated from each other. Even the smallest amount of RF interference is known to cause trouble for analogue amplifier stages. Therefore, the digital and ARC boards are physically separated on their own PCBs and have their own linear power supply.

The digital coaxial, optical and USB-C inputs accept high-resolution sample rates up to 24bit and 192kHz and the HDMI eARC input allows your home theatre to be brought to life and properly invigorated by the powerful M5xi analogue amp stages.

Inputs & Connectivity

The M5xi features 4x RCA inputs line inputs. The built in MM & MC phono stage has received a significant upgrade compared to the M5si; delightful news for any phono stage enthusiast as in addition to the technical improvements, it now supports MC cartridges too.

For system flexibility, the M5xi includes a home theatre bypass input. The HT input bypasses the preamplifier stage entirely, allowing seamless integration with home theatre processors and enabling the M5xi to perform as a high-performance stereo power amplifier for your left and right speakers within a multichannel system.

Connectivity has also been expanded to meet the needs of modern audio systems. New optical, coaxial, and HDMI eARC inputs provide versatile digital connectivity, while a new USB-C input supports high-resolution audio up to 24-bit/192 kHz. For custom installation and system control, the M6xi now features an RS232 interface.

In addition, a new 5V/2A USB-A power output allows the amplifier to conveniently power modern external streamers, simplifying system setup and reducing the need for additional power supplies. This output has its own separate transformer winding and linear power supply stage, effectively also doubling as a power supply upgrade for your favourite streamer.

Digital integration is equally refined. The USB input features a carefully optimized digital circuitry layout, specifically designed to minimize high-frequency interference within the M5xi. This meticulous engineering protects the sensitive analogue signal path, ensuring the digital section never compromises the amplifier’s sonic purity.

For system expansion, the M6xi includes dedicated pre-out connections. The variable Pre-Out allows seamless integration with external power amplifiers for bi-amping configurations. It also provides a convenient connection for active subwoofers, enabling greater flexibility in building high-performance systems. The fixed Line Out connection is best suited to connect your favourite headphone amplifier.

Heroic Build Quality

The M5xi‘s front panel is milled from a massive extruded aluminium profile.The mechanical build quality shows excellent immunity against the effects of vibration from the environment. The same can be said about electro magnetic immunity. The massive metal case acts as a Faraday cage. It protects the internals against outer electromagnetic fields, and in the same way, the rest of your HiFi gear against electromagnetic fields generated by the M5xi.

New Remote Control

The M5xi has received a significant remote control update. The redesigned remote features an elegant, lightweight construction that sits naturally and comfortably in the hand, making everyday operation effortless. Thoughtfully colour-coded in the distinctive Musical Fidelity brand colours, the remote is designed for seamless universal compatibility across Musical Fidelity’s M-line components, including amplifiers, CD players, and DACs. One beautifully designed controller brings effortless command of your entire system.

Nice looking. Not very sturdy. Easy to install.
Size: 40x7 2Pcs, Color: White, Size: 40x7 2Pcs, Color: White
Update: The shelf slopes at about a 45° angle when you put anything more than about a pound on the outside edge of it. Perfectly fine up against the wall. Just seems like the braces inside aren't long enough to really give the stability needed. Bracket is nice and tight against the wall. Had to add braces underneath to hold a small plant, a photo and a small container. Wa sloping more and more each week The shelves look great and we're pretty easy to install. They have a single bracket that is very easy to mount to the wall and get nice and level.. The downside is that the bracket isn't long enough to go between studs. This seems like a pretty simple oversight. I mean why wouldn't you make it long enough to go stud to stud? Secondly and maybe more fatally the bars that go inside the shelf to support them coming out from the wall are significantly shorter than the depth of the shelf. Unfortunately this means the shelf is only supported the first few inches coming out from the wall so there is the potential for a slight lean forward.. The anchors they send are trash. Cheap soft plastic that just tears and bends with a screwdriver. I would suggest spending $2 and grabbing your own anchors from Ace or home Depot. The shelves are essentially made of a high grade cardboard kind of wood. They are not going to support much weight or last for years and years however there incredibly affordable and look nice and easy to install. Long as your expectations are right you'll be happy.

Worth it if you're a figure/doll collector!
Color: A. Black Board & Black Brackets, Number Of Shelves: 4, Size: 16-inch, Color: A. Black Board & Black Brackets, Number Of Shelves: 4, Size: 16-inch
I ordered these shelves to display my figures and dolls, and I love the way they look! I ordered 2 sets of the 4 pack in black with black hardware. After looking at reviews, I took the jump and bought them and don't regret it! TL;DR: Listing is accurate, don't use the paper measurement thingy, quality is what you'd expect for the price, doesn't come pre-drilled, easy enough to put together, over all worth it if you're looking for smaller, decent quality, decent price shelves especially if you display figures or dolls. 1. Listing: They are accurate to the measurements! They're only 5.5 inches deep, so there isn't much (if at all) any room for layering. They do feel small, but the listing is accurate!! Mine are paired next to each other to create a "longer" shelf. DO NOT use the paper measurement thingy. Another review mentioned it was un-even, and after holding it to mine, yeah, it was off. I'd highly recommend a stud finder, small leveler, and a white gel pen or marker to mark where to drill if you do. 2. Assembling & Mounting: The shelves didn't come with pre-drilled holes for the mounting options because it was easy enough to screw into. I will warn you that the small screws only came with a singular extra, so be careful about losing them in case it's the same for you... I'd highly recommend doing this on a FLAT surface. I stood the shelves on the side that would be flat against the wall and set the brackets against it. I put one screw in on each side (both brackets have 1 screw to hold them where I want) then I laid it on its top and tightened and added the other screw. I may have done more work than needed, but none of mine are leaning forward or backward super far. I used the "load bearing" mount simply because I like the look but if you intend to put books, I would do the "no drop" design and possibly get some other L brackets for more support since books can get heavy. PLAN WHERE YOU WANT THE BRACKETS if you intend on doing the "load bearing" design or adding any more brackets. 4. Quality: I kind of expected the wood to be a bit thicker/more sturdy feeling, but upon realizing they didn't come pre-drilled, it made more sense. THEY CHIP AND SCRATCH EASILY. If you're like me and don't really care as long as you cant see/don't notice it, then this isn't any concern but they may come damaged cause some of our mail couriers aren't the best. If you stick them in the corner like I did, please be careful about it slipping! I accidentally dropped the second one from a 21-inch TV stand after adding brackets, and the corner chipped (yes, I measured). The hardware is standard screw quality, and the brackets could be better. After reading the broken bracket reviews plus the price, I honestly wasn't expecting much, but they aren't too bad! You can always replace them with another one you like! 5. Overall: I'd say these are worth the price and I see why "customers usually keep this item"! They were easy enough to mount, even if you aren't the handiest man out there. I'd definitely recommend these if you're looking to display anime figures or dolls like I do! They're nice for adding vertical space without sticking out of the wall too much! Definitely good for smaller spaces! I'm very happy with this product and will more than likely return to this listing if I want some decent and affordable shelving! Thank you for reading my review, Im usually hesitant to buy online so I hope it helps you decide if you wanna buy these shelves as well! (Also, in case anyone is wondering the layout, the longest shelf will be 1, the middle length will be 2, the shortest length will be 3. It's the last image of the review!)
