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.

Great scent, hydrating, not greasy or sticky.
Scent: Mellow Coconut, Size: 13.2 Fl Oz (Pack of 1)
This Karl&Hans Moisturizing Body Lotion is a good value at approx $23 on Amazon right now. This is a large 390 ml bottle of lotion. Thankfully it comes with a pump that worked well and made it convenient to use. I especially used it a lot after washing my hands. It's a lightweight lotion with a delicious coconut, musky scent. I was immediately interested in this because of the PDRN and ceramide complex. My skin is always dry and needs support, and this lotion left it soft, soothed, and hydrated. This absorbed quickly, and I didn't notice any lingering issues of feeling greasy or sticky.

Buy it for the scent, keep using it for the benefits...
Scent: Mellow Coconut, Size: 13.2 Fl Oz (Pack of 1), Scent: Mellow Coconut, Size: 13.2 Fl Oz (Pack of 1)
During the pandemic, I became a bit of a skincare fanatic. I didn't have much to do otherwise, and so I began collecting various creams, lotions, serums, and other products that claimed they would help regain what I had lost or would help prevent what was coming. I stuck with a few things after I got back to work but honestly did not have the time to sit down and apply this to that and that to his. In all seriousness, I really did enjoy it all. I found a few favorites, a few holy grails, and I've continued to use those products. I recently started looking for something new and I discovered a new ingredient. Well, I didn't discover it, I just happened upon it as a main ingredient in many skincare products. At first, silly me thought it was a new brand. Then I started seeing it pop up in a lot of product description pages. Polydeoxyribonucleotide or better known as PDRN. I did a little research on the internet as one does and found that the PDRN is quite popular nowadays in the world of skincare because of its regenerative and healing properties. I am all here for regenerative and healing properties in my skincare products. I look forward to learning more about this new (to me) ingredient. I came across this bottle 13.2-ounce bottle of Karl & Hans Moisturizing Body Lotion not too long ago and it promised deep hydration with its coconut-derived extracts and it, too, had some PDRN in it, RICERA PDRN plus ceramide complex, to strengthen the skin barrier. Now, I've only been using it for about a month, when I'm home. With it's tall pump bottle containing 13.2 ounces of product, it's a bit too big to be sticking it in my purse. I do, however, keep it in my bathroom and use it as my body lotion after my showers. First of all, the smell is just incredible. I just used it to inspire this review. A good pump of this lotion was more than enough to moisturize my hands and my arms. What surprised me about this lotion was how fast it absorbs into my skin. There is no tacky or greasy feeling after application, the only evidence I've just used a lotion is the dry skin on my hands is not as noticeable due to the moisturizing properties of this lotion and the lovely soft scent of coconut wafting about the room. My skin feels soft and the dry skin isn't as evident. I haven't been using this product enough to say that it can do what it claims, but I can say that I enjoy and like this lotion very much and will continue to use it. at $1.74 an ounce, it's definitely an affordable skincare option to continue to use all over the body, after every shower and on my hands after every handwash. I think it would be a great gift to each of the team of ladies I work with. I've often received remarks that I smell so good from them, and I just smile because it's not a fancy, expensive perfume I imagine they think it is. It's just a great lotion that I got from Amazon. If, over time, I see the overall appearance of my skin appear healthier, than I will consider that a double win. I definitely recommend this moisturizing lotion. I am happy with using it and I think you will be, too. Gift it to yourself or to your friends. The scent as lovely as it is, could also be used by the men in the house, too. I might start keeping my bottle by the kitchen sink so my husband could enjoy it as I do.

Love the scent! Paraben free and really hydrating
Scent: Mellow Coconut, Size: 13.2 Fl Oz (Pack of 1), Scent: Mellow Coconut, Size: 13.2 Fl Oz (Pack of 1)
I've never used any Karl&Hans product before, but I'm really impressed with what they've done here. Contrary to the very European name, this lotion is made in Korea. The Mellow Coconut fragrance isn't subtle, but it's relaxing. It's blatantly coconut right off the bat, but when it settles in, there's a lingering fruity vanilla scent. It'll stay wafting around you for a good amount of time after application. The lotion is pretty rich and thick in consistency. It's not quite a cream, but it's thick enough that it doesn't run much, or at all, when you plop some on a vertical surface. That might just be because it's cold where I am, though, so it might be more runny in hotter climates. The thickness betrays how easily it rubs in. It's super quick to absorb and hydrates well without feeling heavy. My skin feels moisturized but not sticky or greasy. PDRN seems to be the hot buzz ingredients of the times right now. I'm not fully educated in the science behind it, but this lotion is really turning me into a believer of whatever skincare magic it's supposed to work. According to Skin Safe, it's also free of parabens, nickel, lanolin, and a bunch of other top common allergy causing preservatives. At $23 for 13.2 fl oz/390 ml, this is definitely steeper in price than your average body lotion, but it works some serious magic in the moisturizing department. It's been a good while since my skin felt so satisfyingly supple. I'd prefer if the scent weren't quite as strong, I can't deny it smells good.

Side by side comparison ......
Scent: Fresh Mint, Size: 13.2 Fl Oz (Pack of 1)
Like everyone else shopping around for lotion, I want one that, most importantly, works. I'm so very tired of lotions that feel like I'm applying colored water to hands so my go to lotion has become Gold Bond as it's a genuinely thick, somewhat long lasting lotion with minimal scent at a decent (ish) price point. I am however, always looking to find something even better so I thought I'd give this stuff a try. This is just an estimation, but I feel it is about 20% less viscous than the Gold Bond Healing lotion however, in a side by side test where I applied the back of one hand with the GB and the back of the other with this K&H brand, after one hour the K&H feels every bit as supple but just a tad more velvety if you will. Although I prefer a non scented lotion, after an hour, the K&H scent has indeed lighted up a bit but smells better than the GB. The GB seems to almost have an underlying petroleum type odor - not offensive really but just that the K&H smells better to me is all. The Gold Bond does get the favoring nod in the price dept though as it's very close to 50% less expensive than this Karl & Hans. If all things were equal (and that includes the price), I'd pick the K&H over the GB however with price point always being of concern for me personally, I don't think the attributes of the K&H beat out the overall value of the GB.
