The HEMI nameplate has been practically synonymous with raw Chrysler horsepower since the 1960s, though the engine configuration itself dates back much farther. Named for its hemispherical combustion chamber, these engines feature inherently unique geometries: Valvetrains, pistons, and other components are all different to other layouts by design — combustion chambers are optimized for different purposes based on what’s expected of the engine.
In the HEMI’s case, a hemispherical combustion chamber generates higher chamber pressures versus a a more typical pentroof chamber, meaning it burns all the fuel faster and hotter, pushing the piston down sooner. This gives more mechanical leverage on the crankshaft, thus producing more power for a given amount of fuel, at least in principle.

It’s this unique configuration which leads to some interesting design choices with the HEMI’s cylinder head. Unlike a typical pentroof-shaped design, a HEMI uses a dome-shaped chamber with a rounded piston head, functionally increasing the surface area that the explosion pushes on and improving the engine’s volumetric efficiency. However, this increased surface area leads to a number of downsides, the notable ones here being heat and airflow. The more surface area there is, the faster heat dissipates. The airflow tends to get squashed in the sides of a traditional HEMI, which leads to poor efficiency. Moreover, the valves are huge; you simply cannot put a spark plug directly in the middle.
To solve this problem, modern HEMI designs incorporate two spark plugs on opposite ends of the combustion chamber. This ensures a more complete, even, and efficient burn across the entire chamber, as opposed to one centralized explosion which isn’t possible with the head design or airflow pattern. Let’s dive in and discuss how this works.

Airflow and spark in modern HEMI engines
Right off the bat, why do modern HEMI engines have two spark plugs at all when you only need one, aside from the valvetrain? Simple: Modern HEMI engines aren’t actually hemi engines in the traditional sense, and that’s a good thing. As stated before, a true hemi head, while excellent for hotter loads (think high-performance applications), isn’t ideal for passing modern EPA standards.
All those unburnt hydrocarbon emissions sitting so far away from the explosion, tucked away along the sides of the combustion chamber, eventually go out the exhaust and create too much pollutants. The solution Chrysler implemented was to modify the hemispherical chamber design into what’s best described as an oblong spheroid.
If you look at a HEMI piston head, you’ll notice grooves cut into the top. These are called quench pads, designed to swirl airflow in a certain predictable pattern. This allows the combustion process to occur more efficiently and cleanly, flowing like a river throughout the cylinder.

Basically, you want the airflow to reach every part of the combustion chamber for the most efficient burn. It’s like a miniature wind tunnel — if you have a pocket that’s out of the way, it won’t get enough air, whereas other areas get too much airflow. The modern HEMI’s head is designed in such a way to minimize these areas, creating its own unique airflow pattern within the combustion chamber. In order to provide a complete and efficient burn, Chrysler implemented a dual spark plug orientation, with 16 spark plugs across eight cylinders.

The valvetrain simply won’t allow it
One of the benefits of a hemi head is being able to fit larger valves; in the case of modern Gen III HEMIs, these valves are so large that there’s no physical space between them to fit a single spark plug. This means using two spark plugs on either side of the valves, which then necessitates different airflow for a complete burn with two spark plugs, and so on. In other words, this all revolves around the head design and the combustion event’s inconsistency within the domed shape.
Is the second spark plug even necessary, though? In the old days, hemispherical chambered engines have implemented various fixes for the inconsistent combustion event dilemma. Because the more domed you make the chamber, the more disrupted and awkward the combustion process becomes, engineers have attempted fitting different shaped pistons, specialized slots, different chamber and head coatings, and more. Conversely, a modern HEMI’s design differs from the original template in substantial ways, thanks to its more advanced piston configuration. Its coil-on-plug ignition system, coupled with the dual spark plug configuration, leads to a more consistent, reliable, and even burn.
Against the classic (single-plug) HEMI configuration, modern designs offer a far cleaner solution while still making good power. Granted, it might not have the same character as older HEMI designs, but let’s be real: you simply cannot produce such an inefficiently-burning design today and get away with it; the engine would simply produce too many hydrocarbon emissions. In that sense, yes, it’s absolutely worth the trade-off of buying the extra eight spark plugs when you go to change them on your 5.7-liter HEMI.
Instagram verification has become an important feature for creators, influencers, and businesses looking to build trust online. The well-known blue badge confirms that an account truly belongs to the person or brand it represents. Today, Instagram provides two main ways to obtain verification: through a Meta Verified subscription or by qualifying as a notable public figure. Each method comes with its own requirements, approval process, and costs depending on the region.
What Does the Instagram Verified Badge Mean?
A verified profile with a blue badge on Instagram indicates that the profile is genuine and associated with the actual person or brand it claims to represent. The blue badge helps people distinguish between genuine and fake accounts. One should be aware that a verified badge on an Instagram account does not reflect the account’s popularity. There are two ways to get verified on Instagram in 2026. One way is by subscribing to the Meta Verified program, which is paid. The second way is to apply as a public figure or brand that meets Instagram’s requirements for the verified program.

In slightly unexpected news this week, Barco, a Belgian company that specialises in AV projection has just snapped up the Focal / Naim brands for €135 million.
While Focal / Naim is a premium, even luxury brand, I think this deal is different from the spate of acquisitions seen over the last few years, where Bose bought the McIntosh Group, and Harman ate up Sound United.
Those were MA deals where brands were looking to move into more luxury areas of the market, as well as grab a foothold in the growing in-car audio market, too. I suspect that this deal from Barco is more about the custom install space.
Similar to the in-car audio market, this is an area that seems to be growing and growing, though not getting much attention in the mainstream market. But give Naim’s expertise with two-channel amplification, while Focal has pushed towards more immersive sound systems; Barco’s own knowledge in the projection market would make an obvious lining up of all these skills.

Your own private cinema
I can’t really speak to what’s driven interest in the custom install market but there’s increasingly more attention being paid to that area by brands.
Advertisement
Sonos has been a player in that space for years, releasing its Amp Multi as a solution to driving multiple speakers in a custom home audio set-up. Q Acoustics has been making forays into that area with its in-wall systems and speakers, as has Linn Audio and L Acoustics, which if you ever go to a music festival in 2026, you’re likely to hear sound through one of their speakers.
And let’s not forget the likes of Loewe, Sharp, JBL, DALI, all of whom were present at ISE 2026 with their professional AV solutions. I went to an event by a prominent British audio brand (which I’m not allowed to talk about yet) that had a prominent emphasis on custom-install and private cinema-based solutions. There’s even a whole awards show (CEDIA) that’s dedicated to this area of the market.
Advertisement
So it is growing, and given these systems can start in the range of a few hundred Pounds for a speaker, to tens of thousands for kitting out a private cinema, this is an area where there’s a lot of money to be made.
The pandemic has likely contributed to this growth, with people hunkering down in their homes rather than venturing out to the cinema, with video delivery systems such as Kaleidescape that can funnel films to your home network that are arguably even better in terms of quality than 4K Blu-ray.
So Barco’s purchase of Focal / Naim would seem, from what I can see, to be firmly entering an area where they can now offer the visual solution (with its projectors) and the audio solution (with in-wall/ceiling speakers), it seems like a match made on the silver screen. It’s a surprise that no one else made a bid for these brands.
Advertisement
What does it mean for Focal / Naim?
There’s no smoke without fire, and while we’ve seen this deal from Barco’s POV, it’s possible that Focal / Naim were inviting bidders on their part.
Advertisement
But I don’t think Focal / Naim will stop being Focal / Naim. They’re a luxury brand(s) that have done impressive work in the last few years with their streaming products, wireless speakers and large-sized active speakers – so I don’t see much changing on that front.
Focal already covers indoor and outdoor audio solutions – it even has audio solutions for boats, another area I could see Barco pushing into – and Focal has been developing in-car solutions for the likes BWM, Toyota, Tesla, Mercedes, Volkswagen, Ford and others.
Image Credit (Trusted Reviews)
I see the Barco deal enhancing what Focal / Naim already does and not mucking about with its DNA. And I imagine they’ll be a renewed focus on the professional side but considering it exists, and has existed, along with the commercial side for decades, I don’t imagine any disruption to headphones, wireless speakers etc
Advertisement
I could be wrong, but Barco seems to have bought Focal / Naim for what they represent now, rather than purchasing them as a means to turn them into something other than what they are. I sense a “if it ain’t broke, don’t fix it” attitude to this acquisition, which could be a good thing for the future of Focal / Naim.
Recentreports about AI project failure rates have raised uncomfortable questions for organizations investing heavily in AI. Much of the discussion has focused on technical factors like model accuracy and data quality, but after watching dozens of AI initiatives launch, I’ve noticed that the biggest opportunities for improvement are often cultural, not technical.
Internal projects that struggle tend to share common issues. For example, engineering teams build models that product managers don’t know how to use. Data scientists build prototypes that operations teams struggle to maintain. And AI applications sit unused because the people they were built for weren’t involved in deciding what “useful” really meant.
In contrast, organizations that achieve meaningful value with AI have figured out how to create the right kind of collaboration across departments, and established shared accountability for outcomes. The technology matters, but the organizational readiness matters just as much.
Here are three practices I’ve observed that address the cultural and organizational barriers that can impede AI success.
Advertisement
Expand AI literacy beyond engineering
When only engineers understand how an AI system works and what it’s capable of, collaboration breaks down. Product managers can’t evaluate trade-offs they don’t understand. Designers can’t create interfaces for capabilities they can’t articulate. Analysts can’t validate outputs they can’t interpret.
The solution isn’t making everyone a data scientist. It’s helping each role understand how AI applies to their specific work. Product managers need to grasp what kinds of generated content, predictions or recommendations are realistic given available data. Designers need to understand what the AI can actually do so they can design features users will find useful. Analysts need to know which AI outputs require human validation versus which can be trusted.
When teams share this working vocabulary, AI stops being something that happens in the engineering department and becomes a tool the entire organization can use effectively.
Establish clear rules for AI autonomy
The second challenge involves knowing where AI can act on its own versus where human approval is required. Many organizations default to extremes, either bottlenecking every AI decision through human review, or letting AI systems operate without guardrails.
Advertisement
What’s needed is a clear framework that defines where and how AI can act autonomously. This means establishing rules upfront: Can AI approve routine configuration changes? Can it recommend schema updates but not implement them? Can it deploy code to staging environments but not production?
These rules should include three elements: auditability (can you trace how the AI reached its decision?), reproducibility (can you recreate the decision path?), and observability (can teams monitor AI behavior as it happens?). Without this framework, you either slow down to the point where AI provides no advantage, or you create systems making decisions nobody can explain or control.
Create cross-functional playbooks
The third step is codifying how different teams actually work with AI systems. When every department develops its own approach, you get inconsistent results and redundant effort.
Cross-functional playbooks work best when teams develop them together rather than having them imposed from above. These playbooks answer concrete questions like: How do we test AI recommendations before putting them into production? What’s our fallback procedure when an automated deployment fails – does it hand off to human operators or try a different approach first? Who needs to be involved when we override an AI decision? How do we incorporate feedback to improve the system?
Advertisement
The goal isn’t to add bureaucracy. It’s ensuring everyone understands how AI fits into their existing work, and what to do when results don’t match expectations.
Moving forward
Technical excellence in AI remains important, but enterprises that over-index on model performance while ignoring organizational factors are setting themselves up for avoidable challenges. The successful AI deployments I’ve seen treat cultural transformation and workflows just as seriously as technical implementation.
The question isn’t whether your AI technology is sophisticated enough. It’s whether your organization is ready to work with it.

Burson Audio has been building serious headphone amplifiers since the early days of the Head-Fi revolution, long before personal audio became the center of gravity for the hi-fi industry. The Australian company earned its reputation the old-fashioned way: powerful Class A designs, fully discrete circuitry, and desktop components that deliver clean power, expansive soundstages, and connectivity options that make them easy to integrate into modern listening chains.
Now Burson Audio is expanding its lineup with the new Stellar Series, a range of compact Class A desktop components designed to bring more of the company’s flagship engineering to a slightly more approachable tier. The first model, the Conductor Stellar (Standard Edition), combines a high-resolution DAC, Class A headphone amplifier, and desktop preamp into a single chassis priced at $1,799.
Positioned between Burson’s entry-level Playmate 3 ($599 at Apos Audio) and the flagship Grand Tourer range, the Stellar line pulls key elements from the company’s top-tier Voyager Series; Class A muscle, discrete circuit architecture, and the unmistakable Burson house sound—while packaging it all into a more compact and accessible platform.
The timing also makes sense. We recently reviewed the Burson Audio Conductor GT4, and it remains one of the finest desktop DAC/headphone amplifier combinations currently available, delivering the kind of effortless power and wide open presentation that has long defined Burson’s approach to personal audio.

Burson Conductor Stellar
Burson Conductor Stellar: Class A Headphone Amp, DAC and Preamp
At the center of the Burson Audio Conductor Stellar is the ESS9039PRO DAC, paired with Burson’s fully discrete output stage and Max Current power supply architecture. Burson rates the unit at 8 watts of pure Class A output, which is substantial for a desktop headphone amplifier and enough on paper to handle a wide range of headphones, from more sensitive in-ear monitors to far more demanding full-size designs.
The headphone amplifier section has a 0.5-ohm output impedance, which should help it maintain better control with a broad range of headphone loads, while the pre-out and DAC-out stages are rated at 1 ohm and 20 ohms respectively.
Burson is also using a transistor-based amplification stage built around four Onsemi MJE15032 transistors per channel. Those output devices are configured for high Class A bias, which is consistent with Burson’s long-running design approach in the headphone category.
The company also says the Conductor Stellar includes a dedicated low-noise amplification module for IEMs, aimed at reducing hiss with high-sensitivity earphones. Supporting that is the new Silent Power Module 2, built around the LT3045 voltage regulator, which Burson specifies at 0.8 µV RMS noise. In practical terms, the goal here is lower background noise and cleaner low-level detail, especially with sensitive headphones or lower listening volumes.
Advertisement
From a connectivity standpoint, the Burson Audio Conductor Stellar is built as an all-in-one desktop control center. Digital inputs include USB-C, optical Toslink, and coaxial SPDIF, with USB handled by an XMOS platform supporting up to DSD512 and PCM up to 32-bit/768kHz. Coaxial and optical inputs support up to 24-bit/192kHz. Wireless playback is handled by Bluetooth 5.0 using the Qualcomm CSR8675 chipset, with support for LDAC, aptX HD, and AAC. It is also listed as Roon Tested.
On the output side, users get balanced XLR and single-ended RCA preamp outputs, balanced XLR and single-ended RCA line outputs, plus headphone connections in 4-pin XLR, 6.35mm, and 3.5mm formats.
Burson’s published measurements point to a design focused on low noise and wide bandwidth. Physically, the unit measures 210 x 200 x 75 mm or 8.3 x 7.9 x 2.9 inches, and weighs about 5 kg or 11 pounds, which makes it compact by desktop Class A standards, though not exactly featherweight. Class A and “small desktop box” usually have a tense relationship. Physics always sends the bill.

The Three Versions Explained
The Standard version is the entry point into the Stellar range. It ships with NE5532 IC op-amps, the SP01 power module, and a 24V/5A power supply, and it does not include a remote control. This is the version aimed at buyers who may want to experiment later with Burson’s upgrade path rather than paying for everything upfront.
The Deluxe version moves things up with V7 Vivid Pro op-amps, the SP02 power module, Burson’s Super Charger 5A external power supply, and an included remote control. Based on Burson’s own positioning, this is the model intended for buyers who want a more fully optimized setup straight out of the box without stepping all the way to the top trim.
The Max version sits at the top of the range and includes the V7 Vivid Pro op-amps, SP02, and remote as well, but replaces the Super Charger with Burson’s Fusion Core power solution. That makes it the most fully loaded version in the Stellar lineup and the one aimed at users who want the highest-spec factory configuration without adding upgrades later.
All three versions share the same core platform, inputs, outputs, chassis dimensions, and overall functionality. The main differences come down to the op-amp configuration, power supply implementation, and whether a remote is included.
The Bottom Line
At $1,800 for the Standard version, the Burson Audio Conductor Stellar lands in a price tier where most competitors force you to start making trade-offs. Some offer excellent amplification but limited connectivity. Others focus on DAC performance but lack the power to properly drive demanding headphones. Burson is trying to avoid those compromises by delivering a true Class A desktop amplifier with 8 watts of output, a flagship-grade ESS9039PRO DAC, balanced and single-ended connectivity, Bluetooth with LDAC, and a dedicated low-noise IEM stage in one chassis.
Advertisement
The other differentiator is upgradability. Burson’s modular op-amp design and multiple versions mean users can start with the Standard configuration and evolve the system over time rather than replacing the entire unit. That approach remains relatively rare in this category.
Who is it for? Headphone listeners building a serious desktop system who want enough power to drive virtually any headphone, flexible digital connectivity, and a path for future upgrades without jumping immediately into the $3,000–$5,000 range.
What’s missing? Network streaming and a built-in display interface beyond the basics, both of which are appearing more often in this category.
Still, when you look at the landscape, it becomes clear where the Stellar fits. Getting this level of Class A power, connectivity, and upgrade flexibility from competitors such as Schiit Audio, Feliks Audio, Ferrum Audio, or Chord Electronics typically requires multiple components or a significantly larger investment. Burson’s pitch is simple: put most of it in one box, keep it upgradeable, and deliver the kind of clean Class A power the company has been known for since the early days of Head-Fi.
Burson Audio has spent nearly two decades building some of the most powerful and flexible desktop headphone amplifiers in the personal audio space. With the new Soloist Stellar, the Australian manufacturer is focusing on something that many desktop amplifiers still struggle to balance: delivering enough Class A power for demanding full size headphones while also providing the low noise precision required for modern wired in-ear monitors. And in case you might have missed it — wired IEMs are having a bit of a moment.
Priced at $1,500 for the Standard version, the Soloist Stellar is a pure headphone amplifier and preamplifier with no onboard DAC. That design choice is deliberate. Many headphone enthusiasts already own a DAC they prefer, and separating the amplification stage allows Burson to concentrate entirely on clean power delivery, ultra low noise operation, and flexible connectivity for a wide range of headphone and desktop systems.
The Soloist Stellar continues Burson’s long running approach of fully discrete Class A amplification, powered by the company’s Max Current power supply architecture and supported by Silent Power modules for lower electrical noise. The amplifier is rated at up to 8 watts of Class A output, which places it firmly in the category of desktop amplifiers capable of driving everything from efficient dynamic headphones to more demanding planar magnetic designs.
But the real story with the Soloist Stellar is how Burson is addressing the different requirements of wired IEM listeners. Sensitive in ear monitors often reveal noise and gain issues that remain hidden with full size headphones. To address this, Burson added a dedicated IEM amplification module built around dual TPA6120A2 amplifier chips. These chips are known for extremely low distortion—around 0.00014 percent THD+N—along with a very high 1300 V per microsecond slew rate and wide bandwidth. The goal is simple: maintain a pitch black background and precise micro detail even when using highly sensitive earphones.

Volume control is handled by a dual PGA2320 analog resistor ladder system, which allows for extremely accurate channel matching and low distortion. Unlike traditional potentiometers or digital attenuation systems, this approach maintains full signal resolution even at lower listening levels. That matters particularly for IEM listeners who often operate in the lower range of an amplifier’s volume control.
Burson also allows users to fine tune the amplifier through swappable dual op amp stages. Owners can experiment with Burson’s V7 Vivid or V7 Classic op amps, or even compatible third party options, depending on their preferred tonal balance. The Standard version is designed as the starting point for those who enjoy upgrading, while the Deluxe version includes V7 Vivid Pro op amps, Silent Power Level 2 modules, the Super Charger 5A power supply, and a remote control.
For users who want to push the amplifier even further, Burson also offers the Fusion Core upgrade, a GaN based power supply capable of delivering up to 360 watts of ultra low noise DC power to the amplifier stage.
What the Soloist Stellar Offers
From a system integration standpoint, the Burson Audio Soloist Stellar is designed to function as both a high performance headphone amplifier and a desktop preamplifier.
Advertisement
It accepts balanced XLR and single ended RCA inputs, along with a microphone bypass input designed for gaming headsets. Output connections include balanced XLR and single ended RCA preamp outputs, plus a dedicated mono subwoofer output for integration into desktop speaker systems.
For headphone users, Burson provides three connection options: balanced XLR, 6.35 mm single ended, and 3.5 mm outputs. The amplifier also separates its gain and output structure into high power, medium power, and dedicated IEM modes, giving users more flexibility when switching between different types of headphones.
This approach reflects the reality of modern personal audio systems. A listener might move between high impedance dynamic headphones, planar magnetics, and sensitive IEMs in the same setup, each of which places very different demands on the amplifier.

Unlimited Power?
Burson specifies the Soloist Stellar with an input impedance of 40 kΩ, making it compatible with a wide range of DACs and source components. Frequency response is listed at ±1 dB from 0 to 55 kHz, while total harmonic distortion is rated at below 0.0015%.
Channel separation is particularly strong, with 143 dB at 1 kHz and 138 dB at 20 kHz, and the amplifier’s THD+N is specified at 0.0005% at 1 kHz at full scale. Signal to noise ratio varies depending on output mode, reaching 120 dB in the dedicated IEM output stage, which is one of the key areas where the design aims to serve sensitive in ear monitors.
Output impedance is kept very low at 0.5 ohms for the headphone amplifier, helping maintain good damping and compatibility across different headphone loads. The preamp outputs are rated at 1 ohm and 20 ohms, depending on the output stage being used.
Power output scales depending on the headphone impedance and output mode. At 16 ohms, the amplifier can deliver up to 8 watts balanced or 4 watts single ended in its high output mode. At 32 ohms, output drops slightly to 5 watts balanced and 2.5 watts single ended. Even at 300 ohms, the Burson Audio Soloist Stellar can still produce 500 milliwatts balanced or 260 milliwatts single ended, which is enough to drive many high impedance headphones.

The medium and IEM modes reduce output accordingly to maintain lower noise and better control with sensitive earphones.
Physically, the Soloist Stellar measures 210 × 200 × 75 mm (8.3 × 7.9 × 2.9 inches) and weighs about 5 kilograms (11 pounds). That mass reflects the thermal and power demands of a compact Class A amplifier, which runs hotter by design than most desktop headphone amps. In our experience with Burson’s previous models, adequate ventilation is essential, as these amplifiers can run noticeably warm during extended listening sessions.
The Bottom Line
Unlike the Conductor Stellar, which combines a DAC, headphone amplifier, and preamp into a single desktop hub, the Burson Audio Soloist Stellar is focused entirely on pure amplification. There’s no DAC inside, which allows Burson to dedicate the design to delivering high current Class A power, extremely low noise performance, and greater flexibility for users who already own a DAC they like.
What makes the Soloist Stellar stand out is how it balances two very different needs. It offers up to 8 watts of Class A power for demanding full size headphones, while also including a dedicated low noise IEM amplification stagedesigned to avoid hiss and preserve fine detail with highly sensitive earphones. That combination is still surprisingly rare in desktop headphone amplifiers.
Advertisement
The Burson Audio Soloist Stellar is aimed at headphone enthusiasts who want a powerful standalone amplifier that can anchor a serious desktop system, especially those who rotate between full size headphones and wired IEMs. Add in the ability to swap op amps and upgrade the power supply, and it becomes a platform that can evolve over time rather than something that needs replacing when the rest of the system changes.
If you are stuck choosing between the 14-inch MacBook Pro and the 16-inch MacBook Pro with the M5 Max, you now have one more thing to consider, aside from size. The question was always there whether the M5 Max was being held back by the smaller chassis. Now that the test results for both these machines are out, the answer appears to be a resounding yes.
How much performance loss are we talking about?
The folks at Notebookcheck ran the same tests on both 14-inch and 16-inch MacBook Pros powered by top-of-the-line M5 Max chips with 40 GPU cores, and the results were insightful.
Initial benchmarks reveal an 18% improvement in multi-core performance in the MacBook Pro 16 over the MacBook Pro 14. What makes this more impressive is that the 16-inch MacBook Pro achieves this in Automatic mode. Switching to High Power mode will offer even better sustained performance over longer sessions.
Notebookcheck
GPU performance tells a similar story. The MacBook Pro 16-inch scores 12% higher than the 14-inch model in the 3DMark Steel Nomad test. More importantly, the GPU performance was stable under sustained workloads, while the 14-inch model dropped by as much as 25% during the same test.
Why is the bigger laptop performing so much better?
It comes down to heat and power draw. The M5 Max is a powerful chip that consumes a lot of power. During benchmarks, the MacBook Pro 16 pulled 78 watts through its CPU cores, significantly more than the 14-inch model.

It’s because the smaller laptop simply doesn’t have the space to manage that kind of heat effectively. With less room for cooling, the MacBook Pro 14 throttles the chip to protect it, which is what causes the performance drops.
The 16-inch MacBook Pro features a larger chassis, improved airflow, and higher thermal headroom capacity, allowing the M5 Max to sustain peak performance with minimal throttling.
So, should you go for the MacBook Pro 14 or the 16?
If you are a creative professional who needs the M5 Max for demanding tasks, such as video editing or 3D rendering, the MacBook Pro 16 is clearly the better choice. The chip has more thermal headroom in the larger body, and it shows.
That said, if your workload requires this level of power, I would recommend waiting for the Mac Studio with the M5 Max, as it will likely deliver better sustained performance at a lower cost. If your work doesn’t require you to travel much, that would be a better machine in every way than the laptop.
Old laptops have a habit of ending up in a drawer the moment manufacturers stop supporting them, left to gather dust while modern software demands more than they can comfortably give. PearOS exists to change that. It’s a free operating system that breathes new life into neglected hardware, bringing a Mac-like experience complete with a familiar menu bar, a clean dock, and smooth gestures to machines that most people had written off. The latest release, built on Arch Linux and going by the name NiceC0re, is designed to make everyday tasks feel effortless on exactly the kind of hardware that usually gets left behind.
Fire it up for the first time and the Mac influences are impossible to miss. A top menu bar greets you with a stylish pear emblem in place of the Apple logo, and the dock below bounces and magnifies icons in exactly the way you would expect. The full screen app launcher is a dead ringer for Launchpad, complete with categories and smooth animations, and the search tool does a convincing impression of Spotlight, pulling up files, apps, and settings in a matter of seconds. The attention to detail goes well beyond the surface level too. The cursor grows larger when you shake it, discreet pop-up indicators let you know when your microphone or screen sharing is active, and countless other small touches will feel instantly familiar to anyone who has spent time on a Mac. PearOS has clearly set out to recreate that experience as faithfully as possible, just without the price tag that usually comes with it.

The settings menu is laid out in clean, organized columns that anyone who has used a recent version of macOS will navigate without a second thought, with display, sound, and network options all sitting exactly where you would expect them. A few corners are still being tidied up, with certain sections marked as coming soon, but the essentials including brightness, volume, night mode, and power all work exactly as they should. The file manager, PearFinder, rounds things out nicely, taking the bones of a typical Linux tool and wrapping it in a polished new interface complete with the sidebar and preview window.
There is also a browser called Pafari that gets about as close to Safari as you reasonably can without outright copying it, complete with clean tabs, a minimal address bar, and all the usual trimmings. Music playback, photo viewing, and screen capture come preinstalled and ready to go as well, all running on familiar Linux foundations but dressed up with Mac-style icons and fonts that tie the whole experience together.
Getting started is straightforward enough. Download the roughly three gigabyte file from the PearOS website, burn it to a USB drive, and boot up your laptop. The custom installer is built with modern web technology and walks you through each step in plain, clear language, so prior Linux experience is not a requirement. You will need to make a couple of decisions along the way, including which graphics driver to use and whether to go with the latest NVIDIA option or an open source alternative. It is also worth noting that a full wipe of the hard drive is required, so backing up your data beforehand and having a dedicated machine or virtual setup in mind is strongly recommended. After that the installer takes care of the rest, and the whole process should be wrapped up in under an hour on most systems.
