Endor Labs launches free tool AURI after study finds only 10% of AI-generated code is secure

Published

on

Endor Labs, the application security startup backed by more than $208 million in venture funding, today launched AURI, a platform that embeds real-time security intelligence directly into the AI coding tools that are reshaping how software gets built. The product is available free to individual developers and integrates natively with popular AI coding assistants including Cursor, Claude, and Augment through the Model Context Protocol (MCP).

The announcement arrives against a sobering backdrop. While 90% of development teams now use AI coding assistants, research published in December by Carnegie Mellon University, Columbia University, and Johns Hopkins University found that leading models produce functionally correct code only about 61% of the time — and just 10% of that output is both functional and secure.

“Even though AI can now produce functionally correct code 61% of the time, only 10% of that output is both functional and secure,” Endor Labs CEO Varun Badhwar told VentureBeat in an exclusive interview. “These coding agents were trained on open source code from across the internet, so they’ve learned best practices — but they’ve also learned to replicate a lot of the same security problems of the past.”

That gap between code that works and code that is safe defines the market AURI is designed to capture — and the urgency behind its launch.

The security crisis hiding inside the AI coding revolution

To understand why Endor Labs built AURI, it helps to understand the structural problem at the heart of AI-assisted software development. AI coding models are trained on vast repositories of open-source code scraped from across the internet — code that includes not only best practices but also well-documented vulnerabilities, insecure patterns, and flaws that may not be discovered for years after the code was originally written.

Badhwar, a repeat cybersecurity entrepreneur who previously built RedLock (acquired by Palo Alto Networks), founded Endor Labs four years ago with Dimitri Stiliadis. The original thesis was straightforward: developers were becoming “software assemblers,” writing less original code and importing most components from open source repositories. Then came the explosion of AI-powered coding tools, which Badhwar described as “the once in a generation opportunity of how to rewrite software development life cycle powered by AI.”

The productivity gains are real — more efficiency, faster time to market, and the democratization of software creation beyond trained engineers. But the security consequences are potentially devastating. New vulnerabilities are discovered every day in code that may have been written a decade ago, and that constantly evolving threat intelligence is not easily available to the AI models generating new code.

“Every day, every hour, new vulnerabilities are found in software that might have been written 5, 10, 12 years ago — and that information isn’t easily available to the models,” Badhwar explained. “If you started filtering out anything that ever had a vulnerability, you’d have no code left to train on.”

The result is a feedback loop: AI tools generate code at unprecedented speed, much of it modeled on insecure patterns, and security teams scramble to keep up. Traditional scanning tools, designed for a world where humans wrote and reviewed code at human speed, are increasingly overmatched.

How AURI traces vulnerabilities through every layer of an application

AURI’s core technical differentiator is what Endor Labs calls its “code context graph” — a deep, function-level map of how an application’s first-party code, open source dependencies, container layers, and AI models interconnect. Where competitors like Snyk and GitHub’s Dependabot examine what libraries an application imports and cross-reference them against known vulnerability databases, Endor Labs traces exactly how and where those components are actually used, down to the individual line of code.

“We have this code intelligence graph that understands not just what libraries and dependencies you use, but pinpoints exactly how, where, and in what context they’re used — down to the specific line of code where you’re calling a piece of functionality that has a vulnerability,” Badhwar said.

He illustrated the difference with a concrete example. A developer might import a large library like an AWS SDK but only call two services comprising 10 lines of code. The remaining 99,000 lines in that open source library are unreachable by the application. Traditional tools flag every known vulnerability across the entire library. AURI’s full-stack reachability analysis trims those irrelevant findings away.

Building that capability required significant investment. Endor Labs hired 13 PhDs specializing in program analysis, many of whom previously built similar technology internally at companies like Meta, GitHub, and Microsoft. The company has indexed billions of functions across millions of open source packages and created over half a billion embeddings to identify the provenance of copied code, even when function names or structures have been changed.

The platform combines this deterministic analysis with agentic AI reasoning. Specialized agents work together to detect, triage, and remediate vulnerabilities automatically, while multi-file call graphs and dataflow analysis detect complex business logic flaws that span multiple components. The result, according to Endor Labs, is an average 80% to 95% reduction in security findings for enterprise customers — trimming away what Badhwar called “tens of millions of dollars a year in developer productivity” lost to investigating false positives.

A free tier for developers, a paid platform for the enterprise

In a strategic move aimed at rapid adoption, Endor Labs is offering AURI’s core functionality free to individual developers through an MCP server that integrates directly with popular IDEs including VS Code, Cursor, and Windsurf. The free tier requires no credit card, no sign-up process, and no complex registration.

“The idea is that there’s no policy, no administration, no customization. It just helps your code generation tools stop creating more vulnerabilities,” Badhwar said.

Privacy-conscious developers will note a key architectural choice: the free product runs entirely on the developer’s machine. Only non-proprietary vulnerability intelligence is pulled from Endor Labs’ servers. “All of your code stays local and is scanned locally. It never gets copied into AURI or Endor Labs or anything else,” Badhwar explained.

The enterprise version adds the features large organizations need: full customization, policy configuration, role-based access control for teams of thousands of developers, and integration across CI/CD pipelines. Enterprise pricing is based on the number of developers and the volume of scans. Deployment options include local scanning, ephemeral cloud containers, and on-premises Kubernetes clusters with full tenant isolation — flexibility Badhwar said is “the most any vendor offers in this space.”

The freemium approach mirrors the playbook that worked for developer tools companies like GitHub and Atlassian: win individual developers first, then expand into their organizations. But it also reflects a practical reality. In a world where AI coding agents are proliferating across every team, Endor Labs needs to be wherever code is being written — not waiting behind a procurement process.

“Over 97% of vulnerabilities flagged by our previous tool weren’t reachable in our application,” said Travis McPeak, Security at Cursor, in a statement sent to VentureBeat. “AURI by Endor Labs shows the few vulnerabilities that are impactful, so we patch quickly, focusing on what matters.”

Why Endor Labs says independence from AI coding tools is essential

The application security market is increasingly crowded. Snyk, GitHub Advanced Security, and a growing number of startups all compete for developer attention. Even the AI model providers themselves are entering the fray: Anthropic recently announced a code security product built into Claude, a move that sent ripples through the market.

Badhwar, however, framed Anthropic’s announcement as validation rather than threat. “That’s one of the biggest validations of what we do, because it says code security is one of the hottest problems in the market,” he told VentureBeat. The deeper question, he argued, is whether enterprises want to trust the same tool generating code to also review it.

“Claude is not going to be the only tool you use for agentic coding. Are you going to use a separate security product for Cursor, a separate one for Claude, a separate one for Augment, and another for Gemini Code Assist?” Badhwar said. “Do you want to trust the same tool that’s creating the software to also review it? There’s a reason we’ve always had reviewers who are different from the developers.”

He outlined three principles he believes will define effective security in the agentic era: independence (security review must be separate from the tool that generated the code), reproducibility (findings must be consistent, not probabilistic), and verifiability (every finding must be backed by evidence). It is a direct challenge to purely LLM-based approaches, which Badhwar characterized as “completely non-deterministic tools that you have no control over in terms of having verifiability of findings, consistency.”

AURI’s approach combines LLMs for what they do best — reasoning, explanation, and contextualization — with deterministic tools that provide the consistency enterprises require. Beyond detection, the platform simulates upgrade paths and tells developers which remediation route will work without introducing breaking changes, a step beyond what most competitors offer. Developers can then execute those fixes themselves or route them to AI coding agents with confidence that the changes have been deterministically validated.

Real-world results show AURI can already find zero-day vulnerabilities

Endor Labs has already demonstrated AURI’s capabilities in high-profile scenarios. In February 2026, the company announced that AURI had identified and validated seven security vulnerabilities in OpenClaw, the popular agentic AI assistant, which were later acknowledged by the OpenClaw development team. As reported by Infosecurity Magazine, OpenClaw subsequently patched six of the vulnerabilities, which ranged from high-severity server-side request forgery bugs to path traversal and authentication bypass flaws.

“These are zero days. They’ve never been found, but AURI did an incredible job of finding those,” Badhwar said. The company has also been detecting active malware campaigns in ecosystems like NPM, including tracking campaigns like Shai-Hulud for several months.

The company is well-capitalized to sustain its push. Endor Labs closed an oversubscribed $93 million Series B round in April 2025 led by DFJ Growth, with participation from Salesforce Ventures, Lightspeed Venture Partners, Coatue, Dell Technologies Capital, Section 32, and Citi Ventures. The company reported 30x annual recurring revenue growth and 166% net revenue retention since its Series A just 18 months earlier. Its platform now protects more than 5 million applications and runs over 1 million scans each week for customers including OpenAI, Cursor, Dropbox, Atlassian, Snowflake, and Robinhood.

Several dozen enterprise customers already use Endor Labs to accelerate compliance with frameworks including FedRAMP, NIST standards, and the European Cyber Resilience Act — a growing priority as regulators increasingly treat software supply chain security as a matter of national security.

The bet that security can keep pace with autonomous software agents

The broader question hanging over AURI’s launch — and over the application security industry as a whole — is whether security tooling can evolve fast enough to match the pace of AI-driven development. Critics of agentic security warn that the industry is moving too quickly, granting AI agents permissions across critical systems without fully understanding the risks. Badhwar acknowledged the concern but argued that resistance is futile.

“I’ve seen this play out when I was building cloud security products, and people were fearful of moving to AWS,” he said. “There was a perception of control when it was in your data center. Yet, guess what? That was the biggest movement of its time, and we as an industry built the right technology and security tooling and visibility around it to make ourselves comfortable.”

For Badhwar, the most exciting implication of agentic development is not the new risks it creates but the old problems it can finally solve. Security teams have spent decades struggling to get developers to prioritize fixing vulnerabilities over building features. AI agents, he argued, do not have that problem — if you give them the right instructions and the right intelligence, they simply execute.

“Security has always struggled for lack of a developer’s attention,” Badhwar said. “But we think you can get an AI agent that’s writing software’s attention by giving them the right context, integrating into the right workflows, and just having them do the right thing for you, so you don’t take an automation opportunity and make it a human’s problem.”

It is a characteristically optimistic framing from a founder who has built his career at the intersection of tectonic technology shifts and the security gaps they leave behind. Whether AURI can deliver on that vision at the scale the AI coding revolution demands remains to be seen. But in a world where machines are writing code faster than humans can review it, the alternative — hoping the models get security right on their own — is a bet few enterprises can afford to make.

‘No more excuses’ as EU launches free age verification app

Published

on

European Commission President Ursula von der Leyen says the app is technically ready and will be available to citizens soon.

The European Commission yesterday (15 April) unveiled a digital age verification app aimed at shielding children from harmful content online, with European Commission president Ursula von der Leyen declaring there are “no more excuses” for platforms that fail to act.

Announcing the tool in Brussels on Wednesday (15 April), von der Leyen painted a stark picture of the risks children face in the digital world. “One child in six is bullied online. One child in eight is bullying another child online,” she said, warning that social media platforms use “highly addictive designs” that damage young minds and leave children vulnerable to predators.

Users set up the app using a passport or ID card, after which they can confirm their age anonymously. The free app, which the Commission says is technically ready and will soon be available to citizens, allows users to verify their age when accessing online platforms “without revealing any other personal data”, according to von der Leyen. “Users cannot be tracked,” von der Leyen stressed, adding that the app is fully open source and compatible with any device.

Drawing a comparison with the EU’s Covid certificate – adopted in record time and used across 78 countries – von der Leyen said the age verification tool follows “the same principles, the same model.” Seven member states, including France, Italy, Spain and Ireland, are already planning to integrate the app into their national digital wallets.

The announcement comes ahead of the second meeting of the Commission’s Special Panel on Children’s Safety Online, which is due to deliver its recommendations by summer. Von der Leyen was unambiguous about the Commission’s direction of travel on enforcement. “Children’s rights in the European Union come before commercial interest. And we will make sure they do.”

Platforms were put on notice that voluntary compliance alone will not suffice. “We will have zero tolerance for companies that do not respect our children’s rights,” she said, adding that the Commission is “moving ahead with full speed and determination on the enforcement of our European rules”.

Blue Origin’s New Glenn put a customer satellite in the wrong orbit during its third launch

Published

on

Jeff Bezos’ space company Blue Origin successfully re-used one of its New Glenn rockets for the first time ever on Sunday, but the company failed at its primary mission: delivering a communications satellite to orbit for customer AST SpaceMobile.

AST SpaceMobile issued a statement Sunday afternoon that the upper stage of the New Glenn rocket placed BlueBird 7 satellite into an orbit that was “lower than planned.” The satellite successfully separated from the rocket and powered on, the company said, but the altitude is too low “to sustain operations” and will now have to be de-orbited — left to burn up in the atmosphere of Earth.

The cost of the loss of the satellite is covered by AST SpaceMobile’s insurance policy, according the company, and there are successive BlueBird satellites that will be completed in around a month. AST SpaceMobile has contracts with more than just Blue Origin, and the company said it expects to be able to launch 45 more to space by the end of 2026.

But this represents the first major failure for Blue Origin’s New Glenn program, which only made its first flight in January 2025 after more than a decade in development. This was the second mission where New Glenn carried a customer payload to space, after launching twin spacecraft bound for Mars on behalf of NASA last November. The company did not immediately respond to a request for comment.

The apparent failure of New Glenn’s second stage could have wider implications beyond Blue Origin’s near-term commercial ambitions. The company is pushing hard to become one of the main launch providers for NASA’s Artemis missions to the moon and beyond. The space agency — and the Trump administration — has put pressure on Blue Origin and SpaceX to be able to put landers on the moon by the end of President Donald Trump’s second term, before advancing to returning humans to the lunar surface.

Blue Origin CEO Dave Limp has even said his company “will move heaven and Earth” to help NASA get back to the moon faster.

Blue Origin recently completed testing its first version of its own lunar lander, which the company is expected to try and launch at some point this year (without any crew). Blue Origin had suggested last year that it was considering launching this lander on New Glenn’s third mission, but ultimately decided to launch the AST SpaceMobile satellite instead.

The third New Glenn launch seemed to start just fine on Sunday, with the the mega-rocket lifting off at 7:35 a.m. local time from Cape Canaveral, Florida. It was the first time Blue Origin re-used a previously-flown New Glenn booster — the same one that flew during New Glenn’s second mission. Roughly 10 minutes after liftoff, the booster came back down and landed on a drone ship in the ocean, just like it had last November. Jeff Bezos even shared drone footage of the booster’s landing on X, the social media site owned by his rival Elon Musk. (Musk offered congratulations.)

Roughly two hours after the launch, though, Blue Origin announced in its own post that the New Glenn upper stage placed AST SpaceMobile satellite in an “off-nominal orbit.” The company has not released any more information since that post.

Blue Origin spent a long time developing New Glenn, and it has been taken as a sign of confidence in that process that the company decided to start launching commercial payloads during these early missions. By comparison, SpaceX has spent the last few years flying test versions of its massive Starship, but has stuck with using dummy payloads as it works out the rocket’s kinks.

SpaceX did lose payloads deeper into its Falcon 9 program. In 2015, on the 19th Falcon 9 mission, the rocket blew up mid-flight and lost an entire International Space Station cargo spacecraft. In 2016, a Falcon 9 exploded on the launch pad during testing, causing the loss of an internet satellite for Meta.

What Is The ‘Green Wave’ When It Comes To Traffic Lights?

Published

on





There are many drivers who often bemoan the very existence of traffic lights. Despite incurring the daily ire of commuters who are running late for work, even those haters have to acknowledge the traffic signal’s invaluable function in helping to keep our roadways safe.

Traffic signals have, of course, evolved considerably since they were first pressed into use in the late-1860s, with the first electric lights coming into play sometime around 1912. It wasn’t long until those signals started using colored lights, and have since evolved into the red, yellow, and green modes we are all too familiar with today. Even as safety remains the primary purpose of the hundreds of thousands of traffic lights currently employed throughout the United States, some theorize that the life-saving devices may one day cease to exist

Until that fateful day, getting stuck at red lights when you’re in a rush will remain a constant source of commuter frustration. On some occasions, however, a stream of greens opens up on the road ahead like the parting of the Red Sea. That stream of green has a name, with researchers dubbing it the “Green Wave.” While they may seem rare, the “Green Wave” is a common occurrence in certain parts of the world, and it serves a very important purpose.

What is the purpose of a traffic light Green Wave?

While it might seem like a weird sort of karmic intervention, that “Green Wave” of traffic lights was actually programmed for a specific purpose by whatever government organization is in charge of maintaining the traffic signals in your city, state or township. They are, however, far more commonly utilized on high-volume roads in urban areas. The purpose of a “Green Wave” is to improve the flow of traffic in those areas, particularly during times with increased traffic volume. 

At its core, the concept is very simple. The idea is to keep traffic flowing during peak volume times by simply reducing the number of stops at concurrent traffic signals. To enact a “Green Wave,” planners and engineers simply synchronize the traffic lights in congested areas to all turn green at the same time and stay that way for a specified period that ensures a steady flow of traffic in one direction. The method is, naturally, easier to manage on one-way streets with no turning lanes, though some cities have attempted to aid traffic flow further by simply outlawing left turns in metropolitan areas. Some have even taken to banning right turns too

Advertisement

In any case, on top of aiding the flow of traffic in congested areas, “Green Wave” traffic patterns are also believed to have a positive effect on the environment. After all, the reduction in stop-and-go traffic also reduces a vehicle’s idling time, which, in turn, leads to reduced greenhouse gas emissions.

Digit Humanoid Nails a 65-Pound Deadlift and Reveals How Agility Trains Its Robots

Published

on

Agility Digit Humanoid Robot Deadlifting Weightlifting
Digit is seen performing deadlifts with a 65-pound weight in the center of a lab. Agility Robotics shared the video a few days ago, and to be honest, the robot maintains a fairly steady balance and completes the task from beginning to end. Someone mentions that the new version can lift significantly more weight than the previous one, while another laughs about how it can run all day without stopping.



The engineers designed the test so that Digit had to work harder than usual. Every additional pound it must lift causes the robot to modify its entire body at simultaneously, including its arms, legs, torso, and everything else. The system must keep the weight centered and avoid tipping over, therefore the legs, arms, and rest of the robot must all function together. These actuators and joints can withstand repeated load without breaking down. Digit’s video simply shows the robot grasping the weight, rising up, then effortlessly placing it down repeatedly in a standard indoor location built for people.


Unitree G1 Humanoid Robot(No Secondary Development)
  • Sleek & Durable Design: Standing at 132cm tall and weighing only approx. 35kg, the G1 is constructed with aerospace-grade aluminum alloy and carbon…
  • High Flexibility & Safe Movement: Boasting 23 joint degrees of freedom (6 per leg, 5 per arm), it offers an extensive range of motion. For safety, it…
  • Smart Interaction & Connectivity: Powered by an 8-core high-performance CPU and equipped with a depth camera and 3D LiDAR. It supports Wi-Fi 6 and…

Simulation is where all of the training takes place, because before it touches a real weight, an engineer creates a digital copy of the same thing in a virtual world. Then they anticipate what will happen when the weight shifts. The grip pressure remains constant, with no slipping or lowering. Any changes to the robot’s equilibrium are registered extremely instantly. The policy learns the perfect lift in the simulated environment with no complications before being transmitted directly to the real robot. When you see the real robot perform it, it looks fairly natural because it has already handled every potential variable thousands of times in the simulation.

Agility Digit Humanoid Robot Deadlifting Weightlifting
Engineers chose deadlifts for the test because the movement requires complete body control. A simple arm raise would not put the hardware under the same level of stress. By incorporating weight into the simulation loop, the team is able to handle balancing changes that a pre-programmed script cannot handle alone. As a result, Digit lifts consistently, with no wobbling or resets. This method is easily adaptable to other objects or larger loads in future tests.

Digit was built by Agility to manage long, repetitive jobs that wear people out, such as working in factories or warehouses where you must squeeze into tight spaces, pick up oddly shaped goods, and continue without taking a break. This deadlift test demonstrates Digit’s ability to lift weight on ordinary floors while remaining steady, which is ideal for picking up boxes, carrying tools, and stacking things in human-designed places.

Advertisement

It also illustrates how far they’ve come in teaching robots to perform physical tasks. Whole-body synchronization was originally a nightmare, with hand-tuned code for each joint angle. But now they can simply train a policy in simulation that adapts on the go. Digit detects weight using its sensors, corrects itself in real time, and completes the lift without assistance, while the hardware can keep up because the training has already taught the actuators and joints to be more durable.

Is the Iran War Driving a Surge of Interest in Electric Cars?

Published

on

In October and through November, America’s EV sales reached their lowest point since 2022 after government subsidies expired, remembers Time. “But first-quarter data for 2026 shows that used EV sales were 12% higher than the same time last year and 17% higher than the previous quarter.

“One factor likely helping push buyers toward these cars is high gas prices, which recently topped $4.00 a gallon for the first time in four years,” they write — but it’s not just in the U.S. Instead, they argue the conflict “is driving a global surge of interest in electric vehicles…”


In the U.K., electric car sales reached a record high, with 86,120 vehicles sold in March… The French online used-car retailer Aramisauto reported its share of EV sales nearly doubled from February 16 to March 9, rising to 12.7% from 6.5%, while sales of fueled models dropped to 28% of sales from 34%, and sales of diesel models dropped to 10% from 14%. Germany’s largest online car market, mobile.de, told Reuters that the share of EV searches on its website has tripled since the start of March — from 12% to 36%, with car dealers receiving 66% more enquiries for used EVs than in February.

South Korea reported that registrations for electric vehicles more than doubled in March compared to the prior year, due in part to rising fuel prices and government subsidies… In New Zealand, more than 1,000 EVs were registered in the week that ended on March 22, close to double the week before, making it the country’s biggest week for electric vehicle registrations since the end of 2023, according to the country’s Transport Minister, Chris Bishop.

In America, Bloomberg also reports 605 high-speed EV charging stations switched on in just the first three months of 2025, “a 34% increase over the year-earlier period,” according to their analysis of federal data. A data platform focused on EV infrastructure tells Bloomberg that speedier and more reliable chargers are convincing more drivers to go electric and use public plugs.

La Dolce Audio Current Drive Tube Amplifiers Have a Different Take on Valve Amplification: AXPONA 2026

Published

on

Most loudspeaker designers don’t spend much time debating open versus closed the way headphone enthusiasts do. Cabinets are part of the equation for a reason, offering control, efficiency, and predictable performance. That’s the accepted playbook. But like any good rule in audio, someone is always trying to break it.

At AXPONA 2026La Dolce Audio showed what happens when you ignore that playbook and lean into experimentation. Founder Terry Gesualdo isn’t approaching amplification or speaker design from a traditional standpoint, he’s part of a growing group of builders exploring open designs and current drive amplification as an alternative to the usual voltage driven norm.

I met Gesualdo on the shuttle ride over to the show, which feels about right. This isn’t a polished, corporate origin story, it’s the familiar path of someone who started by modifying gear, then building his own tube amps for himself, then for friends and family. The difference here is that he didn’t stop at tweaking circuits. He kept pushing until the results looked and sounded like something entirely his own.

Current Drive Tube Amplification: Why La Dolce Audio Isn’t Following the Script

Having built a few tube amps, I’m always curious to see what others are doing, and Terry Gesualdo is not following the usual path. Most of his designs are single ended pentode circuits, not triodes, and not push pull designs chasing more voltage swing. That choice alone puts him in a different lane than a lot of tube builders.

Advertisement

Where things really diverge is the move to current drive. Most amplifiers are voltage driven. That’s the standard approach across both solid state and tube designs. Current drive shows up more often inside DACs where signal levels are extremely small, and occasionally in headphone amplifiers, but rarely in loudspeaker systems where current demands are far higher.

la-dolce-amps-rack-axpona-2026

The idea behind current drive is fairly straightforward. By controlling current instead of voltage, the amplifier reduces the impact of back EMF from the driver. That back EMF is the voice coil behaving like a generator as it moves through the magnetic field, feeding energy back into the amplifier. Reduce that interaction and, in theory, you reduce distortion and improve control over the driver.

It’s not a new concept, but it’s one that almost nobody is applying to loudspeakers in this way, especially with tube amplification. That’s what makes what La Dolce Audio is doing worth paying attention to.

Control Over Harmonics Instead of Chasing Purity

Circling back to that idea of ignoring the usual playbook, another aspect that reinforces how La Dolce Audio is taking a different path is the near exclusive use of pentode tubes instead of the more common triodes. Triodes are the simplest form of amplification with three active elements, anode, cathode, and grid. Fewer parts in the signal path is why many listeners and designers gravitate toward them. The assumption is less complexity means lower distortion and fewer unwanted artifacts.

But that’s only part of the story. Harmonic distortion doesn’t disappear just because the circuit is simpler. It just changes character. And not all harmonics are a problem. A lot of what people describe as tube warmth comes from second and third order harmonics, which many listeners actually prefer.

Terry Gesualdo leans into that reality rather than trying to avoid it. By using pentodes, which add additional control elements beyond what a triode offers, he can shape those harmonic structures instead of accepting whatever the circuit gives him. That includes adjusting the balance between second and third order harmonics and even their phase relationships.

It’s a different mindset. Instead of chasing the lowest possible distortion number, the goal is control over how that distortion presents itself, and giving the listener a way to fine tune the result.

Advertisement. Scroll to continue reading.

Some will find that approach a bit sacrilegious. There’s a large part of the hobby focused on removing as much of this behavior as possible, chasing lower distortion numbers and cleaner measurements. That’s not the goal here.

Advertisement

La Dolce Audio leans into a different philosophy. “If it sounds good, do it” is more than a slogan. It reflects the idea that listening is subjective and that not every system needs to be locked into a single interpretation of neutrality. By giving users control over harmonic structure, the design puts some of that decision making back in the listener’s hands.

UA2.5 and UA2.5M: Modular Power and User Tunability

ua-25m-angle
La Dolce Audio UA2.5M monoblock

La Dolce Audio offers two amplifier paths built around the same core ideas but with different roles. The UA2.5 is a dual channel amplifier rated at roughly 3 to 5 watts depending on tube selection, and it’s where most of the flexibility lives. With 24 possible sound signatures, it gives the user direct control over how the amplifier presents harmonic content and overall character.

The UA2.5M monoblocks step things up in output, delivering around 9 watts per channel, but they take a more focused approach. They are designed to be paired with the UA2.5, which handles preamp duties and sound shaping. As a result, the monoblocks do not include the same tuning controls, focusing instead on providing additional power while maintaining the same underlying design philosophy.

HPA2.3 Headphone Adapter

hpa-23-ua-25-front
La Dolce Audio UA2.5 Tube Amplifier (top) with HPA2.3 Headphone Adapter (bottom)

Alongside its amplifiers, La Dolce Audio offers the HPA2.3 headphone “amplifier,” although that label needs a bit of clarification. It’s not an amplifier in the traditional sense. The HPA2.3 is a passive device designed to work with the UA2.5, relying on it for signal processing and gain. In practice, it converts the UA2.5 into a headphone amplifier rather than operating as one on its own.

That means the HPA2.3 can drive a wide range of headphones depending on how the UA2.5 is configured, but it cannot function independently. No preamp, no sound.

Pricing reflects that modular approach. The UA2.5, which serves as the foundation of the system, runs between $1,799 and $2,499 depending on configuration and tube selection. The UA2.5M monoblocks are $1,999 each, and the HPA2.3 adds another $599. A full system lands in the $3,500 range, depending on how far you go down the rabbit hole.

The Bottom Line

La Dolce Audio isn’t trying to fit into the usual mold, and that’s the point. In a category where a lot of designs feel like small variations on the same theme, this is a reminder that there are still different ways to approach amplification and system building.

Beyond the amplifiers, the partnership with ABX Audiophiles on Discord to offer open baffle speaker kits adds another layer. It invites listeners to get involved, not just as buyers but as participants, with a community that shares ideas, solves problems, and pushes designs forward together. We’ll have more on that ABX side of things in a forthcoming article.

It won’t be for everyone. If you want plug and play simplicity, this isn’t it. But if you’re the type who likes to understand what your system is doing and shape it to your preferences, La Dolce offers something most companies don’t. A system you can actually interact with, not just listen to.

Hisense U7SG TV Review (2026): Better Design, Great Value

Published

on

Unlike previous years in what TV nerds like me call the “brightness wars,” the U7SG doesn’t outblast its predecessor, but it’s not a problem. It gets around three times as bright as anything you can stream (which is naturally capped due to compression), and has enough firepower for all but the flashiest 4K HDR Blu-rays. Its color processing shows a little more restraint than in previous models. It’s not quite what I’d call “accurate to the director’s intent,” like the best TVs I test, but it does keep itself from blasting your eyeballs most of the time.

The high brightness is matched by deep black levels, without much of the “blooming” or “haloing” around bright objects that can dilute the contrast of many budget-friendly TVs. It’s not as striking as OLED TVs, which can control each of their millions of pixels on demand, but it’ll wow you in deep space scenes just the same. I was pleased that the TV’s odd local dimming issue didn’t crop up in real-world content, but the picture does tend to flatten shadows in dark scenes more than expected, even as the matte-like screen does a good job keeping reflections at bay.

There are some other notable flaws. Moving off to the TV’s side in my easy chair led to dimmer colors, washed-out contrast between the brightest and darkest images, and uneven backlighting, aka the “dirty-screen effect.” That stood out most in the green backdrop of the Masters on Sunday as Rory McIlroy held on for the win. It wasn’t an issue when viewing head-on, but even then, I noticed some dingy yellow lines along the screen’s left and right sides with light backgrounds. (I may not have noticed them much if I hadn’t been bombarding this TV with test content first.)

The U7SG still doesn’t feel quite like a premium model. But it’s a very clear, bright TV, and will feel more like it’s worth the money once RGB shows up on other Hisense models and the price on this one drops. If you want something brighter than a similarly priced OLED like the LG B5, the U7 is a great buy and has a few good upgrades over last year’s U75QG.

We’ll know more about the 2026 TV landscape once the new RGB TVs have landed, but if you need a powerful, classy-looking TV before then, the U7SG should be on your list.
