Although not a typical focus of people who fly quadcopter drones for a hobby or living, endurance flying has a certain appeal to it for the challenge it offers. Thus, as part of his efforts to collect all the world records pertaining to quadcopter drones, [Luke Maximo Bell] has been working on a design that would allow him to beat the record set by SiFly Aviation at 3 hours and 11 minutes.
By using knowledge gained from his PV solar-powered quadcopter, [Luke] set about to take it all a few steps further. The goal was to get as much performance out of a single Watt, which requires careful balancing of weight, power output and many other parameters.
Crucial is that power usage goes up drastically when you increase the RPM of the propellers, ergo massive 40″ propellers were picked to minimize the required RPM to achieve sufficient lift, necessitating a very large, but lightweight frame.
The battery packs are another major factor since they make up so much of the weight. By picking high-density Tattu batteries and stripping these down even more this was optimized for as well, before even the wire gauge of the power wires running to the motors were investigated to not waste a single Watt or gram.

All of this seems to have paid off, as a first serious test flight resulted in a 3 hour, 31 minutes result, making it quite feasible that [Luke] will succeed with his upcoming attempt at the world’s longest flying electric multirotor record. Another ace up his sleeve here is that of forward movement as well as wind provides effectively free lift, massively reducing power usage and possibly putting the 4 hour endurance score within easy reach.
At $999, the iFi Audio NEO iDSD 3 lands in a price bracket that’s starting to feel less taboo in 2026, and that’s not an accident. In a Head-Fi market crowded with competent boxes chasing the lowest possible number, iFi is playing a slightly different game: value through consolidation. The NEO iDSD 3 isn’t trying to be the cheapest DAC/headphone amp on your desk. It’s trying to be the one that makes you stop shopping. With serious output power, lossless Bluetooth, full-tilt hi-res playback, and both analog and digital flexibility in a single chassis, iFi is betting that “affordable” no longer means stripped down, but the last box you are likely to need for many years. Which is probably not a thing for some people, but it’s a concept worth thinking about.
Yes, you can spend less with brands like Shanling, FiiO, Schiit Audio (once you start stacking boxes), Topping, or Fosi Audio. The argument isn’t whether $1,000 is cheap—it isn’t. The real question is whether any of those alternatives deliver this level of power, codec support, DAC performance, and feature depth in one box without meaningful compromises. That’s where the NEO iDSD 3 makes its case: not as a bargain-bin hero, but as a compact, do-everything desktop component that treats flexibility and sound quality as non-negotiable.
What the iFi NEO iDSD 3 Actually Is
The iFi Audio NEO iDSD 3 is a compact desktop DAC and headphone amplifier designed to cover a lot of ground without forcing users into a stack of separate boxes. At $999, it sits squarely in the middle of a crowded category, but its pitch is straightforward: combine high-power headphone amplification, full hi-res wired playback, and current-generation lossless Bluetooth support in a single, flexible component that works equally well on a desk or in a traditional hi-fi system.
At its core is iFi’s custom Burr-Brown DAC stage, supporting PCM up to 768kHz and DSD512, paired with revised internal circuitry aimed at improving accuracy rather than adding coloration. JVCKENWOOD’s K2HD Technology is included to restore harmonic content in digital recordings, while the headphone stage delivers up to 2,532mW RMS (5,551mW peak).

Wireless is treated as a primary input, not an afterthought. Bluetooth 5.4 with aptX Lossless, LDAC, and LHDC allows the NEO iDSD 3 to function as a serious wireless DAC. Analog-domain tuning is handled via XBassII and XSpace, for users who want subtle low-frequency reinforcement or a broader presentation without relying on DSP.
Practical details round out the package. The iFi Nexis app enables OTA firmware updates and remote control, and a 2-inch rotating color display allows the unit to be positioned vertically or horizontally depending on system layout.
The NEO iDSD 3 doesn’t try to redefine desktop audio. It focuses on consolidation: strong output power, modern wireless support, broad format compatibility, and real-world usability in one box. Whether that justifies $1,000 depends on your specific priorities, but in terms of scope, it’s clear what iFi is aiming to deliver.
Connectivity
The NEO iDSD 3 is designed to handle both modern digital sources and older analog gear without adapters or workarounds. Digital inputs include USB-B 3.0, S/PDIF coaxial, and S/PDIF optical, covering computers, streamers, TVs, and disc players with digital outputs.
For system integration, the NEO iDSD 3 offers balanced XLR and single-ended RCA line outputs, selectable as fixed or variable, allowing it to function as a DAC, preamp, or headphone amp depending on the setup. A BNC clock input is also included for users running an external master clock.

One notable change from earlier models is the removal of the 3.5mm analog input, replaced by a single-ended RCA line input. This makes the NEO iDSD 3 far more practical for traditional sources such as a turntable with a built-in phono preamp, an external phono stage, a tuner, or older CD players without digital outputs. Yes, that includes legacy gear that still works perfectly fine but predates modern digital connectivity.
Power and Physical Specs
The headphone amplifier section is built to cover a wide range of loads. Output power reaches 2,532mW RMS (5,551mW peak) from the 4.4mm balanced output, with the 6.3mm single-ended output also providing substantial drive. Output impedance is kept low at ≤1Ω, with iEMatch available for sensitive earphones, allowing the unit to work equally well with IEMs, dynamic headphones, and demanding planar designs.

The Bottom Line
The NEO iDSD 3 is a DAC and headphone amplifier that focuses on doing fewer things well, rather than trying to be an all-in-one. What’s unique is the combination of high headphone output power, lossless Bluetooth support, broad digital format compatibility, and a proper RCA analog input in a compact chassis. That last point matters if you’re connecting an external phono stage, a turntable with a built-in phono preamp, or older sources that don’t offer digital outputs.
What it doesn’t include is a built-in streamer or phono stage, by design. If you want network playback, you add one upstream—such as iFi’s ZEN Stream 3 or NEO Stream 3—and keep the DAC and amplifier roles clearly defined.
The NEO iDSD 3 is best suited for listeners who want one capable desktop or rack-friendly component to handle headphones, active speakers, wired sources, and modern wireless playback, without stacking multiple boxes or paying for features they won’t use.

Uber plans to invest $100 million in EV charging infrastructure to support current and future robotaxi fleets in cities like Los Angeles, the Bay Area, and Dallas, “eventually partner[ing] with multiple robotaxi companies on actual robotaxi deployment — WeRide, Waabi, Lucid, Nuro, May Mobility, Momenta, and Waymo of course,” reports CleanTechnica. From the report: “Cities can only unlock the full promise of autonomy and electrification if the right charging infrastructure is built for scale. That infrastructure needs to work for today’s drivers and the fleets of the future,” said Uber’s global head of mobility, Pradeep Parameswaran. In addition to building some infrastructure itself, the company is making “utilization guarantee agreements” with EVgo for various major US cities as well as Electra, Hubber, and Ionity in Europe.
On Uber’s latest shareholder call, CEO Dara Khosrowshahi said that the company would make “targeted growth-oriented investments aligned with the 6 strategic areas of focus.” That includes self-driving vehicles/robotaxis. “With the benefit of learning from multiple AV deployments around the world, we’re more convinced than ever that AVs will unlock a multitrillion-dollar opportunity for Uber. AVs amplify the fundamental strengths of our platform, global scale, deep demand density, sophisticated marketplace technology, and decades of on-the-ground experience matching riders, drivers, and vehicles, all in real time,” Khosrowshahi added.
The sub $1,000 network streaming market is no longer short on options. Between WiiM, Eversolo, Bluesound, and Cambridge Audio, buyers can choose from a wide range of compact streamers that handle modern services cleanly and integrate easily into existing systems. Most now cover the basics well. What separates them is how they integrate into real world systems, the flexibility they give users, and their performance in everyday listening.
That is where iFi Audio positions the $999 NEO Stream 3 and$399 ZEN Stream 3. Both are built around a modern streaming platform that supports Qobuz Connect, TIDAL Connect, Spotify Connect, and Apple AirPlay 2, allowing users to stream directly from native apps without workarounds or proprietary control layers. Setup is handled through a straightforward IoT process, and ongoing updates are managed through iFi’s Nexis platform rather than requiring users to chase firmware manually.
In practical terms, the NEO Stream 3 is designed for listeners who want a single box that can act as the digital front end of a system, handling streaming duties and conversion without external hardware. The ZEN Stream 3 takes a different approach, focusing on being a quiet and reliable network transport for systems that already have a DAC the owner likes and does not want to replace. Both models lean on improved power design and noise reduction to keep the signal path stable, an area where iFi has traditionally focused its engineering effort.
But is that enough to compete below $1,000? Let’s take a look at what both offer straight out of the box.

NEO Stream 3 and ZEN Stream 3 Share the Same Core Streaming and Noise Control Architecture
Both the NEO Stream 3 and ZEN Stream 3 are built on the same core streaming and noise-control platform, with differences that are deliberate rather than cosmetic. At a baseline level, both models receive refinements to their power supplies, including upgraded polymer capacitors for lower noise delivery and the continued use of ELNA Silmic II capacitors in the audio path. The goal here is consistency and stability, not tonal revoicing, with iFi focusing on cleaner power and predictable behavior in long-term use.
Setup and system management are also shared. Both streamers now include iFi’s updated IoT hardware, enabling faster initial configuration and smoother day-to-day operation.Firmware updates and system control are handled through either a browser based interface or the iFi Nexis app, streamlining setup and ongoing maintenance compared with earlier manual update processes. Exclusive Modes return on both units as well, allowing users to disable unused background processes during playback to minimize potential noise sources.
Noise mitigation remains a defining design priority across both products. Each includes iPurifier2 technology on the S/PDIF outputs and Active Noise Cancellation on the USB ports, specifically aimed at reducing interference from connected storage devices or computers when feeding an external DAC.
The NEO Stream 3 goes further by retaining the OptiBox optical isolation system from the original NEO Stream, which isolates the wired network connection and prevents network-borne electrical noise from entering the audio system. The ZEN Stream 3 does not include OptiBox as one its connectivity features.
On the software side, both units use the latest version of iFi’s ultra-resolution streaming engine. This platform supports Qobuz Connect, TIDAL Connect, Spotify Connect, and AirPlay 2, with improvements focused on stability, smoother web radio playback, and a cleaner interface with deeper configuration options. Control is handled through native apps rather than forcing users into a proprietary ecosystem. Support for Spotify Lossless, however, is still not finalised but we’re told it’s coming.

Where the two models clearly diverge is in system role. The NEO Stream 3 is designed as an all-in-one digital front end, combining network streaming with an integrated DAC capable of handling up to 768 kHz PCM and DSD512. It is intended for users looking to modernize an existing hi-fi system without adding external digital components. The ZEN Stream 3, by contrast, is a dedicated network transport. It supports up to 384 kHz PCM and DSD256 and is meant to slot into systems where a preferred external DAC is already in place.
Both models also incorporate K2 technology developed in collaboration with JVCKENWOOD. This processing is designed to restore harmonic information often lost during recording, mastering, or encoding. Two modes are available: K2, which preserves the original file resolution, and K2HD, which optionally upsamples PCM content to 192 kHz 24-bit. With this generation, K2 processing is no longer limited to internal DACs. Any external DAC connected to either streamer can benefit from K2 processing, while the NEO Stream 3 adds the ability to apply K2HD upsampling internally to PCM material below 192 kHz.

NEO Stream 3
The NEO Stream 3 is a combined network streamer and DAC designed to function as a complete digital source component. It supports Wi-Fi and wired networking via RJ45 Ethernet as well as iFi’s M12-X optical network input. Digital inputs include USB-A for storage or DAC use and a front-mounted USB-C port. Digital outputs are comprehensive, with dual USB-A, S/PDIF optical, S/PDIF coaxial, AES/EBU, and I2S, allowing the unit to operate either as a DAC or as a dedicated digital transport. Analog outputs are provided via a balanced 4.4 mm connection and single-ended RCA.
Internally, the NEO Stream 3 uses a Burr-Brown DAC stage derived from the NEO iDSD 2 and supports high-resolution audio up to 768 kHz PCM and DSD512. Balanced output voltage is rated at 4 V RMS, with 2 V RMS available from the RCA outputs.

Power is supplied via a DC input supporting 9 to 15 volts, with internal regulation using upgraded polymer capacitors and ELNA Silmic II capacitors. Power consumption is under 0.5 watts at idle and approximately 14 watts at maximum load.
Setup and ongoing updates are handled through a simple browser-based interface or the iFi Nexis app, made possible by the new IoT hardware, so there is no need to fuss with manual update routines. With a compact chassis measuring 214 x 151 x 41 mm (8.4 x 5.9 x 1.6 inches) and weighing just 1 kg (2.26 lbs), the NEO Stream 3 is easy to place on a desk or equipment shelf without demanding much space.
The ZEN Stream 3 is designed as a dedicated network transport for systems where digital conversion is handled elsewhere. It focuses entirely on getting a clean, stable digital signal out to an external DAC rather than duplicating functionality already present in many higher-end systems. Networking is handled via Wi-Fi or RJ45 Ethernet, with two USB-A ports available for local storage or DAC output.
Digital output options include two USB-A outputs for DAC connection and a coaxial S/PDIF output, each incorporating iFi’s iPurifier and Active Noise Cancellation technologies to reduce electrical noise before the signal reaches the DAC. There are no analog outputs and no internal DAC, which keeps the signal path simple and aligned with its role as a transport.

High-resolution support extends up to 384 kHz PCM and DSD256, handled by the same next-generation streaming engine used in the NEO Stream 3. Streaming is managed directly through native apps with support for Qobuz Connect, TIDAL Connect, Spotify Connect, and AirPlay 2, avoiding reliance on proprietary control software. K2 processing is included to restore harmonic information lost during recording or encoding and is applied before the digital output, allowing connected DACs to benefit without altering their internal architecture.
Power delivery has been revised with upgraded polymer capacitors and ELNA Silmic II capacitors to improve stability and reduce noise under load. Power is supplied via a DC input supporting 9 to 15 volts, with idle consumption under 6 watts and a maximum draw of approximately 10 watts. Firmware updates and system setup are handled through a rear USB-C service port, using either a browser-based interface or the iFi Nexis app, enabled by the updated IoT hardware platform.
Physically, the ZEN Stream 3 is compact and lightweight, measuring 158 x 100 x 35 mm (6.2 x 3.9 x 1.4 inches) and weighing 578 g (1.27 lbs). It is sized to sit easily on a desktop or equipment shelf alongside an external DAC, making it a practical drop-in upgrade for your existing system.
With competition this strong, iFi is not trying to win by simply piling on features. The strategy here is differentiation through system role, execution, and the details that tend to matter after the initial setup. That includes easy integration into existing systems, app-native control rather than closed ecosystems, and a design that stays below the psychological $1,000 threshold while still targeting more demanding listeners.

That approach comes with tradeoffs. Brands like WiiM have shown that a comprehensive, frequently updated operating system can win over a large segment of the market, especially when paired with features such as room calibration and broad device compatibility. At this point, support for the major streaming platforms is largely table stakes across the category.
Where these products are ultimately judged is not on spec lists or feature counts, but on how smoothly they operate day to day, whether firmware updates are painless rather than disruptive, and how they actually sound once they are part of a real system. iFi is betting that its focus on noise control, power integrity, and flexible system roles will resonate. Whether that is enough to stand out in a crowded sub-$1,000 field will be up to listeners to decide.
Chinese robotics leader Unitree took full advantage of the nation’s Lunar New Year celebrations this week to show off the impressive skills of its G1 humanoid robot.
A video (top) of the event shows numerous G1 robots participating in what Unitree described as “the world’s first fully autonomous humanoid kung fu performance.” There’s a spot of breakdancing in there, too.
Performing alongside kids from the Tagou Martial Arts School for the Spring Festival Gala on China Central TV, the robots displayed incredible agility and coordination, moving at around 3 meters per second while performing flips, table vaults, somersaults, and rapid formation changes, blending martial arts with robotics innovation.
The robots were recently upgraded with improved, more dexterous hands, which during this week’s performance supported rapid switching and stable gripping of martial arts props such as nunchaku, Global Times reported.

Unitree founder and CEO Wang Xingxing said the robots executed many of their moves while running at high speed, claiming it as a first for high-dynamic, highly coordinated cluster-control technology.
Wang described the innovations as “very practical” and said they will “facilitate large-scale group deployment of robots in the future.”
The 132-centimeter-tall G1 robot was unveiled in May 2024 and made available three months later for $16,000. The bipedal bot is targeted for research, education, entertainment, and light industrial applications, with researchers, students, and developers encouraged to program and customize the the robot for different tasks.
Unitree also has a full-size humanoid robot called H1, which is about 180 centimeters tall. The H1 is more robust and powerful and is aimed at industrial deployment, while the more compact G1 prioritizes agility and affordability, and is geared more toward research and entertainment.

Airbnb is incentivizing people to open up their homes this summer to FIFA World Cup visitors, offering $750 to new hosts in Seattle and other cities hosting soccer matches.
The short-term rental platform says millions of fans are expected to attend the tournament across 16 cities in the U.S., Mexico and Canada, June 11 – July 19. Officials expect an estimated 750,000 people to visit Seattle during that period, and Airbnb says its hosts will welcome 23,000 guests in the city.
Airbnb says Seattle hosts could earn roughly $3,800 by renting space during the tournament. Searches for Airbnb accommodations in host cities have jumped by an average of 80% compared to the same period last year, the company said Wednesday.
A new host sign-up page provides details about how to publish a listing and terms related to reservations. Eligible zip codes in Seattle are also listed.
Airbnb is also hosting a workshop in Seattle on Thursday for interested property hosts. The afternoon event at RailSpur in Pioneer Square (419 Occidental Ave. S.) will include strategies to boost visibility and secure bookings during the FIFA World Cup; best practices in pricing, calendar management, and guest communication; tips on catering to international fans; insights from Airbnb managers; and networking with fellow Seattle hosts.

Visit Seattle projects nearly $1 billion will be generated for King County over the six matches played at Seattle’s Lumen Field between June and July. The projection includes more than $100 million in direct state and local tax revenue and the creation of more than 20,000 full-time and part-time jobs.
A bill to tax short-term rentals returned to the Washington State Legislature this session and failed to advance again. The legislation sought to allow counties, cities and towns to impose a tax of up to 4% on short-term rentals used by vacation guests on platforms such as Airbnb and Vrbo. The bill also failed to advance during the 2025 session.
Etsy is selling Depop, a secondhand clothing app popular with Gen Z and millennials, to eBay for $1.2 billion in cash, the company announced on Wednesday. Etsy says the deal will allow it to focus on its own marketplace.
Founded in 2011, Depop generated approximately $1 billion in gross merchandise sales — the total value of goods sold through its platform — in 2025. In the U.S., the company saw nearly 60% year-over-year growth. As of December 31, 2025, the marketplace had seven million active buyers, nearly 90% of whom were under 34, and more than three million active sellers.
“Depop has built a trusted, social-forward marketplace with strong momentum in the pre-loved fashion category, and we are confident that as part of eBay, Depop will be even more well-positioned for long-term growth, benefiting from our scale, complementary offerings, and operational capabilities,” said eBay CEO Jamie Iannone in the press release.
