Power supplies are rarely the most exciting part of a hi-fi system. Nobody invites friends over to admire a particularly impressive wall adapter, and even the most enthusiastic audiophiles probably spend more time discussing DAC chips, amplifier topologies, and speaker cables than the electronics responsible for keeping everything running. Yet power supplies have become an increasingly important topic as our systems have filled up with streamers, network switches, reclockers, digital transports, and other compact devices. Many rely on external DC adapters, which makes them relatively easy to replace without modifying the equipment itself. The usual upgrade path involves swapping the manufacturer's switching adapter for a heavier, more expensive linear power supply. NuPrime, however, has decided to approach the problem from a different direction. Its new SiGa Power75 combines silicon carbide and gallium nitride semiconductors with an active noise cancellation circuit, offering six regulated DC outputs for compatible audio and digital equipment. It promises the low-noise characteristics enthusiasts typically associate with sophisticated linear supplies, but achieves them through a rather different set of technologies.

Not every gaming headset needs a wireless transmitter, a rechargeable battery, or a collection of features that require half an hour of configuration before you can start playing. Sometimes, a good pair of headphones, a decent microphone, and a cable are all you really need. That's the idea behind the JBL Quantum 120, a new entry-level gaming headset that brings some of the technology found in the company's more expensive models to a much more affordable package. Rather than competing with sophisticated wireless designs, JBL has kept things relatively simple, combining a conventional 3.5 mm connection with large 50 mm dynamic drivers, a detachable microphone, and support for its Quantum Spatial Sound processing and QuantumENGINE software. The result is a headset aimed at gamers who want solid performance and useful features without paying extra for wireless connectivity they might not actually need.

Victrola is preparing to bring one of its more unusual recent products to Europe. First shown at CES 2026, Soundstage is neither a conventional pair of speakers nor an all-in-one record player. Instead, it is a low-profile soundbase designed to sit directly underneath a turntable and provide room-filling sound without introducing the vibration problems that normally make such an arrangement a bad idea. The concept is aimed squarely at listeners who want a compact vinyl system without separate speakers, an amplifier and the extra furniture that usually comes with them. Following its US launch, Soundstage is now heading to Europe, where sales are scheduled to begin in October.

While much of the high-end IEM market seems determined to fit ever more drivers and technologies into increasingly elaborate shells, Noble Audio has decided to move in the opposite direction. Iris is a new universal in-ear monitor built around a single 10.2 mm dynamic driver, with the entire acoustic architecture developed to make that one transducer cover the full frequency range as coherently as possible. It is an interesting change of pace for a company whose catalog contains plenty of ambitious multi-driver designs, and Noble makes the philosophy unusually clear - one driver, one vision. Rather than competing through sheer driver count, Iris focuses on simplicity, consistency and the particular qualities that have kept single dynamic driver earphones relevant despite increasingly complex alternatives.

Dan Clark Audio's Aeon family has occupied an important place in the company's lineup since 2017, offering much of the engineering associated with its more ambitious planar magnetic headphones in a smaller and more accessible package. Aeon Core now takes over that role from Aeon 2, but this is more than a cosmetic refresh. The new closed-back model introduces a completely redesigned planar magnetic driver, revised tuning based on updated psychoacoustic research and a new aluminum-and-wood finish, while retaining the distinctive shape and comfort that have become trademarks of the series. Dan Clark Audio also makes an unusually bold claim for the new model - Aeon Core is intended to preserve the isolation and practicality of a closed headphone while avoiding the confined, bass-heavy presentation often associated with the format. Dan Clark Audio officially positions Aeon Core as the direct successor to Aeon 2 and the new entry point to its planar magnetic range.

AudioQuest DragonFly is one of those products that hardly needs an introduction. The original model appeared in 2012 and helped turn the USB dongle DAC from a niche computer-audio accessory into a genuinely mainstream hi-fi product, with more than 300,000 DragonFlys sold worldwide since then. Black and Red followed in 2016, Cobalt arrived three years later, and then the series went quiet for almost seven years. Copper finally breaks that silence. Rather than simply updating Cobalt with a different finish, AudioQuest has substantially reworked the internal architecture, giving its latest DAC-preamp-headphone amplifier more output power, lower current consumption and a new copper-plated enclosure intended to improve RF noise dissipation.

At the same time that Noble Audio is stripping the formula back to a single dynamic driver with Iris, the company is taking a very different route at the more accessible end of its wired IEM range. Vanguard builds on the success of Knight, which Noble describes as the highest-selling IEM in its history, but replaces that model's dynamic, balanced-armature and piezoelectric combination with a new three-way hybrid architecture based around one dynamic driver and two custom balanced armatures. The idea is not simply to add another entry-level model to an already crowded category, but to create a more refined starting point for listeners who want the Noble sound without immediately moving into the company's considerably more expensive universal monitors.

Marantz has introduced the second generation of its Cinema Series AV receivers. The new family consists of the Cinema 50 Series 2, Cinema 60 DAB Series 2 and slimline Cinema 70s Series 2. The company has not opted for a major visual overhaul, as the distinctive styling of the current range has proved to be one of its strongest features. Instead, the most important changes have been made inside the receivers and within their software. Marantz promises improved sound quality, wider access to Dirac Live room correction, new installation tools, expanded streaming capabilities and additional features designed for modern gaming PCs and consoles.

Klipsch is celebrating its 80th anniversary with a major overhaul of one of the most recognizable parts of its powered-speaker lineup. The Fives II, The Sevens II and The Nines II retain the familiar three-step hierarchy of the previous generation, but little else has simply been carried over. All three models combine Klipsch's horn-loaded acoustic design with a completely new electronics platform developed by Onkyo engineers in Osaka, while adding built-in network streaming, HDMI 2.1, Dolby Atmos and a much broader range of system functions. The new generation was first shown at CES 2026 and has since reached stores in the US, UK and Europe.

Marantz is refreshing the entry point to its traditional hi-fi range with two full-size components - the Model 70 integrated amplifier and the matching CD 70 player. The new duo follows in the footsteps of the popular PM6007 and CD6007, but the transition involves considerably more than a change of model numbers. Both products adopt the visual language previously associated with more expensive Marantz components, while the amplifier gains HDMI ARC, two-way Bluetooth connectivity and a revised amplification section. The CD player, meanwhile, combines conventional disc playback with high-resolution files from USB storage.
