JPLAY x HighResAudio

JPLAY has added HighResAudio as its third integrated streaming service alongside TIDAL and Qobuz, further strengthening its position as a playback application focused on high-quality audio and multi-source library management within a single interface. The new partner service specialises in studio-quality hi-resolution recordings, offering lossless streaming up to 24-bit/192 kHz together with access to a virtual storage space for purchased music. This combination may be particularly appealing to listeners who treat high-resolution files as a primary listening format rather than simply an extension of conventional streaming. Integration with HighResAudio is already available in the latest version of the JPLAY app. After signing in to a HighResAudio account from within JPLAY, users gain access to the platform's full streaming catalogue and can browse it in the same unified environment used for other supported services.

Questyle Sigma & Sigma Pro

Questyle is expanding its range of portable audio devices with two new models, Sigma and Sigma Pro. The company positions them as mobile solutions intended to deliver a level of performance closer to full-size desktop systems, aimed at users who want genuine high-fidelity playback from a computer, smartphone or tablet. Both devices are built around Questyle's proprietary Current Mode Amplification, or CMA, technology, which is designed to combine very low distortion, strong dynamic performance and substantial output power within a compact form factor.

Astell&Kern A&ultima SP4000 Copper

Astell&Kern is one of the most recognisable brands in the high-resolution portable player segment. The company built its reputation on advanced Android-based digital audio players designed to combine high sound quality with support for streaming services and a distinctive angular industrial design. The A&ultima line serves as the manufacturer's flagship series, where its most sophisticated technical solutions typically make their debut, including complex DAC configurations, elaborate headphone amplification stages and proprietary technologies intended to improve signal processing and reduce noise. Limited editions of these players have long attracted particular attention, and because copper is a material that carries strong positive associations in the hi-fi world, the standard A&ultima SP4000 is now joined by a special A&ultima SP4000 Copper version. According to the manufacturer, copper has been used not only for visual impact but also as a component intended to influence the sonic character directly. The new model is aimed at listeners who treat a portable player as a fully fledged high-end source in any listening environment.

Fezz Audio Luna

When Fezz Audio, then a small, unknown domestic manufacturer, unveiled its first amplifier ten years ago, very few people believed it stood a chance. Yes, the company was connected to a respected producer of transformers used by prestigious audio brands, but as its own label it simply did not exist in the consciousness of audiophiles. At launch, Fezz brought only a single product to market. It was not a compact digital-to-analog converter, not a lavishly equipped solid-state integrated, but a modest tube integrated that, from the customer's perspective, distinguished itself mainly with its reasonable price and a handful of available color finishes. How was this oddity ever supposed to shake up the tightly sealed hi-fi world? And yet, within just a few months, Silver Luna was on everyone's lips. Reviewers and music lovers quickly took to it, drawn by its honest, fully tube-based sound and its raw, minimalist, slightly industrial styling. It was a straightforward, sensible piece of gear with no gimmicks, no cosmetic frills, no wooden ornaments - just engineering focused on doing one job well. It turned out you really could build tube amplifiers in Europe that didn't cost as much as a new car.

Erik Wiederholtz - Perlisten

Perlisten entered the hi-fi market in a way that surprised many - suddenly, yet with clear ambition. Its debut was far from accidental, led by seasoned engineers and managers with decades of experience in transducers, measurement systems, and loudspeaker design. Co-founder and president Dan Roemer brings over 25 years of industry expertise, including work with the NHT research group, MITek Corporation, and projects in the automotive and aerospace sectors. Lars Johansen, with more than 30 years in audio, has contributed to brands like JBL, Harman Kardon, Klipsch, and Jamo, and later served as partner and president of Miller & Kreisel, supplying solutions for recording studios and premium home theatres. Since its formal launch in 2016, Perlisten has aimed to deliver top-tier products, reflected in its pricing. The introduction of the more accessible A-Series marked a shift, opening the brand to a wider audience. Interest continues to grow, yet many enthusiasts remain unaware of the company's origins, the people behind it, and its long-term objectives. This is why I decided to speak with someone who has been with Perlisten from the start and understands every stage of its development - from early concepts and factory selection to launches and subsequent product lines. Erik Wiederholtz, Perlisten's Technical Director, is an acoustics specialist with experience in transducer modelling, dynamic speakers, MEMS digital microphones, hearing aids, headphones, and small speakers. Our conversation, I believe, will shed light on the company's foundations and help readers understand what Perlisten represents.

Melodika SBP

Melodika expands its Sky Blue range with a new power cable, the SBP, designed for users who value clean, stable power delivery in audio and video systems. As the company explains, high-quality power supply is often a crucial yet underestimated element influencing the final sound performance. The SBP has therefore been engineered as a solid, technically sound solution for demanding hi-fi enthusiasts seeking to minimise electrical interference and ensure long-term reliability.

Melodika is a Polish manufacturer of cables and hi-fi loudspeakers, established in 2010. The company follows a pragmatic, no-nonsense design philosophy focused on real engineering and audible results rather than marketing gimmicks. Its product portfolio includes speaker, signal and power cables, as well as installation wiring and accessories, all developed and assembled in Poland. Melodika's mission is to deliver high-quality sound at reasonable prices - a goal consistently recognised by numerous awards and positive reviews from both Polish and international audio experts.

At its core, the SBP uses three 2.5 mm² conductors made from high-purity, oxygen-free copper (OFC) of 4N grade (99.99 % purity). This material guarantees excellent conductivity, low resistance (around 7.75 Ω/km) and minimal oxidation over time. The cable features a double-shielded design - an 85 % coverage OFC braid combined with a Mylar foil - effectively suppressing electromagnetic and radio-frequency interference from neighbouring devices or cables. This makes the SBP suitable not only for advanced home hi-fi systems but also for professional or industrial environments where power stability and noise suppression are critical.

To ensure durability and safety, the SBP incorporates a triple-layer insulation system. Its inner dielectric layers provide a high insulation resistance of over 200 MΩ/km, while the outer jacket, made of modified PVC, offers enhanced mechanical, thermal and chemical protection. Such construction allows for flexible use, including in-wall installations and demanding operating conditions. New, gold-plated connectors further improve contact stability and corrosion resistance, ensuring a secure connection and long-term performance. The cable has successfully passed a 4000 V voltage test, confirming its robust insulation and high safety margin.

Melodika offers the SBP in eight lengths ranging from 0.5 m to 5 m, priced between €132 and €239. Each version comes with a 5-year manufacturer's warranty. Thanks to its solid construction, wide compatibility and noise-reducing properties, the SBP can be used not only in audio and home cinema systems but also in measurement, laboratory or medical equipment where clean and stable power is essential.

Songs Without Singers - How Algorithms Replaced the Artists

In 1997, Radiohead released their album OK Computer. It was a record that not only startled the band's loyal followers but also anyone who happened to hear it. It explored themes of technology, alienation, and social unrest in a rapidly shifting world, and it's often read as a darkly prophetic commentary on the dehumanizing influence of the digital age - a message that, almost thirty years later, still feels unnervingly precise. The lyrics, often delivered in a weary, detached voice, paint a grim, inevitable future where people lose themselves in virtual realities. They trace the moment when tools meant to serve us quietly begin to own us, turning convenience into dependence. The album became legendary for its unorthodox production and haunting, atmospheric sound, both of which heightened its sense of unease and disorientation.

Hegel H150

Hegel has announced the launch of the H150 streaming amplifier - an all-in-one hi-fi solution designed to combine versatility, musical refinement and ease of use in a compact, elegantly built chassis. Positioned as the successor to the H120, the H150 bridges the gap between affordability and audiophile performance, offering much of the same technology found in Hegel's flagship models, including the company's advanced streaming platform, app control and patented SoundEngine 2 amplification. Nicknamed 'The Prodigy', the H150 embodies Hegel's philosophy that true excellence should be accessible. While sitting at the entry point of the Norwegian manufacturer's integrated range, it demonstrates the sonic maturity and control more often associated with far costlier components. Delivering 2 x 75 watts into 8 ohms, it is capable of driving demanding loudspeakers with confidence, combining precision, scale and authority that far exceed expectations for its size and price.

Lyngdorf TDAI-2210

Lyngdorf Audio has announced the launch of its latest digital streaming amplifier, the TDAI-2210 - a model that bridges the gap between the compact TDAI-1120 and the flagship TDAI-3400, offering a balance of versatility, performance and refinement. The new amplifier features an elegant colour touchscreen interface, next-generation digital amplification, and the company's acclaimed RoomPerfect room calibration technology. The TDAI-2210 represents Lyngdorf's continuing evolution of digital amplification design. With multiple digital inputs, including USB-C and HDMI 2.1, analogue connections, optional modular expansion, and integrated music streaming, the amplifier is engineered to adapt to any system configuration. Delivering 2 x 210 watts into 4 ohms, it has the power and control to drive even the most demanding loudspeakers with ease.

Monitor Audio Silver 7G

Monitor Audio has announced two new limited-edition loudspeakers based on its Silver Series 7G range - the Silver 300 7G Limited Edition and the Silver 100 7G Limited Edition. Both models are presented in a new Carbon Black Metallic finish and individually numbered, combining subtle design updates with proven acoustic engineering. The Silver Series 7G platform, introduced in 2021, sits at the heart of Monitor Audio's mid-range catalogue, bridging the gap between the Bronze and Gold lines. It introduced several key innovations, including Rigid Surface Technology II (RST II) and a new generation of Ceramic-Coated Aluminium Magnesium (C-CAM) drivers. These limited-edition versions keep that same foundation while refining both aesthetics and detail to mark the series' ongoing success.
