ARCAM Launches New Integrated Amplifiers 'A15+' and 'A5+' with Redesigned Circuitry for Lower Noise and Optimized Components for Enhanced Sound Quality

Harman International Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo; President and CEO: Takuma Kuwabara) will begin sequentially releasing the 'ARCAM A15+' and 'ARCAM A5+' integrated amplifiers from British premium audio brand ARCAM starting June 25, 2026 (Thursday). These models feature redesigned circuitry for lower noise and optimized key components to enhance sound quality.

The 'Radia' series from ARCAM has long upheld the founding philosophy of 'Music First,' combining over 40 years of analog expertise with cutting-edge digital technologies to meet modern demands. This fusion delivers high-fidelity music reproduction worthy of true music lovers' lifestyles. By prioritizing the purity of audio signals and achieving high product completeness, the Radia series has received consistent acclaim since its launch.

The 'A15+' and 'A5+' continue this Radia philosophy while introducing multidimensional improvements to internal circuitry and power supply design to further elevate sound performance. The circuit layout has been redesigned to streamline and optimize signal flow, while key components have been carefully reviewed in terms of application and placement, enhancing the purity of the audio signal. As a result, these models achieve more accurate and natural reproduction in terms of transient response, sound image clarity, and soundstage width.

Additionally, the design incorporates intelligent control of digital circuits, Bluetooth modules, and DAC boards, shutting down unused circuits based on usage conditions. This suppresses noise on the power line, creating a quiet playback environment that faithfully reproduces subtle tonal nuances and spatial depth. Both models support Bluetooth wireless connectivity, enabling convenient wireless listening in addition to speaker playback. With support for Auracast™, audio can be shared simultaneously with compatible devices, while bidirectional Bluetooth functionality allows audio output to wireless headphones. Users can flexibly switch listening modes depending on time or environment.

The 'A15+' offers greater driving power and includes an HDMI eARC input, enabling high-quality playback of both music and video content from a wide range of sources. The 'A5+' condenses the Radia series philosophy into a compact form, delivering the distinctive ARCAM sound quality for everyday listening.
