A British Amplifier Fifty Years in the Refining
The “A” in ARCAM has always stood for amplification. From the moment the A&R Cambridge A60 appeared in 1976, the company built a reputation on amplifiers that placed musical truth above spectacle — an approach that has carried ARCAM through five decades of continuous engineering in Cambridge, England. The ARCAM A25+ arrives as the most accomplished expression of that lineage within the Radia+ range: an integrated amplifier that takes the award-winning ARCAM A25 as a starting point and refines the power supply, digital conversion and wireless capability well beyond the original brief. The result is the best-sounding and most versatile integrated amplifier ARCAM currently builds, and a fitting anniversary statement from one of British audio’s founding names.
Fifth-Generation Class G Amplification
Where most rivals settle for conventional Class AB or the ubiquity of Class D, ARCAM has spent decades perfecting Class G — a topology that runs in pure, low-level operation for the majority of listening, then summons additional power rails the instant the music demands them. The ARCAM A25+ carries the fifth generation of this design, delivering 100 watts per channel with the ease and headroom of a far larger amplifier. Orchestral climaxes arrive without strain; quiet passages retain their delicacy and air. The Class G approach also runs cooler and more efficiently than tradition allows, which suits an amplifier intended to serve as the long-term centre of a serious two-channel system.
Every Source, From Vinyl to Television
An integrated amplifier earns a place in the modern home by welcoming everything the household plays. The ARCAM A25+ answers with a meticulously tuned moving magnet phono stage that lets a turntable speak with proper body and detail, alongside three analogue line inputs for existing separates. On the digital side, an ESS Sabre DAC — newly specified for the Plus generation — handles conversion with genuine hi-res authority, fed by coaxial, optical and USB-C connections. HDMI eARC deserves particular mention: connect a television directly and film soundtracks gain the scale and articulation that soundbars simply cannot reach. From a cherished record collection to an evening’s viewing, one amplifier holds the entire system together.
Wireless Listening Without Compromise
Few products in this class treat wireless audio as seriously as the ARCAM A25+. Bluetooth 5.4 arrives with Snapdragon Sound on board the specification sheet in name and in practice — lossless digital audio transmitted without cables, so a phone or tablet becomes a genuinely high-fidelity source rather than a convenience compromise. Auracast extends the idea further, broadcasting to multiple compatible wireless headphones or speakers at once so music can follow the household from room to room, no pairing rituals required. For anyone seeking a stereo amplifier with Bluetooth that concedes nothing to sound quality — or a hi-fi amplifier with Bluetooth flexible enough to transmit as well as receive — the ARCAM A25+ makes the strongest case in the Radia+ range.
Solid Aluminium, Built to Remain
British restraint defines the presentation. Aluminium panels dress the front, top, sides and rear of the chassis, while solid machined aluminium dials turn with the weighted precision that only proper metalwork provides. A dedicated headphone output invites late-night sessions with wired or wireless headphones alike, and the compact remote control keeps daily use effortless. Even the packaging reflects the same conscience: entirely plastic-free, designed for simple, natural disposal. This is an amplifier conceived to be owned for decades, not upgraded away in a product cycle.
Audition the ARCAM A25+ at Audio Lounge
Specifications describe the ARCAM Radia A25 successor; only listening explains the appeal. Audio Lounge invites you to hear the ARCAM A25+ in our Wigmore Street demonstration rooms in the heart of London, partnered with loudspeakers and sources matched to your own ambitions for the system. Our team can advise on turntable pairing for the phono stage, television integration through HDMI eARC, and the wireless possibilities Auracast opens across the home. Contact us to arrange a private audition of the ARCAM A25 Plus generation, and discover why nearly fifty years of Cambridge engineering still sets the standard for the British integrated amplifier.
About ARCAM
ARCAM began in 1976 when two Cambridge University engineering students built the A&R Cambridge A60, an integrated amplifier that would sell in the tens of thousands and establish a distinctly British voice in high-fidelity audio. Five decades on, ARCAM remains devoted to the same principle: engineering in service of music, never fashion. Now part of the Harman family, the company designs from Cambridge, England, where amplification remains the discipline closest to the ARCAM name — the “A” has never stood for anything else. From the pioneering use of Class G topology to today’s Radia+ range, ARCAM continues to define what a British amplifier should be. Explore the full ARCAM collection at Audio Lounge.
