Arcam A15+ Integrated Amplifier The A15+ is Arcam's answer to a specific question: what happens when you take the Radia A15 — already a well-regarded amplifier — and ask the engineering team to go further? The result is an amplifier with an enhanced power supply, current-generation wireless capabilities, and a DAC stage built around the ESS ES9018. It is compact, it is well built, and it is designed to handle everything from a turntable to a television from a single chassis. Class AB Amplification The A15+ uses Class AB amplification — a proven topology that Arcam have refined over nearly 50 years of amplifier design, dating back to the A&R Cambridge A60 of 1976. Two channels driven, 20Hz–20kHz into 8Ω: 80W per channel. Into 4Ω at 1kHz: 120W per channel. Harmonic distortion at 80% power into 8Ω at 1kHz: 0.002%. The cabinet is aluminium throughout — front, top, sides and rear panels — with solid aluminium dials. At 431 × 344 × 98mm and 10kg, it sits naturally on a shelf or in a rack without demanding special treatment. The DAC — ESS ES9018 The digital section is built around the ESS ES9018 high-resolution DAC. Supported sample rates are 192, 176.4, 96, 88.2, 48, and 44.1kHz, at bit depths of 24 and 16. Digital frequency response is 20Hz–20kHz ±0.2dB, with a signal-to-noise ratio of 109dB (A-weighted, ref. 50W, 0dBFS). The HDMI eARC input is included — a practical addition that allows a television to connect directly to the A15+ without a separate DAC or additional cabling. Phono Stage The phono stage is MM, with an input impedance of 47kΩ + 100pF and a frequency response tracking the RIAA curve to within ±1dB across 20Hz–20kHz. Arcam describe it as meticulously tuned — a claim worth taking at face value from a manufacturer whose phono stages have consistently been among the better implementations at this price point. Wireless — Snapdragon Sound and Auracast Bluetooth is version 5.4. Snapdragon Sound is included — Qualcomm's end-to-end audio platform, delivering uncompressed digital audio over Bluetooth when both devices support it. This is a meaningful distinction from the standard lossy Bluetooth connections that most products at this level offer. Auracast is also built in: Bluetooth's broadcast audio standard, which allows the A15+ to share audio to multiple compatible headphones or speakers simultaneously, without conventional pairing. Supported codecs include AAC and LE Audio. Headphone Output A headphone output is provided, with a load range of 16Ω to 2kΩ. Maximum output level into 32Ω is 2.5V RMS; into 300Ω it is 5V RMS — a useful range that covers everything from efficient in-ear monitors to high-impedance over-ear headphones.
