This model featured prominently in many of our magazine advertisements and helped establish our reputation in British hi-fi. Since then, Arcam has produced many highly regarded amplifiers. The Arcam A15 continued that legacy with great success, earning a reputation for performance and reliability. Naturally, expectations are high for its successor, the Arcam A15+, which is set to carry the torch forward.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eWireless audio with Bluetooth 5.4,\u003c\/li\u003e\n\u003cli\u003eFeaturing Snapdragon Sound for wireless lossless audio,\u003c\/li\u003e\n\u003cli\u003eFeaturing Auracast for connecting wireless headphones or speakers to play music in multiple spaces\u003c\/li\u003e\n\u003cli\u003eHDMI eARC input\u003c\/li\u003e\n\u003cli\u003eHi-res audio ESS ES9018 DAC\u003c\/li\u003e\n\u003cli\u003eMeticulously tuned phono stage\u003c\/li\u003e\n\u003cli\u003eClass AB amplification\u003c\/li\u003e\n\u003cli\u003e2x 80 Watts (8Ω) power output\u003c\/li\u003e\n\u003cli\u003eCompact remote control\u003c\/li\u003e\n\u003cli\u003eSolid aluminium dials\u003c\/li\u003e\n\u003cli\u003eAluminium front, top, sides and rear panels\u003c\/li\u003e\n\u003cli\u003ePlastic free packaging\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSignature Arcam Sound, With More Power\u003c\/h3\u003e\n\u003cp\u003eLike the more affordable A5, the A15+ retains Arcam’s signature full-bodied, smooth sound — but with added power.
