Every stage of the Quad Artera Stereo power amplifier has been engineered to deliver power, precision and stability, from the transformer to the input terminals. Rated at 140W per channel into 8 ohms, it provides ample drive for a wide range of loudspeakers, maintaining composure even under demanding dynamic conditions, thanks to QUAD’s patented Current Dumping technology. Carefully optimised balanced XLR inputs further enhance performance, contributing to an exceptional signal-to-noise ratio.

Compact yet highly capable, the Quad Artera Stereo power amplifier features the latest evolution of QUAD’s renowned Current Dumping topology, originally introduced in the iconic QUAD 405—one of the most celebrated amplifier designs in British hi-fi history.

This approach combines the sonic purity of Class A amplification with the efficiency of Class AB. A low-power Class A stage ensures signal accuracy, while a high-power current dumping stage provides the necessary output to control the speakers. These stages are seamlessly integrated via a precision network, delivering a balance of clarity, control and dynamic authority in a compact, cool-running design.

Power output is conservatively specified at 140W per channel into 8 ohms and 250W into 4 ohms, ensuring compatibility with a wide range of loudspeakers, including QUAD’s electrostatic designs. Connectivity includes RCA and balanced XLR inputs, a 12V trigger and high-quality speaker terminals, supporting straightforward integration into high-performance systems.

Elegantly understated on the outside and technically sophisticated within, the Quad Artera Stereo power amplifier continues QUAD’s tradition of innovative amplifier design with a focus on musicality, reliability and engineering integrity.
