Quad QSP power amp


The Quad Elite QSP power amplifier replaced the much acclaimed 909 stereo power amp in Quad’s range, building upon its predecessor’s blueprint with upgraded internal components and innovative new circuitry to deliver an even higher level of audio performance.

A key part of the design of the Quad Elite QSP power amplifier, and the 909 before it, is Quad’s proprietary Current Dumping technology – originally devised in the 1970s by Quad’s founder Peter Walker and still one of the few truly innovative amplifier topologies. It was first introduced in the seminal Quad 405, earning that amp both a Design Council Award and The Queen’s Award for Technical Achievement, and has since been refined and modernised in successive amplifiers culminating in the Quad Elite QSP power amplifier.
