Quad Elite QSP Power Amplifier

The Elite QSP – which stands for Quad Stereo Power – replaces the much acclaimed 909 power amp in Quadʼs range, building upon its predecessorʼs 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 Elite QSP, and the 909 before it, is Quadʼs proprietary Current Dumping technology – originally devised in the 1970s by Quadʼs 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 Queenʼs Award for Technical Achievement, and has since been refined and modernised in successive amplifiers culminating in the Elite QSP.
