QUAD’s reputation as a manufacturer of hi-fi products that deliver musical accuracy through technical prowess is legendary and is nowhere more evident than in the Platinum series of components.


Both the Platinum Stereo and Platinum Mono sport connection terminals of the highest quality, with a choice of balanced XLR and single-ended RCA inputs and rugged, gold-plated speaker terminals to accommodate single-or bi-wiring, according to the users requirements. A 12V trigger is also provided, enabling the amps to power up and down automatically in line with the Platinum DMP. Platinum Series components are designed to work together seamlessly, optimising high-definition signal transfer whilst also ensuring compatibility with a wide range of partnering equipment. The Platinum amps will happily drive any loudspeaker the user chooses from conventional hi-fi loudspeakers to our own ESL series


The Platinum Series is a high-end solid-state component range which is the next step up from the highly acclaimed Elite Series. In many ways, it's classic Quad: simple, solid and classy on the outside and devilishly clever within. Delivering high-fidelity sound in its purest form from every digital source, the Platinum Series is the perfect encapsulation of Quads mission statement: “the closest approach to the original sound”

Whether you choose the Platinum Stereo or a pair of Platinum Monos, the end result is a musical performance of beguiling power and finesse, brimming with dynamic contrast and subtle detail for an exceptionally realistic experience. Neither too warm nor too bright, the Platinum Series delivers the truthful sonic neutrality for which Quad is famed, accurately reproducing the harmonic and dynamic structure of live music and ensuring every musical performance is delivered in its entirety – true to the recording and utterly unrestrained.

Technology: Ultra-Clean Sound

Quad has undertaken extensive research into electromagnetic interference inside amplifiers and both new power amps pay particular attention to the control of crosstalk and the flow of magnetic fields. There are new PCB layouts to screen signal paths, while custom-made transformers protect amplifier boards from magnetic interference and hum induction, contributing to an ultra-clean technical performance with vanishingly low levels of noise and distortion.

Dynamic performance is the key to musical behaviour. In Platinum the musical dynamics are maintained precisely by making sure that each amplification stage is fed by its own power supply. In that way the power rails for the preamplifier and driver circuits avoid modulation by, say, the current demands of the output stage.

Amplifier stages are normally linked by capacitors to take care of DC offsets. Unfortunately capacitors in the signal path degrade the purity of the music signal. In Platinum direct coupling of each stage is enabled by the use of a DC servo – a circuit that compensates for any unwanted DC voltage and removes it without affecting the music signal.

As you would expect every component in the Platinum Series is perfectly matched ensuring ease of use in addition to the advanced sound quality. By investing in Quad Platinum you are assured that the hallmark tradition of Quad engineering since1936 will exceed your requirements for ‘the closest approach to the original sound’

“What’s really deceptive about the Quad combination is that it makes everything it does seem so easy: recordings are opened up and made compelling, and yet require very little effort from the listener”
