Quad Platina Integrated (Black) Amplifier

Power by Design

The engine of the flagship series, the PLATINA INTEGRATED boasts a massive new power amplifier section, setting out its stall as a powerhouse of precision. A ‘dual mono’ class AB design offers 2 x 200W into 8 ohms (300W into 4 ohms) and delivers effortless authority with vast headroom and dynamic control. Engineered to drive even the most demanding loudspeakers, it combines muscular output with audiophile finesse, resolving the finest musical details with scale, grip, and composure.

The amplifier’s design leverages extensive SMD component integration to achieve a compact, low impedance, noise immune design with thermal stability and added manufacturing efficiency.

These sophisticated and short connection lines mean lower parasitic inductance and resistance, which translates to lower impedance in signal and power paths, reduced susceptibility to noise and oscillations, and improved high-frequency performance and stability. Optimised component placement also brings minimal loop areas (important for current paths), reducing electromagnetic interference, and better thermal and electrical symmetry, which is key for audio fidelity and long-term reliability.

Digital Domain

A fully-fledged and truly modern amplifier solution; at the heart of the PLATINA INTEGRATED digital capabilities lies a state-of-the-art DAC featuring an ES 9038 PRO chip. A hallmark of high-end DAC design, the DAC section uses two high-precision master clocks, one for 44.1 kHz and one for 48 kHz families. Capitalising on QUAD’s rich history in analogue and digital audio solutions, this DAC chip implementation ensures astonishingly-low jitter levels with improved transparency and imaging for faithful reproduction of digital source material – source materials that can extend into PCM up to 768 kHz and DSD512, allowing for lifelike detail across a wide range of audio formats. Utilising the full strengths of the ES 9038 Pro, the PLATINA INTEGRATED also offers listeners the ability to upsample lower-resolution PCM streams to either 352.8kHz or 384kHz, unlocking greater detail and smoothness from compressed or legacy recordings. A choice of five user-selectable DAC reconstruction filter settings, allows subtle yet effective tailoring of the sound character to suit both the source material and listener preference. This level of fine-tuning is particularly valuable when navigating the variable quality often encountered across digital formats and streaming platforms.

Usability

Despite its wealth of performance options and capabilities, like all PLATINA components, the QUAD PLATINA INTEGRATED is built around an expertly crafted general user interface (GUI), tactile controls and a full colour TFT display. This interface improves functionality by making complex settings and features more accessible and intuitive. It allows users to navigate options quickly, view system status at a glance, and adjust parameters with clarity and precision, without needing to remember commands or rely on cryptic button combinations.

Analogue Domain

The QUAD PLATINA INTEGRATED can accommodate analogue sources via two pairs of RCA inputs, a pair of balanced XLR inputs, and a dedicated, high-performance MM/MC phono stage. Each analogue input can be selected via the remote control, and each offers independent input sensitivity via the extensive GUI.

Via the aforementioned GUI, the phono stage’s three selectable gains (46dB, 52dB, 60dB) and selectable input impedance (MM or MC) can be accessed and adjusted to suit the user’s requirements. This custom-designed phono stage is QUAD’s most advanced phono stage yet. This JFET design enhances the MM/MC functionality by providing a high input impedance, making it ideal for seamless interfacing with MM (moving magnet) and MC (moving coil) cartridges. Its exceptionally low noise performance is particularly advantageous for MC cartridges, which typically produce very small output signals in the millivolt or microvolt range.

The Conclusion

A result of many thousands of man-hours devoted to concept, design, and engineering, the PLATINA series stands as a testament not only to the tradition of QUAD electronics, proven benchmarks, and brand philosophies; it is, without a doubt, the most advanced and accomplished QUAD solution to date.
