ONE FOR THE HISTORY BOOKS
Very few Hi-Fi components are as instantly recognisable as the QUAD 33 and 303, and for that we make no apologies!

QUAD 33 PREAMPLIFIER
Quad 33 preamplifier features a high performance, low noise MM/MC phono stage, a dedicated headphone amplifier, 3 x RCA and 1 x XLR inputs, XLR out, and Quad’s iconic ’Tilt’ adjustment, all within an iconic chassis that’s home to physical tone controls, input selections, and a delicate LED backlit display.
Still one of the most popular models in the history of one of the world’s most poignant Hi-Fi brands, the QUAD 33 and 303 are benchmarks in almost every angle of desirable audio equipment – performance, reliability, industrial design, value and musical romance.

QUAD 33 DREAM TEAM
- Peter Comeau: famed acoustic director for Quad, Wharfedale, Mission & Leak.
- Rob Flain & Paul McConville: world’s most experienced Quad service engineers.
- Jan Ertner: 30yrs of Quad acoustic design.
- David McNeil: 20yrs of Quad industrial design.

Sure, the USA had Jordan, Pippin, Johnson, Bird, and Barkley. But over 200 years of combined experience have donned Quad’s iconic jersey numbers 33 & 303, taking to the court to produce a once in a generation moment of magic.

ISOLATION = INTEGRITY
Vastly superior internal components. Greater chassis real estate to improve circuitry architecture (topology). Complete isolation from power supply/high-power circuitry noises. It’s these elements that combine to give you near perfect soundstage, imaging, detail and dynamics. And it’s Quad 33 that perfectly combines these elements.

RETRO SOUL... MODERN CONTROL
A custom-tooled anodised fascia with accented rotary dials that gently shift hue in the light is paired with a motorised ALPS volume control that independently rotates with remote adjustments, a subtle touch of sophistication. With backlit LCD display and input selectors in Quad’s iconic orange, Quad 33 wonderfully balances both contemporary and classic.

TWEAK LIKE A PRO WITH TILT CONTROL
Avoid thin, bright or bloated tonal adjustment with Tilt Control, a tonal attenuation design that tilts the audible frequency range (on a 700Hz axis), subtly adjusting the overall sound balance with ‘warm’ or ‘cool’ hints, and all without altering volume or colouring your sound.

NO NOTES LOST IN TRANSLATION
HiFi separates is a game of whispers. But balanced XLR cables eliminate signal interference, leaving the original audio signal untouched. And Quad 33 is now equipped with fully balanced XLR inputs and outputs, ensuring the integrity of your audio throughout the system chain.

VINYL: THE PEOPLE'S CHOICE
Double digit sales growth. 81 million units sold globally. $800 million in sales in the U.S. alone. Our love for vinyl is stronger than ever. That’s why Quad 33 includes a purpose built MM and MC phono preamplifier for exquisite vinyl playback.
