NEW QUAD 33 / 303 preamplifier / poweramplifier
Very few Hi-Fi components are as instantly recognisable as the QUAD 33 and 303, and for that we make no apologies!
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.By revisiting the QUAD 33 and 303 components, QUAD demonstrates its authenticity, pedigree and excellence as a juggernaut of the British hi-fi world - past and present.
In listing the names involved in the development of this stunning iteration of an icon, you.ll find a calculation of close to 200 years of engineering experience and 100+ years of QUAD-exclusive design and service.
A dream team of Rob Flain & Paul McConville (the world.s most experienced QUAD service engineers), Jan Ertner (30 years of experience in QUAD design), Peter Comeau (the acoustic director behind some of QUAD.s most successful loudspeakers) and David McNeill (the industrial designer responsible for two decades of QUAD innovations) were all a part of this labour of love, making no compromise in the demand for a product that could bear the name of 33 and 303.
The external design is specifically intended to continue the QUAD tradition of practical simplicity. Yet, it would be foolish to ignore the implementation of modern-day capabilities, such as an informative backlit display, delicate LED illumination and remote control functionality. And just like the original, the overall appearance is unmistakably QUAD!
The new QUAD 33 is supported by digital microprocessor control but is otherwise based faithfully on a classic analogue design.
The 33 feeds the loudspeakers via the power amplifier using dedicated stereo pre-outputs with an RCA line-level and balanced XLR pre-out option. There.s also an AUX output for additional versatility and functionality.
Now equipped with fully balanced XLR inputs and outputs, the 33 is set apart from other preamplifiers and even its forefather model.
