Still one of the most popular models in the history of one of the world’s most poignant Hi-Fi brands, the QUAD 33 preamplifier and 303 power amplifier are benchmarks in almost every angle of desirable audio equipment – performance, reliability, industrial design, value and musical romance.
The outstanding performance of the QUAD 303 is still celebrated to this day, and is largely due to the unique output circuit developed by QUAD.
In reissuing the QUAD 303 power amplifier concept, exactly like the matching 33 preamplifer, QUAD’s incomparably experienced service team was matched with the equally adept engineering team to reinvoke the design, romance and performance in a thoroughly modern iteration of a hi-fi legend.
As with the new QUAD 33, every aspect of design and performance has been analyzed and re-engineered way beyond simply modernizing components and refreshing of specifications.
The QUAD 303 power amplifier was intended for normal domestic use with moderately efficient loudspeakers, but it was also used by broadcasting and recording studios worldwide, who appreciated its excellent performance and dependability.
The ethos hasn’t deviated. The original 33 and its partnering 303 were awarded with a ‘Council of Industrial Design Award in 1969’. Even today, the original design is celebrated and confirmed by its presence at the Museum of Modern Art in New York. The new 33 and 303 have been industrially engineered to surpass those original standards, with a truly modern appearance and functionality.
