QUAD 303 Stereo power amplifier

The Quad 303 stereo power amplifier has been an iconic part of the hi-fi world since its original release, earning worldwide acclaim from home users as well as broadcast and recording studios. Initially designed for home use, it quickly gained cult status in professional audio environments, where its outstanding performance and exceptional reliability were highly valued. The latest version continues this tradition impressively, meeting the modern demands of discerning audiophiles. With careful updates in technology and design, the Quad 303 remains true to its roots while surpassing modern sound standards.
 

High fidelity sound through innovative circuitry
The remarkable sound quality of the Quad 303 is the result of the legendary "symmetrical triple circuit," an innovative technique developed by Quad to optimize music reproduction. This unique circuit ensures a fully symmetrical output stage, minimizing distortion to an almost inaudible level while providing exceptional stability. Even under high loads, the amplifier remains sonically precise and distortion-free. The new version of the Quad 303 now uses a fully complementary output stage, achieving higher linearity and stability, even during intensive use and high power demands. With 50 W output at 8 Ohms (or 70 W at 4 Ohms), the amplifier effortlessly drives demanding speakers. In bridged mode, the Quad 303 delivers up to 140 W at 8 Ohms or 170 W at 4 Ohms, making it the optimal mono power amplifier for high-performance setups, including Quad's own electrostatic speakers.

Noise-free, stable operation through a powerful transformer
The Quad 303 is not only sonically impressive but also technically designed for noise-free and stable operation. A specially designed 200VA toroidal transformer ensures particularly quiet operation and maintains amplifier stability even under the highest demands. The transformer operates almost silently, supporting pure and unaltered sound reproduction. By using modern power transistors offering exceptional linearity and an extended dynamic range, the Quad 303 reproduces every fine detail of the input signal with clarity and precision. Even under extreme conditions, such as short-circuited or disconnected speakers, the amplifier's sound quality remains stable—a technical achievement that few amplifiers can offer.

Timeless design for maximum stability and exclusive aesthetics
Aesthetically, the Quad 303 remains true to its timeless industrial design, seamlessly integrating into high-quality audio environments. The robust construction with an anodized aluminum case not only provides an elegant appearance but also protects against external interference and vibrations. The CNC-machined heat sinks on the sides are not only a stylish design element but also contribute significantly to heat dissipation, ensuring reliable and long-lasting operation. The Quad 303 combines the best of traditional industrial design and modern technology, with premium materials and craftsmanship meeting the highest standards for years to come.

A masterful reissue of an audiophile hi-fi classic
The new Quad 303 is a thoughtful, masterful reissue of an iconic hi-fi amplifier, building on the technical and musical characteristics of its original while fully meeting the demands of today's audiophiles. Through careful revision, the amplifier remains a true collector's item, delighting with sonic precision, high reliability, and an unmistakable sound character. An absolute must for hi-fi enthusiasts seeking technical precision, authentic sound quality, and emotional depth in their music reproduction—a true highlight in any high-quality audio system.
