The Quad 33 Pre Amplifier + 303 Power Amplifier have set the standard for desirable audio equipment in just about every aspect. Performance, reliability, industrial design, value and musical romance. QUAD, by re-introducing the QUAD 33 and 303 units, is showing its real nature, line of descent and excellence as one of the giant players of the British hi-fi world – both past and present.
Quad 33 Pre Amplifier + 303 Power Amplifier
The preamplifier and power amplifier work together seamlessly to reveal the perfection of the audio signal path. Quad demonstrates its sincere and highly exacting sound engineering.
Legendary Design and Engineering
Beautiful yet modest. The new and redesigned Quad 33 Pre Amplifier + 303 Power Amplifier embodies the evolution and engineering practice of industrial, functional, and durable British design. It perfectly harmonises with the power performance 303.
Excelelnt Sound Quality
A key feature of the new and redesigned Quad 33 Pre Amplifier + 303 Power Amplifier’s outstanding merit is its incredible sound quality, which enables warm, clear, and natural listening. This allows for enhanced clarity and exceptional sound reproduction.
140 Watts into 8 ohms
The novel version features an entirely complementary output stage, which achieves better linearity and stability. Resulting in improved sound quality even under challenging circumstances. It also features a custom low-noise toroidal transformer and advanced feedback topology.
It is possible to bridge it as a mono amplifier with a bridged power rating of 140W @ 8 ohms. Connecting two Quad 303 amplifiers will quickly satisfy even the most demanding loudspeaker, maintaining the iconic design and perfect construction.
The original triple-output stage includes an upgraded toroidal transformer capable of driving 4-ohm loads with 70 Watts per channel. It can also be used in bridge mode to output 140 Watts into an 8-ohm load.
Connectivity
The new and redesigned Quad 33 Pre Amplifier + 303 Power Amplifier. They accept multiple inputs, enabling the connection of various devices, and are available as single standalone units, receivers, or energy units, thus giving consumers a lot of flexibility.
Features and Benefits
- Iconic Design: These models are built with durable construction and have become synonymous with some of the most iconic hi-fi designs.
- Exceptional Sound Quality: High-quality replica of vinyl sound without overproduction pitfalls. Thanks to the clear and detailed reproduction.
- Vinyl Playback Excellence: A phono stage with a proven track record of excellence with vinyl records.
- Flexibility: They offer multiple options that enable users to connect various devices. Such as a turntable or CD player, to the digital streaming adapter via an additional DAC.
Summary of the Quad 33 Pre Amplifier + 303 Power Amplifier
When the idea to make these two models again was born. The whole team sternly agreed that the new 33 and 303 combination will be released only if the performance is on par with and even better than the original.
Low Noise Toroidal Transformer
It is perhaps a bit daring but still reasonable to say that in terms of technology, a low-noise. Specially made toroidal transformer, a number of reservoir/smoothing capacitors. An amazing amount of regulators have essentially put the new QUAD 33 ahead of the old one.
Technical Innovations and Enhancements
The power supply boasts five regulated supply rails, between which multiple ultra-low-noise regulators operate, extensively guarded against contamination and cross-coupling.
