QUAD 33 Pre-Amplifier (2025 Version)
The new QUAD 33 Pre-Amplifier is a modern reimagining of one of hi-fi’s most iconic control units. Retaining the unmistakable simplicity of the original design, it now incorporates contemporary features such as a backlit display, LED illumination, and full remote control functionality—blending heritage with modern usability.
Despite its updated digital control interface, the QUAD 33 remains fundamentally analogue at heart. With a short, direct signal path and carefully engineered circuitry, it delivers exceptional clarity, low noise, and faithful musical reproduction—staying true to QUAD’s philosophy of “the closest approach to the original sound.”
The inclusion of a high-performance MM/MC phono stage, balanced connectivity, and QUAD’s signature Tilt control makes this a highly versatile and musically engaging preamplifier for both vinyl and modern sources.
