Taking its stylistic cues from QUAD's iconic 22 and 33 preamps, the Quad 3 integrated amplifier combines classic QUAD DNA with cutting-edge technology. This all-in-one solution delivers audiophile-grade performance in a compact footprint perfect for modern living spaces.
Digital Excellence:
At the heart of the Quad 3 lies the ESS Sabre ES9038Q2M 32-bit DAC, supporting ultra-high-resolution audio up to 768kHz PCM and DSD512. Full MQA decoding ensures you extract maximum detail from high-resolution sources, while Roon Tested certification guarantees seamless integration with modern streaming ecosystems.
Versatile Connectivity:
- USB-B input for PC/Mac (up to 32-bit/768kHz PCM, DSD512)
- HDMI ARC for TV integration with remote control capability
- Coaxial and optical S/PDIF inputs (up to 192kHz)
- Bluetooth 5.1 with aptX HD for 24-bit wireless streaming
- Two analogue RCA line-level inputs
- Dedicated MM phono stage for turntables
- Pre-amplifier output for external power amps or subwoofers
- 6.3mm headphone output with dedicated current-feedback amplifier
Power and Performance:
The Class AB output stage employs Quad's Complementary Feedback (CFB) topology for superior linearity and thermal stability. Powered by a robust 235VA ultra-low-noise toroidal transformer with 30,000µF reservoir capacitors, the Quad 3 delivers 65W per channel into 8 ohms (100W into 4 ohms) with exceptional control and dynamic headroom.
Classic Control:
Signature features include flush-mounted digital encoders for volume, source selection, balance, bass adjustment (+/-3dB), and Quad's renowned Tilt control that adjusts the frequency spectrum on a 700Hz axis for personalized sound tuning. The orange LED display pays homage to vintage Quad designs while providing intuitive feedback.
