• The Quad 303: A High-Fidelity Powerhouse

  Ideal for powering any loudspeaker between 4 and 16 ohms, the Quad 303 delivers smooth, high-quality audio to your home. Each channel produces up to 45 watts, driven by an ingenious transistor circuit for flawless performance.

  Unmatched Clarity and Stability:

  Distortion-free: Forget about unwanted noise. The 303's audio range boasts incredibly low harmonic and intermodulation distortion. Transistor triples are employed to provide a completely symmetrical output stage, quiescent current independent of junction temperature, and symmetrical current and voltage limiting.

  Stable design: No matter the load, this amplifier stays under control. Drive any speaker with confidence.

  Versatility and Power:

  Independent channels: Use both channels together or separately for ultimate flexibility.

  Low-impedance capability: Push the limits with continuous power for 4-ohm loads and below.

  Heat management: Extended use with demanding loads is no problem thanks to the efficient heat sink.

  Caution: Don't parallel the outputs without current sharing to avoid damage.

  The Quad 303 is a true legend in the audio world, built for discerning listeners who demand the best.
