Cambridge Audio Azur 651A Amplifier


Inside the Cambridge 651A Amplifier is a fully balanced dual differential circuit usually not found in amplifiers under the $2000 price range. The fully dual differential amps ensures that any noise and variation of parts are rejected. Lower noise means finer detail and resolution. The Cambridge 651A amplifier has a Toroidial transformer which is more efficient and generate less hum and noise and EI core Transformer. There are Individual Taps for the Left and Right Channels making it Dual-Mono for better separation. The Cambridge 651A comes with a high grade Film Type Volume Control often used to modify other amps for get higher performance.
