"…the AX-5 is not only, overall, the finest-sounding amp I’ve ever heard, it ranks as one of the finest components I’ve heard of any type.” –Uday Reddy, SoundStage!

Featuring Ayre's new Double Diamond output stage, our exclusive EquiLock circuitry, and a Shallco solid-silver contact switch for gain control, this fully-discrete, fully-balanced, zero-feedback integrated amplifier provides a complete solution for your modern music system.

The key to perfecting the AX-5 Twenty was to incorporate the Variable Gain Technology (VGT) of the award-winning Ayre KX-R Twenty preamplifier into the power amplifier section. The addition of ultra-transparent FET input selector switches completed the transformation of a basic power amplifier into a compact one-box solution which will become the heart of your high-performance audio system.

Twenty Series Updates

 

  • AyreLock power supply - All power supply regulators, whether 3-pin ICs using massive amounts of feedback or the discrete zero-feedback designs Ayre has always used in every product ever since the V-3, twenty-one years ago, have at their heart a single series-pass active element (tube, FET, or BJT).

 

When the load (audio circuit) draws more current, the pass element decreases its resistance (turns on harder), to keep the voltage to the load constant.

 

  • For the AyreLock in the Twenty update, Ayre added a second circuit element (in Ayre's case a BJT) that also pulls down. So when the load (audiocircuit) draw less current, the second transistor draws additional current to ground.

    The analogy is like going from a single-ended output stage in a power amp to a push-pull complementary output stage. This "locks" the output voltage of the regulator, regardless of any fluctuations in the load.

     

  • Improved Diamond output stage - The Diamond output stage as you know is an incredible output stage, one of the best sounding design available. But, it produces a high level of heat in an amplifier design. We designed the Double Diamond output stage to solve the heat issue and we successfully reduced the operating temperature by 35%, keeping it below human body temperature. The new circuit design is a little more powerful than the previous version and has amazing power and control in the lower frequencies.
  • Servo controlled DC offset - Ayre has replaced the trimpots that they used in the original KX-5 and AX-5 with a much better sounding servo control. This servo no only improves the sound of the unit, but it also keeps the DC offset to less than 15 mv. It will even be able to compensate for incoming DC from a source component (up to a certain level).
