VX-5 Twenty Stereo Amplifier (Silver)

The Ayre VX-5 Twenty fully-discrete, fully-balanced, zero-feedback amplifier features our exclusive Equilock circuitry and our Diamond output stage giving it both the power and control for the most demanding musical passages. The VX-5 is every bit the refined and sublime musical masterpiece you have come to expect from an Ayre product. With the addition of our new Diamond output stage this amplifier packs a punch so palpable you will find yourself clinging to the essence of every note. Make a VX-5 the foundation of your music system and redefine your expectation of what an amplifier should do.

“All told, Ayre's new VX-5 is as perfect a power amp as I've seen lately for the audiophile who wants high performance and high value.”

– Doug Schneider, SoundStage!

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.
