Arguably the most important component in your system, the KX-5 Twenty delivers all of the performance and flexibility you have come to expect from an Ayre product. Following in the legendary footsteps of the KX-R Twenty preamplifier, the Ayre KX-5 Twenty lives up to the challenge with dynamics powered by our newly revised Diamond output stage and a finesse achieved by eliminating the traditional attenuating volume control with our 46 position Variable Gain Transimpedance (VGT) amplification circuit.
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.
