Completely redesigned KX-R Twenty has implemented all new Ayres’ visions at the highest level and became a ground-breaking amplifier comparative to the impact KX-R had back in the days originally introducing the first VGT volume control.

The new AyreLock power supply uses more than twice the capacity of the old power supply. Additionally, has a new type of discrete voltage regulation.

People say a stunning sense of realism that captivates you from the first note, has been gained by the impartment of the optimised current mirror and Ayre Diamond output stage.

All Ayre products have been explored in detail and tested from all possible aspects before officially being produced. Hundreds of, some would consider fanatical, hours of listening tests, checking the smallest details of the entire audio path and pushing this amplifier to the edge of excellence have been devoted by the cherry-picked Ayre team. You are welcome to enjoy and celebrate twenty years of journey and creation with the KX-R Twenty.

The sound was open and driving and rhythmic and dynamic—very dynamic. It was… it was… you had to be there. I’m sure glad I was.
