Ayon Audio HA-3 MKII Tube Headphone Amplifier

The HA-3 II was developed for headphone lovers searching exclusively the very special music experience.

It will impress you with it’s Single-Ended-Triode technology taken to its respective extremes by Ayon–in all their products. Selected in-house AA45 Mesh super triodes, perhaps the most perfect and best sounding low-power triode for headphone amp design, are used in combination with special super-permalloy wound output transformers.

The HA-3 II deliberately omitted all useless gimmicks. The HA-3 II is designed without compromise in its circuitry as well as in its power conditioning; therefore, a separate top-class power supply was inevitable. It guarantees extraordinary voltage, current stability and the lowest hum.

With its powerful, airy, and lively play, paired with emotional reproduction and spatiality; the HA-3 II drives every dynamic headphone to an absolutely maximum tonal performance. It accentuates everything from treble in brilliant resolution, to absolutely authentic colourful mid-range and a deep resilient bass. At the same time, it fascinates us by its incredible ease in transition, it replicates reality and has control of any kind of reproduction that is second to none.

Vacuum Tubes
The choice of signal and power tubes have a significant influence on the sound, and hence, on the inspiration and joy of listening. This is not only the decision between good and bad tubes, but the interaction of the different types of tubes and their combination, that are used in the various Ayon amplifiers.

Signal Path
We believe that the simplest circuits work best together with the shortest signal path. The shorter the signal path is, the less possibility of sonic degradation from various sources, including the wire itself. Even on the circuit boards, the copper traces are kept to a very minimum length. The completely redesigned circuit board provides a more straightforward and direct approach to the signal paths.

Power Supply
The power supplies have been further refined with new components and enhanced AC line noise filtration. Separate power transformers, chokes and filters provide total isolation between the input and output stages which makes this a pure power source. We also use electrolytic capacitors with much larger storage capacity to make up for the loss in filtering when using resistors in lieu of inductors.

Output Transformer
The super-wide bandwidth output transformer’s major strength is that it can deliver the current in the bass, while at the same time maintaining the speed in the high frequencies. This dramatically improves the square wave response of the amplifier. The effect is a much more natural and relaxed sound with much better clarity, resolution and fluidity.

The type of parts used therefore must have a synergistic relationship to the circuit they are placed in. It is this relationship of which type of part to use where, that sets our products apart from the masses.

Mechanical Construction
The high grade aluminum chassis impart a richer, more lustrous tonality with a cleaner background and less hash and grain. All brushed anodized anti-vibration-resonance and non-magnetic chassis’s are fully hand assembled to insure the highest level of craftsmanship.
