Overview
The HA-3 was developed for headphone lovers searching exclusively the very special music experience. It impresses with its Single-Ended-Triode technology taken to its respective extremes by Ayon in all their products. Selected in-house AA45 Mesh super triodes, the perhaps most perfect and best sounding low-power triode for headphone amp design, are applied in combination with special super-permalloy wound output transformers. At the HA-3 deliberately all useless gimmicks have been omitted. The HA-3 is designed without compromise in its circuitry as well as in its power conditioning; therefore, a separate top-class power supply was inevitable; on the one hand, it guarantees extraordinary voltage and current stability and lowest hum.
