A true Masterpiece

The 430HA is a genuine masterpiece loaded with numerous state-of-the-art features. This fully balanced, pure analog amplifier using a discrete transconductance circuit topology, selectable gain setting (14 or 20dB), an oversized power supply. Rated at 667mW at 600 ohms and 8W at 50 ohms, the 430HA will effortlessly drive any headphone to its full potential.

Unique technologies

For headphone enthusiasts who desire perfection, the 430HA is the ultimate solution. Borrowing various technologies from our most exotic 600+ series (M-LoVo, M-eVOL2) while incorporating the most advanced analog audio circuitry, the 430HA will achieve the very best possible sonic performance from your headphones. It is also equipped with a defeatable Crossfeed circuit to render a more natural listening experience with headphones.

Key features

The 430HA can be used with the finest external DAC available. At your choice, an optional DSD256 and 32-bit/384kHz PCM capable DAC is available for the convenience of a single box solution.
