The Neo 430HA is a genuine "tour de force" 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 and a defeatable analog crossfeed circuit. Rated at 667mW at 600 ohms and 8W at 50 ohms, the Neo 430HA will effortlessly drive any headphone to its full potential. 

For headphone enthusiasts who desire perfection, the Neo 430HA is the ultimate solution. Borrowing various technologies from our more exotic and costlier Evolution 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. The optional DSD256 and 32-bit PCM capable DAC can be used with virtually any digital source such as computer for streaming music, satellite TV receiver or Blu-Ray player, offering the same fidelity as your music system. 

Of course, key features you'd expect in a MOON Neo Series product are present such as 12V triggers and an RS-232 port for custom-install environments.

Note: Available finishes are dependant on location.

Technical aspects

Defeatable analog Crossfeed circuit for better 'spacialization' and listening comfort
Balanced Outputs hidden behind sliding front panel window (2x 3-pin XLR, 1x 4-pin XLR), as well as a 1/4" TRS jack, and both fixed & variable line-level single-ended RCA stereo pairs
An oversized power supply using 2 toroidal transformers in conjunction with 8 stages of DC voltage regulation
4 stages of our M-LoVo (MOON Low Voltage) DC regulation circuit; a highly sophisticated circuit that is virtually free of noise, yielding an exceptionally fast, precise, and stable DC voltage. This circuit, found in the Evolution series 810LP Phono Preamplifier and 740P Preamplifier, results in a power supply with a virtually unmeasureable noise floor
M-eVOL2 volume control circuit using MDAC's (operating in a current steering R-2R configuration) which alter the audio signal's amplitude, yielding no sonic degradation of the signal, regardless of the selected volume setting. This circuit, found in the Evolution series 600i & 700i Integrated Amplifiers and 740P Preamplifier, offers 530 steps and channel matching of 0.1dB
1 balanced XLR input and 3 single-ended line-level inputs, including a front-mounted 1/8" mini-jack for personal media players
Optional DAC with four (4) digital inputs (S/PDIF x 2, TosLink x 1 & USB x 1) allowing for use with virtually any digital source; Supports DSD64, DSD128 and DSD256 (USB input only); Supports PCM 16/44.4kHz to 24/192kHz (all inputs) and up to PCM 32/384kHz (USB input only)
EuP compatible eco-friendly power (less than 0.5W) in standby mode with defeatable 20 minutes inactivity "auto shut off"
12 Volt trigger output for remote operations
RS-232 port for (i) full unsolicited bidirectional feedback and (ii) firmware updates
IR input for external control
SimLink™ controller port for 2-way communications with other compatible MOON components
Rigid chassis construction to minimize the effects of external vibrations
