Description

Details

HUD-DX1 allows its users to enjoy high-level Hi-Fi sound world by supporting replay of high-quality DSD sound source (2.8/5.6MHz) in native mode using USB bus power alone, DXD sound source (352.8/384kHz), another high-quality sound format, as well as optical input (24bit 192kHz) and MQS (Mastering Quality Sound, 96~192kHz), Hi-Fi sound source, without any loss rendered in studio recording specification. HUD-DX1 also allows its users to enjoy sounds with even higher output and high-quality sound when additionally connecting to the adaptor provided together.

Luxurious Black and Neat White color
You can meet two colors of HUD-DX1. Black color shows luxurious and stable shape with the assembly of gold volume knob and spike, while white color shows neat and sophisticated shape with the assembly of silver knob and spike.

Playback of Native DSD
Equipped with the newest USB 2.0 high speed audio controller from XMOS and ES9018K2M, a high performance DAC from ESS, it supports playback of Native DSD (DSD64 / DSD128) as it plays back sounds in excellent definition and Hi-Fi audio quality.

Additionally supports playback of 32-bit/384 kHz DXD sound source and optical input
Since HUD-DX1 is designed to support not only the playback of DXD sounds in 24-bit/352.8 kHz format, but also to support optical input functions that are not supported by products from other companies. It allows users to convert a maximum 24-bit/192 kHz PCM digital signal into a high quality analog sound output and play it back.

Top class OPAMP and high performance headphone amp
Adopting the MUSES series OPAMP, a top class one specifically designed for Hi-Fi audio products by NJRC, HUD-DX1 uses MUSE8920 for its I/V converter and filter circuits for excellent matching in sound quality and optimum constitution that realizes high performance and high fidelity audio with top class sound balance and very low distortion, as well as ultra-low noise. Also equipped with TPA6120A2, a high fidelity headphone amplifier from TI, it easily operates a headphone under 300 Ω in factory default mode and allows users to enjoy sounds with enough volume, even when using a 600 Ω high impedance headphone by removing jumper caps (JP1, JP2) set for headphone output gain.

Convenient Portability and Compatibility
Typical hi-fi DAC is inconvenient to carry around due to its large size, yet USB DAC has the advantage of being small and lightweight for the purpose of using it connected to the computer. As the unit gets smaller, the function of DAC reaches its limit and sacrifices with low quality audio sound. Our HUD-mx2 has overcome such limit to the maximum, developing ultra lightweight, compact DAC with reduced drop-off in audio quality. You can enjoy the music with highest quality possible audio sound wherever the computer is and, with its plug and play function.

Adopts genuine Thesycon driver
We adopted the driver from Thesycon, a German system software development company, by licensing to offer 100% functionality of high sound quality of Native DSD and stable audio playback. The Thesycon driver can be downloaded from the data center of the AUDINST website. Users can download it to an Internet-capable computer.
