The DR.DAC3 is a USB DAC and headphone amplifier equipped with a variety of inputs and outputs, providing a compact, high-end playback environment for computer-based audio systems.

■ USB 2.0 Hi-Speed (480Mbps)
- Equipped with a high-performance USB controller chipset that supports 24-bit/192kHz (asynchronous). Connect to the USB port of a desktop or laptop computer and use it as a Hi-Fi USB DAC. Supporting high-resonance sound sources, it reproduces digital information losslessly, allowing you to enjoy rich, superior sound.
■ Dynamic Range/129dB
- Uses the PCM1794, the top-of-the-line chip in Ti's high-performance PCM series D/A converter. Fully compatible with 192kHz/24-bit signals, it achieves an astounding resolution of 129dB dynamic range (THD+N 0.0004%). It outputs digital signals input via optical, coaxial, or USB to their theoretical limits, providing the ultimate audio experience.
■ High-Performance FDO Op-Amp Circuit
- Equipped with an FDO (Full Differential Output) triple op-amp circuit, used in high-end Hi-Fi audio systems. The headphone output and line output terminals are equipped with New Japan Radio's high-end audio op-amp ""MUSE8920,"" reproducing a rich reverberation and a realistic sound field. The op-amp also features an interchangeable socket, allowing you to tune the sound to your liking.
■ High-Performance Headphone Amplifier
- Equipped with Ti's premium headphone amplifier chipset ""TPA6120A,"" boasting powerful driving power and outstanding resolution. Boasting a dynamic range of 129dB, it provides ample driving power even when using 600Ω studio monitor headphones.
