Two DAC Chips - Two Filters
The DAC Box RS supports HD music files at resolutions of up to 24-bit/192kHz (96/24 for optical inputs) in fully asynchronous mode, ensuring high precision and fidelity. At its core are two premium audio-grade DAC chips, the PCM 1792, renowned for their exceptional audio performance and usually found in high-end designs. To tailor sound to individual preferences, it offers two digital filter settings, allowing users to adjust sound characteristics to match their taste and music style. This level of customisation ensures that listeners can achieve their desired audio profile.
Choice of Output Stage for Personalised Sound
For ultimate flexibility, the DAC Box RS provides the option of a warm, relaxed output stage using tubes, or a highly detailed and dynamic solid-state Class A output. Both choices are expertly designed to meet the highest standards of audio reproduction. The DAC’s ultra-low noise, ultra-linear design with low output impedance prevents interference with cables or pre-amps, ensuring clarity and purity of sound. With its impressive range of features and superior audio quality, the DAC Box RS represents a high-end option at excellent value for audiophiles seeking class leading digital sound conversion.
