Classic High-End Pro-Ject DAC with exclusive modifications
The Final Edition includes two specially selected and matched diamond ECC88 high-end tubes, with an SRP of €199 per piece. These tubes elevate the audio performance even further, making the DAC Box RS the ultimate high-end bargain! Other electrical components have been meticulously selected so that only the best are used in the DAC Box RS Final Edition and the internal wiring has been improved.
The DAC Box RS is a reference-class D/A converter for digital stereo sources, designed for audiophiles who demand top-tier performance. It serves as a high-quality USB audio interface for HD computer audio and supports various inputs, including I²S with Master Clock, AES/EBU, optical, and coaxial.
With full DSD capability (up to DSD128) and support for 24/192kHz HD audio on all inputs (96/24 for optical), it ensures exceptional sound quality. The DAC Box RS features two premium PCM 1792 DAC chips and offers selectable digital filters to match your sound preferences.
Choose between a warm, relaxed tube output or a detailed, dynamic solid-state Class A output to suit your taste and music style. Its ultra-low noise, ultra-linear design, and low output impedance ensure a clean, interference-free signal.
