Tube and Solid-State Output Options
The DAC Box RS offers the flexibility of two distinct output stages, allowing users to choose between a warm, relaxed tube output or a more detailed, dynamic solid-state Class A output. This versatility lets you match the DAC’s output to your personal taste and the style of music you enjoy. The inclusion of ultra-low noise, ultra-linear design, and a low output impedance ensures that the DAC delivers a clean and interference-free signal, regardless of which output stage you choose.
Exclusive Final Edition Improvements
The Final Edition of the DAC Box RS takes audio performance to new heights with the inclusion of two specially selected and matched diamond ECC88 high-end tubes. These tubes enhance the overall sound, making the DAC Box RS an even more enticing option for audiophiles seeking top-tier performance at a competitive price. In addition to the upgraded tubes, the DAC Box RS Final Edition benefits from carefully chosen electrical components and improved internal wiring, ensuring only the finest materials are used.
Upgrade with Power Box RS2 Source
For audiophiles who demand the best, the Power Box RS2 Sources provides a significant upgrade to the DAC Box RS. While the included power supply is already of high quality, the Power Box RS2 Sources elevates the performance of the DAC to an exceptional level. A linear power supply, with a toroidal transformer and shielding between the primary and secondary windings, isolates the DAC’s sensitive circuitry from interference that can often come from mains power. The separate unit design of the Power Box RS2 Sources, encased in a sturdy aluminium housing, offers superior shielding compared to other solutions, ensuring that the DAC Box RS operates at its best.
Features
- Powers four 20V RS/RS2 devices
- One power supply for all source components
- Improved sound stage and detail resolution
- Cleanest power using non-switching power supply
- Soft start system avoids current inrush
- Audio type toroidal transformer
- Main isolating transformer with copper foil shielding
- Secondary voltage rectification with precise regulation
- High filtration capacity (10.000 μF)
- Low ESR capacitors
- Low noise components with surge protection
- Rigid aluminium casing protects against interference
- Available in silver or black
- Made in Europe
