The Audio Research Reference DAC is a high-end digital-to-analog converter designed to provide the highest possible sound quality in digital playback. It uses advanced technologies and premium components to deliver accurate, detailed, and musical reproduction of digital signals. Some of its notable features include:1. Multiple input options: The DAC supports PCM data up to 32-bit/768kHz and DSD data up to DSD256 via USB, AES/EBU, and BNC inputs.2. Proprietary filters: Audio Research has developed two proprietary filters, musical and critical, to provide different trade-offs between resolution and tonality. The musical filter is designed to prioritize detail and clarity, while the critical filter is more neutral and resolving.3. Low-noise power supply: The Audio Research Reference DAC uses a low-noise, dual-mono power supply with multiple voltage regulators to provide a stable and clean power source for the converter and the rest of the system.4. High-quality components: The DAC utilizes premium components such as the SN74LV Webbster 74LS op-amps, Vishay Dale Resistors, and WBT NextGen RCAs to minimize noise and distortion and maximize signal purity.5. User-selectable upsampling: The DAC has a user-selectable upsampler that can double, quadruple, or octuple the sampling rate of PCM signals to improve resolution and reduce aliasing.6. Zero-tolerance voltage regulation: The DAC features zero-tolerance voltage regulation on the analog stages to maintain the desired output levels and minimize noise.7. Sophisticated clocking: The DAC uses a sophisticated clocking system, including a "super" crystal found in watches and a dedicated clock engine, to ensure precise timing and minimal jitter for improved sound quality.Overall, the Audio Research Reference DAC is a top-of-the-line DAC that caters to audiophiles who demand the ultimate in sound quality, detail, and musicality from their digital sources. Its sophisticated features and high-quality components make it one of the most sought-after DACs in the market.
