RD-7500 OTL/OCL DAC

Description

Design Goal: Minimization of Distortion (Straight Wire with Gain) The “Straight Wire with Gain”—the North Star of audio design—is the goal of delivering an input signal with zero modulation or processing, increasing only its magnitude with absolute precision. Unlike general amplifiers that amplify power, a DAC is a device that converts delicate digital signals into analog and transmits them to the next stage. Therefore, “precision” and “signal purity” are the highest priorities. To achieve this, the RD-7500 eliminates all interference that obstructs the signal flow throughout the entire digital and analog process. Digital Part: The World’s Most Precise DAC Chip (ESS ES9039PRO) Precise analog transmission begins with perfect digital reconstruction. The RD-7500 is equipped with the ES9039PRO, the flagship chip from ESS Technology, widely regarded as the finest DAC chip in existence. HyperStream IV Architecture: Utilizing 4th-generation technology, it undergoes a conversion process far more sophisticated than previous generations. Ultra-High Resolution Data Processing: Based on a 32-bit, 8-channel architecture, it achieves overwhelming Dynamic Range (DNR) and extreme Total Harmonic Distortion (THD+N). It perfectly restores even the micro-details hidden within digital sources. Methodology: Non-Feedback (Zero Negative Feedback) While Negative Feedback (NFB) is an engineering “correction tool” used to adjust measured figures, Non-Feedback is an “artistic frontal assault” that maximizes the inherent purity of the components.
