• ES9039SPRO X4. Adopting 4 pieces of ESS flagship chip ES9039SPRO for decoding, two pieces per channel to form a fully balanced architecture, completely independent power supply, independent grounding, to obtain the best performance.
• K2 Synthesizer Synchronized clock lmplant Technology. Local OCXO clock or external 10M clock, synthesized a high-precision clock signal and then synchronously implanted for decoding. The front-end clock is discarded, and the DAC only uses the local OCXO clock or external 10M clock. Because of these front-end clock performance on the decodinc link greatly reduces the impact of the system on the performance of the front-end audio equipment to reduce the degree of dependence.
• FPGA Programmable Logic Chip. Digital integrated circuits with self-constructed logic functions clock management, 2nd PLL digital shaping, DOP demodulation, PCM/DSD depop switch, and other exclusive technologies provide a solid foundation for excelent sound quality.
• Analog LPF Circuit. The analog LPF circuit is a discrete Class A circuit designed especially for the ES9039PRO chip. Since each discrete device only needs to consider its own performance individually, there are fewer application limitations for this one device alone, so the performance of a single component can be fully utilized.
• Passive analog preamp R2R relay volume adjustment without loss of sound quality can also skip the preamp through the output. Can be directly connected to active studio monitor speakers or power amplifier, convenient and quick adjustment by remote control.
