Gustard has introduced the new DAC-X30 , the heart of which is 4 ES9039SPRO DAC chips from ESS.
Passive analog preamp
Adjust the volume using the R2R relay without losing sound quality. Possibility of passing a preamplifier through the output. Can be directly connected to active studio monitors or power amplifiers, conveniently controlled by remote control.
Programmable logic chip FPGA
Digital integrated circuits with proprietary logic, clock control, 2nd order PLL digital processing, DOP demodulation and PCM/DSD noise canceling switch. Provide excellent sound quality.
Chip ES9039SPRO x 4
Uses 4 ES9039SPRO chips for decoding, two per channel for a complete balanced architecture. Independently powered and grounded for maximum performance.
Digital DSP filter
Based on the DSP SHARC platform, a new digital filter with high-performance noise reduction algorithms has been developed. Reduces noise in digital audio streams and improves sound quality.
Analogue low-pass filter circuit
Class A discrete circuit specially designed for ES9039SPRO chip. Each device can be adjusted individually, allowing flexible settings to achieve the best operating conditions and minimize distortion.
CelWare bridge system
Completely developed in collaboration with Celaudio:
- Removes all hardware components not related to music playback.
- Based on the CelWare 3.x music playback system with an optimized Linux kernel to minimize latency and jitter.
- Software control of playback applications for maximum system efficiency.
K2 synchronized implantable watch technology
Uses a local OCXO clock or an external 10M clock synthesized and synchronously implemented for decoding. Improves decoding performance and reduces system dependency.
