1794 Dual Core Parallel PCM1794 DAC Decoder 192KHz 24Bit Coaxial Optical Input (Upgraded Version)

1794 Dual Core Parallel PCM1794 DAC Decoder 192KHz 24Bit Coaxial Optical Input (Upgraded Version)

Description:
It is the latest version, with voltage regulator upgraded to 3pcs LT1963 high-end regulators.

Version Comparison:
- Standard Version: Op amp with 3pcs TL072.
- Upgraded Version: Op amp with 3pcs American OPA1612 high precision operational amplifiers.

Advantages:
- Core PCM1794 decoding. Details, dynamics and sound field are very good
- Coaxial and optical input adopt WM8805 demodulation, which is a higher grade than the common CS8416 on the market, with low time base jitter and good compatibility, no popping, and easy transmission of 192K 24BIT data
- Using low-distortion op amp OPA1612 low-pass, the effect is better than that of OPA2604. The sound is transparent and delicate, natural and bright. With gold-plated IC socket, you can freely replace and upgrade the op amp
- Using resistor-capacitor matching components and linear voltage regulator integration, make the circuit performance fully play. With components for WIMA, capacitors for ELNA, high-quality chip resistors for TDK and the like
- Aluminum alloy case with laser lettering is fashionable and durable
- Excellent performance with cheap price

Features:
- PCM1794A dual cores are connected in parallel. 192KHz, 24Bit
- 2pcs PCM1794A, each piece is responsible for one sound channel, which greatly improves sound density and separation, the sense of air and sound field is improved!
- LT1963 voltage regulator, large current, high precision and low internal resistance. The noise is as low as 20UV, which is an ultra-low ripple of 0.02MV, allowing PCM1794 to work in the most ideal state.
- Both I/V conversion and low-pass use OPA1612 dual op amp. OPA1612 (dual channel) bipolar input op amp can achieve very low noise density (1.1nV/√Hz) and ultra-low distortion (0.000015%) at 1kHz. The OPA1612 can provide rail-to-rail output with a swing range of 600mV from the power rail under a 2-k load, which helps to maximize the dynamic range. Performance surpasses that of LME49720 and LME49710
- Hermetic transformer boasts low magnetic leakage and high efficiency. It is the most basic guarantee for the sound of the whole machine. Next to it is the high-speed filter capacitor for Panasonic for FC audio
