D90 III Discrete Full Balance HiFi DAC Preamplifier - BT 5.1 Support LDAC PEQ Adjustment with Bluetooth Remote Control (Black)

Brand new
PSRM module: The D90 III Discrete features 16-phase PSRM modules for each of the left and right channels. The PSRM is a discrete 1-bit DAC. It uses an advanced architecture consisting of an ultra-fast switching logic array and a precision voltage reference, which is the core of the PSRM circuit. After rigorous testing of more than 20 device types and configurations, we selected the best combination, which not only switches at amazing speeds but also maintains the integrity of the original signal. The components are selected to minimize any disturbance to the voltage reference power supply, thus ensuring excellent performance and reliability.; The power supply design of the voltage reference is also very important and is crucial to ensure the accuracy of the analog output. Our digital logic switches switch at the nanosecond level with sharp rising and falling edges, which may generate noise that interferes with the analog signal. To solve this problem, we pioneered the design of a stable, noise-free pure resistance output power supply, which enables each DAC component to achieve extremely precise output. As a result, we can reproduce the original audio with amazing fidelity, achieving 130 dB DNR and 131 dB SNR.
