It debuts a proprietary 32-element PSRM decoding module and a new I\/V conversion circuit, both engineered for ultra-low noise and high-fidelity playback. An independent preamp circuit, versatile digital inputs including USB-C, AES, and IIS-LVDS, Bluetooth 5.1 with LDAC, and the Aurora UI complete an ultra-flagship DAC built to pair seamlessly with computers, CD players, gaming consoles, and digital transports.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProprietary 32-Element PSRM Module\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe D900 uses a discrete 1-bit PSRM (Parallel Symmetrical Reference Module) decoding architecture in which 32 discrete elements work in concert to minimize power supply interference while preserving signal integrity. With nanosecond-level digital switching and a purely resistive reference power supply, it achieves harmonic distortion below -140dB and an SNR of 131dB – a hallmark of true reference-grade DAC design.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProprietary I\/V Conversion Circuit\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eTOPPING’s in-house I\/V circuit combines low-distortion op-amps with ultra-low noise discrete components – carefully selected after repeated testing – to keep the PSRM voltage output pristine, delivering ample dynamics and an immersive, lifelike sound experience.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eUltra-Low Jitter Clocking\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eCPLD-optimized clock signals deliver ultra-low jitter, measured at an impressive -157dB.
