TOPPING D90 III Discrete Fully Discrete 1-bit Full-Balanced DAC | Key Highlights Built with proprietary PSRM discrete resistor power supply and brand-new discrete I/V conversion circuit, D90 III Discrete achieves ultra-low THD+N below 0.00006%, 131dB SNR and 130dB dynamic range. CPLD clock optimization suppresses jitter to -157dB, delivering vivid, natural analog-style sound. It adopts XMOS USB processor to fully decode PCM 768kHz/32bit and native DSD512. QCC5125 Bluetooth 5.1 supports LDAC, aptX-Adaptive and other lossless formats, holding dual Hi-Res Audio & Hi-Res Wireless certifications. Rich digital ports cover IIS-LVDS, USB, Optical, Coaxial and AES. XLR balanced & RCA single-ended outputs work simultaneously with switchable 4V/5V XLR and 2V/2.5V RCA output levels. Built-in preamp mode directly drives power amps and active speakers, with 10-band high-precision PEQ for custom tuning via PC software. 12V trigger IN/OUT supports synchronized power control with amplifiers. 2.4G Bluetooth remote works through obstacles. CNC aluminum stackable chassis pairs perfectly with A90 Discrete to construct a flagship fully discrete balanced desktop HiFi system.
