xDuoo R2R DAC Card for XD05 Pro & TA-32 – Pure Vinyl-Like Sound
Bring the warmth of analog into the digital world with the xDuoo R2R DAC Card, designed for audiophiles who crave natural tonality and musical texture. Built on a discrete 32-bit R2R resistor ladder architecture with FPGA compensation, this upgrade card transforms your listening experience on the xDuoo XD05 Pro or TA-32 amplifier.
Unlike typical Delta-Sigma DACs, the R2R approach focuses on organic sound reproduction—smooth highs, lush mids, and bass that feels full-bodied yet controlled. Whether you enjoy vinyl’s nostalgic warmth or want fatigue-free digital playback, this DAC card delivers a musical and natural presentation that feels alive.
At its core, the R2R card employs 128 precision thin-film resistors with 0.1% accuracy and independent left/right circuits for optimal channel separation. The FPGA 57-bit accumulator algorithm corrects timing and phase errors, ensuring accuracy without losing musicality.
With native PCM and DSD decoding up to DSD512, low-jitter clocking, and a NOS (No Oversampling) mode, the xDuoo R2R DAC Card blends high-resolution performance with a classic, analog-inspired sound signature—making it a perfect match for discerning audiophiles.
