Built around a dual ROHM BD34302EKV DAC array in a true dual-mono configuration, with a built-in 10 MHz OCXO master clock delivering +\/-3 ppb stability, dual custom toroidal transformers providing independent power to the digital and analog stages, an XMOS XU-316 processor for PCM 32-bit\/768kHz and native DSD512, and a Qualcomm Bluetooth 5.4 platform supporting LDAC, the D3R delivers a measured 123 dB dynamic range, 0.00013% THD+N through its fully-balanced XLR outputs, and a 3.49-inch tempered glass color display — all housed in a substantial 3.81 kg CNC-machined aluminum chassis that announces its flagship intentions before a single note is played.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDual ROHM BD34302EKV in True Dual-Mono Configuration\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eEach channel of the D3R receives its own dedicated ROHM BD34302EKV DAC chip from ROHM's MUS-IC series, operating independently with separate power regulation and signal paths. This dual-mono architecture dramatically improves channel separation while reducing stereo crosstalk. The measured results speak for themselves: 123 dB dynamic range and SNR through the balanced XLR outputs, 122 dB through RCA, with THD+N of just 0.00013% (XLR) and 0.00017% (RCA).\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003e10 MHz OCXO Master Clock with +\/-3 ppb Stability\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAt the timing heart of the D3R is a built-in oven-controlled crystal oscillator (OCXO) generating a precision 10 MHz master clock. With frequency stability rated at +\/-3 parts per billion, this is the same class of timing reference found in laboratory instrumentation. The OCXO maintains its crystal at a constant elevated temperature inside a miniature oven, virtually eliminating the frequency drift caused by ambient temperature changes. A dedicated external clock input allows integration with an even higher-grade reference if desired.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDual Toroidal Transformers: Independent Digital and Analog Power\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eTwo custom-wound toroidal transformers separately feed the digital processing and analog output stages. This physical and electrical separation prevents high-frequency digital noise from contaminating the sensitive analog signal path. Multiple stages of low-noise regulation follow each transformer, ensuring that every active component in the D3R receives clean, stable, isolated power.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eXMOS XU-316 with Full Format Support\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe XMOS XU-316 USB interface is the latest-generation processor for high-resolution audio, supporting PCM at 32-bit depth up to 768 kHz sampling rate and native DSD512. Full MQA and MQA-CD hardware decoding is available across USB, optical, coaxial, and AES\/EBU inputs.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eFully-Balanced Analog Architecture\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eFrom the DAC output stage through the precision volume control to the XLR output jacks, the entire analog signal path maintains a true balanced differential topology. This end-to-end balanced design actively cancels common-mode noise and preserves the full dynamic range and channel separation achieved at the conversion stage. The XLR outputs deliver a robust 5.2 Vrms, while the RCA outputs provide 2.5 Vrms.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQualcomm Bluetooth 5.4 with LDAC\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe D3R incorporates Qualcomm's latest Bluetooth 5.4 platform, supporting LDAC at up to 990 kbps for near-lossless wireless transmission, alongside aptX, aptX HD, AAC, and SBC codecs. Wireless playback benefits from the same dual BD34302EKV conversion, OCXO clocking, and fully-balanced output stage as every other input.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eComprehensive Digital Connectivity\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eInputs include USB-B and USB-C, optical and coaxial SPDIF, AES\/EBU on XLR, and I2S via HDMI LVDS. Balanced XLR and single-ended RCA analog outputs feed your amplification.
