{"type":"firestarter.listing","listing":{"id":"lst_4rV80h3r","product_name":"VMV D2R MKII Desktop DAC (Digital-to-Analog Converter)","category":"DAC (Digital-to-Analog Converter)","description":"Flagship ROHM DSD512 DAC\nThe VMV D2R MK2 is a flagship desktop DAC built around the ROHM BD34302EKV conversion platform, paired with a precision 10MHz OCXO clock system, XMOS XU316 USB processing, and a fully-balanced analog stage. Designed for high-resolution playback across USB, AES/EBU, optical, coaxial, Bluetooth, and I²S sources, the D2R MK2 supports PCM up to 768kHz, native DSD512, and full MQA decoding while maintaining ultra-low distortion and low-noise performance.\nReference-grade ROHM conversion\nAt the core of the D2R MK2 is the ROHM BD34302EKV DAC chip, selected for its low distortion characteristics and natural tonal balance. The fully-balanced signal path is engineered to preserve low-level detail and channel separation while maintaining stable output performance across both RCA and XLR connections. Balanced THD+N reaches as low as 0.00013% (-117dB).\nPrecision OCXO clock architecture\nThe integrated 10MHz OCXO crystal oscillator is designed to minimize phase noise and timing instability inside the digital audio chain. Rated at ±5ppb frequency stability, the oven-controlled clock reduces jitter caused by temperature fluctuation and timing drift, helping preserve spatial accuracy, transient definition, and image focus.\nHigh-resolution digital platform\nThe XMOS XU316 USB processor provides the computing headroom required for modern high-resolution playback formats. USB and I²S inputs support PCM up to 768kHz at 32-bit resolution alongside native DSD512 decoding. Optical, coaxial, and AES/EBU inputs support PCM up to 192kHz and DoP playback. Full MQA and MQA-CD decoding is supported through USB, optical, coaxial, and AES connections.\nFully-balanced analog output stage\nThe D2R MK2 uses a fully-balanced circuit topology with dedicated RCA and XLR outputs. The balanced XLR output stage delivers 5.0Vrms while maintaining a dynamic range of 123dB and a signal-to-noise ratio of 123dB. Careful separation between digital and analog sections helps reduce interference","images":["https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-vmv-dac-digital-to-analog-converter-vmv-dr2-mkii-desktop-dac-digital-to-analog-converter-1238062905.png?v=1778619430","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-vmv-dac-digital-to-analog-converter-vmv-dr2-mkii-desktop-dac-digital-to-analog-converter-1238062904.png?v=1778619369","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-vmv-dac-digital-to-analog-converter-vmv-dr2-mkii-desktop-dac-digital-to-analog-converter-1238062911.jpg?v=1778619311","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-vmv-dac-digital-to-analog-converter-vmv-dr2-mkii-desktop-dac-digital-to-analog-converter-1238062908.jpg?v=1778619252","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-vmv-dac-digital-to-analog-converter-vmv-dr2-mkii-desktop-dac-digital-to-analog-converter-1238062917.jpg?v=1778619191","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-vmv-dac-digital-to-analog-converter-vmv-dr2-mkii-desktop-dac-digital-to-analog-converter-1238062922.jpg?v=1778619130","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-vmv-dac-digital-to-analog-converter-vmv-dr2-mkii-desktop-dac-digital-to-analog-converter-1238062920.jpg?v=1778619069","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-vmv-dac-digital-to-analog-converter-vmv-dr2-mkii-desktop-dac-digital-to-analog-converter-1238062918.jpg?v=1778619011","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-vmv-dac-digital-to-analog-converter-vmv-dr2-mkii-desktop-dac-digital-to-analog-converter-1238062923.jpg?v=1778618948","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-vmv-dac-digital-to-analog-converter-vmv-dr2-mkii-desktop-dac-digital-to-analog-converter-1238062919.jpg?v=1778618891","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-vmv-dac-digital-to-analog-converter-vmv-dr2-mkii-desktop-dac-digital-to-analog-converter-1238062915.jpg?v=1778618832","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-vmv-dac-digital-to-analog-converter-vmv-dr2-mkii-desktop-dac-digital-to-analog-converter-1238062921.jpg?v=1778618771","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-vmv-dac-digital-to-analog-converter-vmv-dr2-mkii-desktop-dac-digital-to-analog-converter-1238062910.jpg?v=1778618710","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-vmv-dac-digital-to-analog-converter-vmv-dr2-mkii-desktop-dac-digital-to-analog-converter-1238062909.jpg?v=1778618651","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-vmv-dac-digital-to-analog-converter-vmv-dr2-mkii-desktop-dac-digital-to-analog-converter-1238062912.jpg?v=1778618591","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-vmv-dac-digital-to-analog-converter-vmv-dr2-mkii-desktop-dac-digital-to-analog-converter-1238062907.jpg?v=1778618529","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-vmv-dac-digital-to-analog-converter-vmv-dr2-mkii-desktop-dac-digital-to-analog-converter-1238062914.jpg?v=1778618471","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-vmv-dac-digital-to-analog-converter-vmv-dr2-mkii-desktop-dac-digital-to-analog-converter-1238062913.jpg?v=1778618411","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-vmv-dac-digital-to-analog-converter-vmv-dr2-mkii-desktop-dac-digital-to-analog-converter-1238062916.jpg?v=1778618350","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-vmv-dac-digital-to-analog-converter-vmv-dr2-mkii-desktop-dac-digital-to-analog-converter-1238062906.jpg?v=1778618289","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-vmv-dac-digital-to-analog-converter-vmv-dr2-mkii-desktop-dac-digital-to-analog-converter-1238062903.png?v=1778618232"],"price":1160,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:25:55.798Z"},"share_url":"https://firestarter.network/l/lst_4rV80h3r","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
