SMSL VMV D2R MK2 Reference Desktop DAC
Re-discover analog warmth. Driven by a flagship ROHM BD34302EKV decoding chip, a built-in high-precision OCXO master clock, and a fully balanced analog pre-amp stage.
Six Core Pillars of Fidelity
ROHM Flagship Chipset
Utilizes a premium ROHM BD34302EKV DAC chip to deliver a smooth, natural, and non-fatiguing musical signature.
±5ppb OCXO Crystal
Built-in Oven-Controlled Crystal Oscillator maintains strict thermal stability for master-grade clock accuracy.
Full MQA Decoding
Complete MQA and MQA-CD unfolding across USB, Coaxial, Optical, and AES digital interfaces.
Balanced Analog Pre-Amp
Fully balanced analog volume control circuitry supports true pre-amplifier functions for direct active monitoring.
Linear Power Engine
Multi-channel low-noise regulation combined with patented adaptive mains voltage switching.
1.9" Tempered Glass IPS
Vibrant full-lamination IPS color display offers real-time track metadata and lyric readouts.
The Velvet Texture of Flagship ROHM Silicon
Symphonies demand depth and emotion. The SMSL VMV D2R MK2 desktop audio DAC implements the highly revered ROHM BD34302EKV flagship decoding chip, celebrated by music purists for its organic, lifelike midrange representation. Delivering an ultra-low THD+N of 0.00013% (-117dB), it processes complex audio files through a powerful 32-bit XMOS XU-316 USB solution, providing native support up to PCM 768kHz, DSD512, and full 8x MQA unfolding.
Thermal Jitter Isolation: Built-In ±5ppb OCXO
In digital audio, tiny timing slips distort spatial imaging. The VMV D2R MK2 guards against digital jitter with a built-in Oven-Controlled Crystal Oscillator (OCXO), which operates inside a temperature-regulated chamber to maintain a timing precision of ±5ppb. Driven by the custom CK-04 clock circuit, the system supports external standard 10MHz master or atomic clock inputs, letting you synchronize your entire digital source stack with perfect timing accuracy.
High-Res Bluetooth Lyrics & Variable Pre-Amp Stages
Enjoy modern streaming versatility without sonic compromise. Qualcomm's latest Bluetooth v5.4 module supports LDAC (24-bit/96kHz), aptX HD, and AAC. The D2R MK2's 1.9-inch color IPS screen displays real-time song info and synchronized lyrics directly on the front panel. Underneath, a built-in fully balanced analog volume control module lets you toggle between FIXED line-out and VARIABLE volume pre-out, allowing the DAC to drive high-end active studio monitors directly.
Sonic Customization Dashboard
Tune your audio architecture dynamically. The VMV D2R MK2 integrates deep DSP control parameters, allowing you to shape acoustic decays, low-pass cuts, and signal phases directly:
Select between transient-accurate sharp roll-offs for modern acoustic clarity, or slow roll-offs for relaxed, natural acoustic decays.
Frequently Asked Questions
How does the ROHM BD34302EKV DAC sound compared to AKM or ESS? +
ROHM's flagship BD34302EKV chip is renowned for its organic, natural, and full-bodied presentation, particularly in the mid-range. While ESS often prioritizes extreme clean-edge detail and AKM delivers smooth neutrality, ROHM captures an analog-like fluid texture and emotional warmth reminiscent of high-end vintage gear, without sacrificing transient speed.
What is the purpose of the built-in ±5ppb OCXO crystal oscillator? +
The Oven-Controlled Crystal Oscillator (OCXO) isolates the internal timing crystal inside a small heated chamber, maintaining a strict constant temperature. This prevents clock frequency drift caused by shifting room climates, lowering clock jitter to a near-immeasurable level and securing stable spatial imaging.
Can I bypass the internal pre-amp for line-out use? +
Yes. The D2R MK2 features a dedicated "PRE MODE" switch in the menu. You can select FIXED mode to bypass the analog volume controller entirely for a pure, reference line-level output, or VARIABLE mode to adjust volume directly on the DAC.
What does the "BEST SET" option do? +
The BEST SET is a one-key optimization macro. When activated via the menu, the DAC automatically switches output routing, PCM roll-off filters, DSD low-pass filters, and Sound Color profiles to their absolute best-performance configurations, providing a reference master-tuning benchmark instantly.
Does the D2R MK2 support external master clock synchronization? +
Yes, it features a rear 10MHz master clock input port, supporting standard 10MHz signals or atomic clocks. It also lets you toggle input impedance between 50Ω and 75Ω inside the menu to avoid signal reflection over clock cables.
