Reference ROHM R-2R DAC with Dual BD34302EKV Architecture

The SMSL VMV D2R MK2 is a flagship desktop digital-to-analog converter built around a dual ROHM BD34302EKV DAC array from ROHM's prestigious MUS-IC series. With SMSL's self-developed CK-03 ultra-low-jitter clock circuit, a custom linear power supply centered on a British toroidal transformer, fully-balanced XLR outputs, comprehensive digital connectivity including I2S and AES/EBU, and Qualcomm Bluetooth 5.1 with LDAC, the D2R MK2 delivers a measured 129 dB dynamic range, vanishingly low 0.00014% THD+N, and the rich, naturally textured sound that only a precision R-2R ladder DAC architecture can provide.

Dual ROHM BD34302EKV: Flagship MUS-IC Series DAC Chips

The D2R MK2 deploys two ROHM BD34302EKV converters — part of ROHM's MUS-IC series, purpose-built for high-end audio applications with proprietary sound quality design technology. Operating in a true dual-mono differential configuration, the dual-chip array delivers a measured dynamic range of 129 dB (XLR) and 125 dB (RCA), with total harmonic distortion plus noise of just 0.00014% (-117 dB). Every recording is rendered with the tonal density, spatial precision, and natural decay that distinguish reference-grade R-2R ladder conversion from conventional delta-sigma designs.

CK-03 Clock Processing Circuit

SMSL's CK-03 is a purpose-built, ultra-low-jitter clock circuit that dramatically reduces timing errors at the conversion stage. By slashing clock jitter before it reaches the DAC chips, the CK-03 preserves transient snap, stereo imaging precision, and high-frequency extension — transforming your audio streams into a stable, focused, and musically engaging presentation.

Custom Linear Power Supply with Toroidal Transformer

Power delivery is handled by a built-in linear power supply centered on a British toroidal transformer. Multiple low-noise, custom-regulated supply rails feed the digital, analog, and clock sections independently, preventing cross-contamination and ensuring that each stage of the DAC operates with a clean, stable power foundation. The result is a blacker background, improved micro-detail retrieval, and freedom from the high-frequency noise artifacts that plague switch-mode supplies.

JAS HI-Res and MQA Certified

The D2R MK2 carries official JAS (Japan Audio Society) Hi-Res Audio certification alongside full MQA and MQA-CD hardware decoding. These certifications are not marketing badges — they represent independent verification that the D2R MK2 meets rigorous performance standards for high-resolution playback. Stream MQA-encoded content from TIDAL or play MQA-CDs through a compatible transport, and the D2R MK2 unfolds and renders them with studio-authenticated accuracy.

Comprehensive Digital Connectivity

Six digital inputs provide maximum system flexibility:

USB: High-resolution PCM and DSD from computer sources
I2S (HDMI LVDS): Direct differential digital connection for the lowest jitter
AES/EBU (XLR): Balanced 110-ohm professional digital input
Coaxial (RCA): 75-ohm SPDIF for wide compatibility
Optical (TOSLINK): Galvanically isolated connection
Bluetooth 5.1: Qualcomm platform with LDAC, aptX HD, aptX, AAC, SBC

Balanced XLR and Single-Ended RCA Outputs

Output levels are generous and configurable. In fixed-volume mode, XLR outputs deliver 4.0 Vrms and RCA outputs deliver 2.0 Vrms. In variable-volume mode for direct connection to a power amplifier or active speakers, XLR outputs reach 5.1 Vrms and RCA outputs reach 2.6 Vrms. Output impedance is a low 200 ohms (XLR) and 100 ohms (RCA), ensuring compatibility with virtually any downstream component.

Bluetooth 5.1 with LDAC and aptX HD

A Qualcomm Bluetooth 5.1 platform provides high-resolution wireless streaming with support for LDAC, aptX HD, aptX, AAC, and SBC codecs. An external antenna ensures stable reception even in crowded RF environments. Bluetooth is more than a checklist feature here — it is a fully integrated, high-quality wireless input that benefits from the same CK-03 clocking and dual BD34302EKV conversion as every other input.

Precision Knob and Tempered Glass Display

A newly designed high-quality volume knob provides smooth, tactile adjustment with precise channel matching. The fully-laminated tempered glass display panel presents input selection, sampling rate, volume level, and format information with exceptional clarity and a refined aesthetic that matches the VMV series' flagship positioning.
