SMSL Goes R2R

SMSL continues to roll out its high-end VMV desktop audio lineup with the VMV D3 R2R DAC. Unlike most modern-day DACs, which use delta sigma chips to handle D/A conversion, the D3 uses four discontinued Texas Instruments R2R chips in a two-chip-per-channel fully balanced design. 

4 Discontinued Texas Instruments R2R chips

The SMSL VMV D3 uses four discontinued PCM1704U-J Texas Instrument R2R chips for digital-to-analog conversion. Featuring two chips per channel in a fully balanced design, the D3 uses a series of resistor ladders totally unlike the modern-day delta sigma chips found in most DACs.

Top-of-the-line NPC SM5847 digital filter chip

An NPC SM5847 digital filter chip works in tandem with the R2R chips for a truly high-performance audio experience. A 4/8-times oversampling filter, it features independent left and right channel digital deemphasis filters and soft muting function.

16-core USB processor

The VMV D3 implements the XMOS XU216 chip. This 16-core flagship chip enables bit-perfect audio from multiple inputs at sampling rates up to 32-bit/768kHz PCM and DSD512.

Isolated power supply 

The D3’s power supply is isolated in a partially partitioned chassis of its own. This effectively reduces interference and results in an overall cleaner system.

2 ultra-low phase noise crystal oscillators

The D3 uses two Accusilicon ultra-low phase noise crystal oscillators. Offering more precision than regular TCXO clocks, they’re prized for their low power consumption, high resistance to thermal stress, and extremely low jitter.

7 Texas Instruments OPA1612 op amps

Seven dual bipolar-input Texas Instruments op amps help the D3 achieve low noise density with extremely low distortion. Total harmonic distortion + noise for the entire DAC is 0.001%.

All-aluminum remote control

The SMSL VMV D3’s fully functional remote lets you sit back, relax, and have full control over the DAC’s functionality. Buttons for menu, input selection, bluetooth mode, and more let you operate the DAC with the style and convenience of an all-aluminum remote.
