SMSL Continues Its Legacy: D3R vs D2R — A Flagship DAC Upgrade Comparison

SMSL doesn't reinvent the wheel — it refines it. The new D3R builds on the acclaimed VMV D2R with a focused, meaningful upgrade that serious listeners will appreciate.

Introduction

SMSL's VMV series has long been a benchmark for high-end desktop DACs among audiophiles. With the arrival of the SMSL D3R, the brand hasn't torn up the blueprint — instead, it has made precise, purposeful improvements to an already accomplished platform. If you're weighing up whether to upgrade from the D2R, or choosing between the two for the first time, this comparison is for you.

The Core Upgrade: Single Chip to Dual Chip

The D2R's ROHM BD34301EKV is already a highly regarded DAC chip — natural, musical, and analogue in character. The D3R takes this further with a dual ROHM BD34302EKV configuration, and the implications go well beyond a simple chip swap.

A dual-chip architecture means:

• Lower noise floor — each chip handles a dedicated channel, eliminating crosstalk at the source
• Superior channel separation — stereo imaging becomes more precise, with cleaner boundaries between left and right
• Greater dynamic headroom — complex orchestral passages and dense electronic music are rendered with more composure and layering

This is the most substantive sonic upgrade the D3R brings over the D2R, and for listeners who prioritise resolution and spatial accuracy, it is a meaningful step forward.

Where the D2R Still Leads: Feature Depth

The D2R is not outclassed in every dimension. It retains several capabilities the D3R does not offer:

• MQA-CD Decoding — essential for Tidal subscribers and MQA format enthusiasts
• I2S Input — enables direct connection to DDC devices such as the Gustard U18 or SMSL PO100 series, bypassing USB for theoretically cleaner digital transmission
• Remote Control — a practical convenience for daily listening
• APTX-HD Bluetooth — higher-quality wireless streaming compared to standard Bluetooth

If your system is built around MQA or an I2S-connected DDC front end, the D2R remains a highly competitive choice.

The D3R's Philosophy: Pure Decoding, No Compromise

The D3R takes a more focused approach — stripping back features to concentrate entirely on analogue output quality. The dual-chip architecture combined with fully balanced XLR outputs and an all-metal chassis with excellent RF shielding makes the D3R a true reference-grade decoder.

It is the right choice for:

• Listeners whose libraries are primarily PCM or DSD local files
• Users with a high-quality DDC or network streamer as their front end
• Audiophiles building a fully balanced system with a premium headphone amplifier or preamplifier
• Those who prioritise the absolute ceiling of analogue performance over feature breadth

Should You Upgrade?

Your Situation	Recommendation
Heavy MQA user	Stay with D2R
Using an I2S DDC front end	D2R is better suited
PCM / DSD local playback focused	D3R is a clear upgrade
Seeking maximum channel separation and dynamics	D3R delivers a meaningful improvement
Building a fully balanced high-end system	D3R without question

Conclusion

With the D3R, SMSL demonstrates that a great product line doesn't need to be reinvented — it needs to be evolved with intention. The dual ROHM BD34302EKV chips raise the resolution ceiling meaningfully, while the D2R continues to serve listeners who value its broader feature set. Together, they represent the full breadth of SMSL's flagship DAC vision.

Whether you're upgrading or starting fresh, both deserve serious consideration — and we're here to help you choose the right one for your system.
