Choosing a DAC starts with the system around it.
A conventional desktop converter, a streaming DAC, a portable Bluetooth DAC and a combined DAC/headphone amplifier may all perform digital-to-analog conversion, but they solve very different problems.
Inputs, outputs, volume control, headphone support and network integration are therefore more useful selection criteria than headline format limits alone. Our recommendations cover several distinct approaches. The Shanling SM1.3R combines R2R conversion with an integrated streaming platform, while the SMSL SU-2 concentrates on straightforward balanced desktop operation. Models such as the FiiO K17 and Topping DX9 Discrete integrate headphone amplification, and the FiiO BTR17 brings Bluetooth and USB conversion to a portable design. One important exception is the Schiit Audio Eitr 2. It is a digital-to-digital converter rather than a DAC, so it does not produce an analog output. It belongs here only as a specialist option for listeners who need to convert a USB source into coaxial, AES/EBU or optical digital audio before feeding a separate DAC.
1. Shanling SM1.3R R2R DAC: A More Analog Take on Streaming with Roon, Tidal & Qobuz
The Shanling SM1.3R combines a 5.8-inch touchscreen, network streaming platform and proprietary R2R conversion in one component.
The Shanling SM1.3R is the most self-contained streaming choice in this selection.
Its proprietary 24-bit R2R conversion module uses 212 resistors specified to 0.01 percent accuracy, replacing the delta-sigma architecture of the related SM1.3.
A 5.8-inch touchscreen and closed Android-based platform provide access to Roon Ready operation, Tidal Connect, Qobuz Connect and Spotify Connect, alongside dedicated services including Apple Music, Apple Classical and Amazon Music. The closed software environment prevents app sideloading and Google Play Store installation, so buyers should confirm that the supplied services cover their needs.
Best for: An integrated R2R streaming system
- Proprietary 24-bit R2R conversion module
- Roon Ready with major Connect services
- Integrated 5.8-inch touchscreen
- Internal SSD slot for local playback
Verdict: Choose the SM1.3R when built-in streaming, touchscreen control and R2R conversion matter more than installing additional Android apps.

The compact Schiit Audio Eitr 2 converts USB audio into coaxial, AES/EBU or optical digital signals for a separate DAC.
The Schiit Audio Eitr 2 needs a clear distinction: it is a digital-to-digital converter, not a digital-to-analog converter.
It accepts USB audio from computers, tablets and smartphones, then regenerates that input for delivery to a separate DAC.
Outputs include transformer-isolated coaxial, AES/EBU and optical, with the optical connection supporting PCM up to 24-bit/192 kHz. Schiit’s proprietary Unison USB interface is intended to manage signal integrity at the USB stage. The Eitr 2 is relevant only when a system already has a DAC but needs a different digital connection or an intermediary between the USB source and converter.
Best for: Feeding a separate DAC from a USB source
- Converts USB audio to three digital output types
- Transformer-isolated coaxial output
- AES/EBU and optical outputs
- Optical PCM support up to 24-bit/192 kHz
Verdict: Consider the Eitr 2 as a specialist USB bridge, not as a replacement for a DAC with analog outputs.
6. SMSL SU-2: A Compact, Balanced DAC Built for Serious Desktop Audio
The compact SMSL SU-2 uses LED status indicators and supplies both balanced XLR and unbalanced RCA outputs.
The SMSL SU-2 takes a deliberately focused approach to desktop conversion.
It uses an ES9039Q2M DAC chip with four OPA1612A operational amplifiers arranged symmetrically across the left and right channels.
Balanced XLR and unbalanced RCA outputs allow it to serve active monitors, balanced amplifiers or conventional RCA-based systems. The solid metal chassis is compact, and operation is handled without a display or menu system; LED indicators provide status information instead. That simplicity makes it appealing where predictable integration and a small footprint take priority over elaborate front-panel controls.
Best for: Balanced desktop systems and active monitors
- Fully balanced signal path
- Balanced XLR and unbalanced RCA outputs
- Compact solid-metal chassis
- Simple LED-based operation without menus
Verdict: The SU-2 is the focused choice for a compact desktop system that needs balanced outputs without a display or menu structure.
7. Cinnamon Galle: Might be the most unique DAC you have ever seen
The Cinnamon Galle houses its dual-mono resistor-ladder conversion system in a cast bronze and aluminum alloy enclosure.
The Cinnamon Galle stands apart through both its conversion architecture and physical construction.
Rather than using an off-the-shelf DAC chip, it employs a quasi-non-oversampling design with additional signal processing and a dual-mono, 27-bit differential resistor ladder.
That ladder comprises 430 precision resistors specified to a tolerance of 0.01 percent. The bronze and aluminum alloy enclosure is minimally processed after casting, so variations in surface texture and appearance are an intentional part of the design. USB supports DSD256 and PCM up to 24-bit/384 kHz, while the RCA S/PDIF input supports PCM up to 24-bit/192 kHz.
Best for: Distinctive resistor-ladder design and craftsmanship

Frequently asked questions
Should I buy a standalone DAC or a DAC/headphone amplifier?
Choose a standalone DAC when you already have an amplifier, active speakers or a separate headphone amplifier.
A combined unit such as the FiiO K17, FiiO BTR17 or Topping DX9 Discrete is more appropriate when the DAC must also drive headphones.
Do balanced XLR outputs matter?
Balanced outputs are useful when your amplifier or active monitors accept XLR connections, particularly in desktop, studio or longer-cable installations.
The SMSL RAW Pro-DAC1 and SU-2 provide XLR and RCA outputs, allowing either connection type; balanced outputs provide no practical advantage if the receiving equipment accepts only RCA.
Should maximum PCM and DSD rates determine the purchase?
Not by themselves.
Confirm that the DAC supports the formats your sources actually deliver, then prioritize suitable inputs, analog outputs, volume control and system role.
Very high format ceilings are irrelevant if your transport, streamer or music library never uses them.
Is a digital-to-digital converter the same as a DAC?
No.
A DAC creates an analog signal for an amplifier or active speakers.
A DDC such as the Schiit Audio Eitr 2 changes one digital connection into another and still requires a separate DAC downstream.
How to Choose the Right DAC for Your System
Begin with the source.
Network listeners who want services and local playback in one chassis should consider the Shanling SM1.3R, while computer-based systems can use a simpler USB-equipped desktop DAC.
The FiiO BTR17 is better aligned with phones, portable headphones and mixed Bluetooth/USB use, and the Schiit Eitr 2 is relevant only when USB must be converted before reaching an existing DAC. Next, match the analog side of the system. Active monitors and balanced amplifiers make the XLR-equipped SMSL RAW Pro-DAC1 and SU-2 especially practical. Headphone users should distinguish between a standalone DAC and an integrated DAC/amp: the FiiO K17 and Topping DX9 Discrete are desktop all-in-ones, while the BTR17 addresses portable headphones. Where demanding headphones are involved, supported amplifier output and volume-control behavior deserve more attention than conversion format limits. Finally, decide how much complexity is useful. The SU-2 deliberately avoids displays and menus, whereas the Shanling SM1.3R provides a touchscreen streaming environment. The Cinnamon Galle prioritizes a specialist resistor-ladder architecture and distinctive construction, while the VMV D2R MK2 emphasizes ROHM conversion and OCXO clocking. Select the product whose inputs, outputs and operating style fit the equipment you already own rather than paying for formats or functions that will remain unused.
