A good DAC is not just a format converter.
It is the digital hub that decides how cleanly a streamer, computer, disc transport, or other digital source becomes an analogue signal your amplifier can use.
The most useful choice is rarely the most complicated one; it is the DAC that matches your sources, system layout, preferred control style, and appetite for features.
1. Review: Shanling EH2 – A High-Value R2R DAC/Amp That Bridges the Gap
Shanling EH2, a compact desktop DAC/amp built around a proprietary 24-bit R2R ladder DAC.
The Shanling EH2 is presented as the missing middle model between Shanling’s simpler EH1 and the more feature-laden EH3.
Its defining feature is a proprietary 24-bit R2R ladder DAC, giving it a distinct architectural identity in a compact desktop DAC/amp format.
The source frames it as a step up from basic entry-level functionality without making the jump to a flagship-grade device, which makes its appeal especially clear for listeners who want a more serious desktop unit but do not need every top-tier feature Shanling offers.
Best for: Desktop listeners who want an approachable R2R DAC/amp
- Proprietary 24-bit R2R ladder DAC
- Desktop DAC/amp format
- Positioned between the EH1 and EH3
- Hi-Res and Hi-Res Wireless certification noted
Verdict: The Shanling EH2 is the most natural pick here for a compact DAC/amp that brings R2R conversion into a practical middle-ground product.
2. Denafrips Enyo: R2R DAC that supports high-resolution audio streams
Denafrips Enyo, a balanced R2R DAC with USB, coaxial, optical, RCA, and XLR connectivity.
The Denafrips Enyo is a balanced R2R DAC aimed at listeners who want broad high-resolution support and a more configurable digital front end.
The source highlights PCM support up to 24-bit/1536 kHz over USB and DSD up to DSD1024, while optical and coaxial inputs support PCM up to 24-bit/192 kHz and DSD64 via DoP.
Its R2R implementation uses precisely matched resistors, with each channel decoded by four sets of R2R networks, and it gives users NOS or oversampling operation plus slow or sharp filter options.
Best for: Systems needing balanced analogue output and broad digital format support
- Balanced R2R DAC design
- USB supports PCM up to 24-bit/1536 kHz and DSD1024
- NOS and oversampling modes
- RCA and balanced XLR outputs
Verdict: The Denafrips Enyo stands out for combining R2R conversion, flexible filtering, and extensive high-resolution compatibility in a dedicated DAC.
3. Atoll DAC200 Signature: Classic digital-to-analog converter
Atoll DAC200 Signature, a full-size external DAC with balanced circuitry and an aluminum front panel.
The Atoll DAC200 Signature takes a more traditional full-size hi-fi approach, with balanced circuitry, twelve independent voltage regulators, and two linear transformers supplying the output stages.
Its discrete output stages operate in Class A without feedback, and the design uses selected components including silver-plated mica capacitors and MKP capacitors.
Digital conversion is handled by an ESS SABRE ES9028PRO chip supporting PCM up to 32-bit/768 kHz and DSD up to DSD512, with a precision clock generator for low jitter and filter control available to the user.
Best for: Full-size hi-fi systems that value robust power supply design and flexible control
- Balanced circuitry
- ESS SABRE ES9028PRO converter chip
- PCM up to 32-bit/768 kHz and DSD512 support
- Switchable volume control from front panel or remote
Verdict: The Atoll DAC200 Signature is the strongest fit for a conventional component system where build, power supply design, balanced circuitry, and format support all matter.
Frequently asked questions
Should I choose an R2R DAC or a chip-based DAC?
Neither approach is automatically better for every system.
The Shanling EH2 and Denafrips Enyo use R2R ladder conversion, while the Atoll DAC200 Signature uses an ESS SABRE ES9028PRO chip.
Treat the architecture as one part of the decision, then compare inputs, outputs, supported formats, control options, and how the unit will fit into your system.
Which inputs matter most when buying a DAC?
Start with the sources you already use.
USB is often important for a computer or streamer, while optical and coaxial inputs suit many transports, televisions, and digital components.
The Denafrips Enyo is a good example of a DAC with USB, coaxial, and optical input options, so it suits systems with several digital sources.
Do I need balanced XLR outputs?
Balanced XLR outputs are useful if your amplifier or active speakers accept them, especially in a system already wired around balanced connections.
The Denafrips Enyo includes RCA and balanced XLR outputs, and the Atoll DAC200 Signature is described with balanced circuitry.
If your amplifier only has RCA inputs, balanced output is not essential.
How much should high-resolution format support influence the choice?
Format support matters most when your music library or playback software actually uses those formats.
The Denafrips Enyo lists very high USB support for PCM and DSD, and the Atoll DAC200 Signature also supports high-rate PCM and DSD.
If you mainly use standard-resolution streaming or optical/coaxial sources, connection quality and system matching may matter more than the highest possible numbers.
How to choose the right DAC for the long term
Begin with the role the DAC must play.
If the system is a desk setup and you want one compact unit that handles conversion and headphone or amp duties, the Shanling EH2 is the most relevant of these three because it is specifically framed as a desktop DAC/amp with a proprietary 24-bit R2R ladder DAC.
It is also positioned between Shanling’s entry-level and flagship-style options, which makes it a sensible middle-ground choice rather than a specialist component with unnecessary complexity.
