Frequently asked questions
Should I choose a desktop DAC or a portable DAC/amp?
Choose a desktop model if you need more connection options, a fixed hi-fi setup, or a more substantial headphone station.
The FiiO K13 R2R, iFi Zen Dac 3, LOXJIE D30, Shanling EH3, Accuphase DC-37, and Denafrips Terminator II 12Th all suit stationary use in different ways.
Choose a portable model such as the Astell&Kern AK HC5, HiBy Digital D1, FiiO BTR13, or Shanling H0 when phone, laptop, or travel use is the priority.
When does balanced output matter?
Balanced output is useful when your headphones, amplifier, or active-speaker setup supports it and you want to use the matching connection.
Several products here provide balanced options, including the FiiO K13 R2R, iFi Zen Dac 3, Denafrips Terminator II 12Th, FiiO BTR13, and Shanling H0.
If your system only uses standard 3.5 mm headphones or RCA inputs, balanced output should not be the deciding factor.
Are Bluetooth DACs a replacement for USB or wired digital inputs?
Bluetooth adds convenience, especially on the FiiO K13 R2R, LOXJIE D30, Shanling EH3, and FiiO BTR13, but wired USB or dedicated digital inputs are usually the more direct choice for a fixed system or high-resolution file playback.
The right choice depends on whether convenience, source flexibility, or a stable wired connection matters most in your setup.
Do I need R2R, ESS, Cirrus Logic, or another specific DAC design?
Chip or conversion type can guide your shortlist, but it should not be the only criterion.
The FiiO K13 R2R and Denafrips Terminator II 12Th emphasize R2R conversion, the LOXJIE D30 and Shanling EH3 use ESS-based platforms, and the HiBy Digital D1, FiiO BTR13, and Shanling H0 use Cirrus Logic DAC chips.
Match the device first to your connections, headphone needs, source devices, and control preferences.
How to choose the right DAC from this list
Start with the system you actually use.
If the DAC will live in a full hi-fi rack, the Accuphase DC-37 and Denafrips Terminator II 12Th are the clearest component-level choices, with the Denafrips placing particular emphasis on balanced R2R NOS conversion, extensive digital inputs, and clock connectivity, while the Accuphase focuses on proprietary DSD processing, HS-LINK, and heavily separated analogue and digital construction.
For a desktop headphone system, the FiiO K13 R2R is the most configurable option thanks to R2R conversion, NOS/OS modes, Bluetooth, PEQ, and substantial stated headphone power. The iFi Zen Dac 3 is more compact and computer-oriented, while the LOXJIE D30 adds Bluetooth, ESS conversion, MQA decoding, and broad high-resolution support. The Shanling EH3 is the better fit when wireless network playback, Bluetooth receiver use, and I2S pairing with Shanling’s ET3 are central to the system. If portability matters, narrow the field by how you connect. The Astell&Kern AK HC5 is the most premium-positioned USB dongle in the supplied material, built around Astell&Kern’s AK4499EX and AK4191EQ architecture. The HiBy Digital D1 is a simpler compact DAC/amp for wired headphones and mobile or PC use, with practical volume controls and low power consumption. The FiiO BTR13 is the most flexible small device for switching between PC, Bluetooth, and phone roles, while the Shanling H0 is a compact USB DAC/amp with balanced output, gain settings, and wide format support. The safest buying decision is to prioritize the connections you need, the headphone outputs you will actually use, and the source devices you listen from every day before comparing conversion architecture or format support.
