Amplifiers
DACs and amplifiers optimise audio output for headphones and headsets by converting audio signals, amplifying them, or combining both functions.

DACs and Amplifiers for Your Audio Setup
DACs and amplifiers expand your setup with additional audio connections and provide the appropriate power for headphones and headsets. Many models combine both functions in a compact device and offer easily accessible controls for gaming, music, and voice communication.
DAC, Amplifier, or Combination Device?
| Product Type | Function | Suitable For |
|---|---|---|
| DAC | Converts digital audio signals into analogue signals | Setups with an existing amplifier or active audio devices |
| Headphone Amplifier | Amplifies an existing analogue audio signal | Headphones that cannot be driven sufficiently by the existing output |
| DAC Amplifier | Combines signal conversion and amplification | Compact all-in-one solution for PCs, laptops, or consoles |
When Is a DAC or Amplifier Useful?
A DAC or amplifier can be useful if your device does not offer a suitable audio output, if you experience unwanted noise, or if your headphones are not loud enough. Additional connections, more power reserves, and easily accessible controls can also be reasons to use an external audio device.
What Is the Difference Compared to an Audio Interface?
An audio interface combines audio output with additional inputs for recording. Many models offer XLR or jack inputs for microphones and instruments as well as an integrated headphone output. This makes them particularly suitable for streaming, podcasts, music production, and other recording applications.
If you mainly want to connect headphones or headsets and improve your PC's audio output, a DAC or DAC amplifier is often the more suitable solution. An audio interface, on the other hand, is particularly useful if you also want to connect a microphone or instrument via XLR or jack, for example for streaming, podcasts, or music recording.
If you also need a microphone input, multi-channel outputs, or specific features for gaming and voice communication, a sound card may be the more suitable solution.
FAQ – DACs and Amplifiers
What Is the Difference Between a DAC and an Amplifier?
A DAC converts digital audio signals into analogue signals. An amplifier increases the power of the analogue signal so that connected headphones can be driven at a sufficient volume.
Do I Need a DAC and an Amplifier?
Not always. If your device already has a suitable DAC or a sufficiently powerful headphone output, a single component may be enough. A DAC amplifier combines both functions in one device.
When Do Headphones Need an Amplifier?
A headphone amplifier can be useful if the headphones are too quiet when connected to the existing output or are not driven sufficiently. In addition to impedance, the sensitivity of the headphones and the output power of the audio device are also relevant.
Can I Use a DAC Amplifier with a Games Console?
This depends on the model and console. Before buying, check whether the DAC amplifier supports the console and its USB audio output or another available digital connection.
Can I Connect Active Speakers to a DAC?
Yes, if the DAC has a suitable analogue output. Passive speakers, however, require a suitable speaker amplifier and cannot be connected directly to every DAC or headphone amplifier.
Does a DAC Automatically Improve Sound Quality?
Not automatically. The result depends on the existing audio output, the DAC, the amplifier, and the connected headphones or audio devices. Additional connections and low-noise signal processing can still provide benefits.
