Best DAC/Amp Combo

The continuous evolution of technology always intends to do better. When you are involved in the audio world, you will realize there are more than high-end speakers or headphones. The audio source needs to be passed through a DAC/Amp so that you listen to the audio without losing quality or eliminating external noise.

DAC is built-in in Laptop, soundcard, mobile, or headphone, then why do we need an additional DAC/Amp? The reason is the quality of the built-in DAC isn’t always good and it can’t avoid the unwanted noise inserted by the source into the sound.

If you have a DAC/Amp, it will ensure that you hear audio with clarity. You can also get standalone DAC or Amp but here we will talk about DAC/Amp Combo. This article will focus on some of the best DAC/Amps with different features and different price ranges.

What is the function of a DAC and an Amp?

The audio sources store soundtracks in digital format that is, 1s and 0s. The purpose of a Digital-to-Analog Converter or DAC is to convert the digital signal to analog signals so that we can listen to music. You can connect it to the audio source by USB, Coax-SPDIF, or Fibre-SPDIF.

Once the conversion is complete, the purpose of Amp is to amplify the low voltage analog signal and pass it to the device with which you will listen to music (headphones, speakers, etc.). Speaker amps are powerful than headphone amps which can deliver 100W or more. Headphone amps generally give one or two watts of power.

What does a DAC/Amp do?

DAC/Amp as the name suggests works both as a DAC and an amplifier. If you have this single device, then you don’t need two separate devices for DAC and amplification of your signal. There are different kinds of DAC/Amps, Desktop DAC/Amps, or portable DAC/Amps.

Why do you need one?

Is it a must to have a DAC/Amp? Well, not everyone needs a DAC/Amp. If you think your audio source like Computer, Laptop, Smartphone isn’t adding any noise to the audio signal then you don’t need a DAC. However, if they do introduce noise or can’t produce music at the same bitrate as you file you need a DAC and for amplification, and Amp.

The use of DAC/Amp will simply enhance the audio quality of your sound, ensuring you get distinct, clear, and music without external noise. If you have a powerful speaker or headphone that needs more power to run and your audio source can’t provide that power. Then you need an amplifier to feed them so that the audio track can get louder.

Factors that affect the quality of the DAC/Amp:

Streaming service or File size

What is your audio source? It is recommended not to use portable sources like iPad to store audio because they have storage limitations. You can use a PC or Laptop to store lossless audio files with high resolution. While streaming, to enhance the quality of your audio source you can try to shift from Spotify to Tidal, Amazon Music HD, or Qobuz.

Since you are going to spend on an external DAC/Amp, choosing the accurate streaming service or file type is crucial to make a difference. You can keep your files in any of the formats given below:

  • FLAC: this stands for Free Lossless Audio Codec. Although the FLAC has a smaller size, 16bit/44.1kHz, they maintain a high resolution of the audio. It is widely used and also found in Tidal. All DAC/Amps support this file.
  • ALAC: this stands for Apple Lossless Audio Codec. The Apple Music stream deploys this type of file. It has a ‘lossy’ character which means some data and quality is lost from the original source. Unlike FLAC, the sample rate/bit depth is not fixed.
  • Ogg Vorbis: While FLAC is found in Tidal, the Ogg Vorbis belongs to Spotify. They are also lossy in nature like ALAC. Although they have a sample rate of 44.1kHz, they don’t have bit depth. Compared to FLAC the quality is not so good.
  • MQA: Master Quality Authenticated format belongs to Tidal and has high-quality files that has a high sample rate/depth. A ‘fold’ method is used for these files and a DAC/Amp with an ‘unfolding’ nature can decode it.
  • CD: although rarely used, this has a 16-bit/44.1kHz sample rate/depth.

Quality of files

The quality of audio files can be measured by sample rate and bit depth. As stated above a regular audio file like CD has 16bit/44.1kHz. a better and higher file resolution may have specs like 24bit/ 192kHz. While most DACs will work with FLAC/ALAC/MQA, it is suggested to go with the best quality of files for optimum performance of the DAC/Amp.

There are other examples like 32-bit/768kHz, 24bit / 44.1Khz, etc so you need to look for these specs of your audio files and match a DAC/Amp that supports it. While some DAC/Amps can be found for low or medium quality files, like from Spotify, others will support files from Tidal.

Audio source

What is the source with which you want to connect the DAC/Amp? Whether it’s a headphone or a speaker, you need to make sure they are of high quality. Otherwise even after adding a separate DAC/Amp you will not notice any difference.

If you have a high-end system make sure you use a better quality DAC/Amp with advanced features whereas match an entry-level DAC/Amp with an ordinary source. Also, choose the DAC/Amp based on the type of source such as Desktop, Headphone, speaker, smartphone, iPad, iPad, etc. Also read how you can select amps for your speakers

Computer knowledge

Some DAC/Amps need you to install a particular software on your computer. So you should have some level of knowledge regarding how to download and install certain software. Although they will come with instructions, if you are an expert, it will be easier for you to work with the device.


Along with devices, the cables and wires play a huge role and if you want more details you can see  How To Choose Best Speaker Cable. Generally, you should the cables that come with the box such as USB, optical, coaxial, stereo mini, XLR, RCA patch cables.

DAC/Amps are the little inclusion that can make a huge difference in sound quality. Before buying a DAC/Amp look for the features and specifications of it. The build quality, compatibility, supported rate, and files are important factors.

In this article, I have listed some of the famous and best DAC/Amp combos that audiophiles often use. A DAC/Amp will add extra clarity, no-noise, and deliver undistorted audio which otherwise is not possible to hear. if you are new at this, you can always try with an entry-level device at an affordable price range.

While most DAC/Amps have some common features, if you want advanced features like MQA support then you should look for this into the DAC/Amp. If you have a sturdy DAC/Amp that delivers a neutral, natural, and warm sound without coloration of the audio, then it is worth having it.


Still have some questions unanswered? Find out them in this section.

Q: Does DAC/Amp improve audio or is it a myth?

Answer: This depends on the situation. Some audio sources might not need a DAC/Amp. If you can’t hear any hissing sound or you hear audio with extreme clarity and loudness, then you don’t need it. However, DAC/Amp is not a myth. If you can choose correctly, then it will provide a noticeable difference in the audio.

Q: If I listen to Tidal, which DAC/Amp should I get?

Even if you don’t listen to Tidal, you should do it. This is because DAC/Amps always encourage us to listen to high-quality music so that they can effectively perform the conversion. However, if you listen to Tidal, then you must look at whether the DAC/Amp supports MQA. Because this feature is not available on all devices.

Q: Can I only use the DAC instead of a DAC/Amp?

You can use a DAC without a DAC/Amp because a DAC/Amp is not mandatory. If you think you have powerful headphones or any audio source that delivers audio with optimum loudness, then you don’t need an amp.
