AudioQuest Dragonfly — Best Headphone Amp DAC Combo

AudioQuest Dragonfly

For those who like to listen to high-quality music on the go, this small device might become the best headphone amp DAC. It’s compact and easy-to-use, improves your sound considerably with regard to the direct PC / smartphone playback, and looks good, too. The compact design, however, doesn’t leave room for controls — there are none onboard.

The size of this model is 0.74 x 0.47 x 2.24 inches, its weight is 4.2oz. It has a USB Type-A connector and is supplied with the Type-C adaptor. The adaptor is short and sturdy and doesn’t bring in jitter or noise. On another end, the unit has a standard 3.5mm jack for headphones.

The DAC part of this model works well with almost any type of sound file. It can process them with up to 24/96 kHz resolution and amplifies well. I enjoyed the improved MP3 performance with a more accurate main line, cleaner bass and highs. Still, when it came to MQA and ALAC, the difference was yet more obvious. There’s plenty of detail, and the integrated slow roll-off and minimum phase filters make audio neutral, without an accent on any particular frequency range.

This DAC amp combo is equipped with 64-bit volume control offering a sensitive detailed response. The sound gets loud without distortion up to high levels.


  • Advanced Microchip provides for a small current draw and 2.1V output.
  • Compatible with Windows, Android, iOS, Linux devices.
  • The Dragonfly insert changes color with regard to the frequency played and the status of work.


  • Connected to iPhone, the headphones controls and mic don’t work.
  • Sounds a bit tight in the highs.

FiiO E10K — Best DAC Amp Combo under $100

FiiO E10K

This inexpensive portable combo unit offers a variety of controls and inputs, and works with Hi-Res files at 24/96 kHz resolution. It certainly deserves a place on your best DAC amp under 100 list for its advanced design and considerable output. The only caution I’d put is that the unit provides a warm sound; so, if you need the “dry” studio-quality audio, it mightn’t fit.

The DAC amp is compact and has a smooth finish, rounded corners without sharp edges. The casing is made of aluminum accounting for a small weight (just 2.72oz). The device would fit in half of your palm being 3.11 x 1.93 x 0.83 inches big.

The power output of this amp makes 10W, and it’s compatible with headphones ranging from 16 to 150 Ohms. The amplifier and DAC are powered by different chips making the output clear and solid. The frequency range makes 20 Hz – 20 kHz, and the unit draws a detailed soundstage with the distinct ranges. There are also several technologies implemented to boost the low-end of your audio: the low-pass filter, bass boost technology bring the powerful and non-muffled bass played from any device.

The Fiio e10K setup is simple. Plug in your headphones into the front 3.5mm jack, connect the source via the micro USB, select the volume and desirable bass level, and you’re good to go. There’s also a coaxial output and Line Out jack, letting you connect the active speakers as well.


  • The sensitivity of 108 dB allows you to increase the volume without losing sound clarity.
  • The USB port works for power as well.
  • The volume knob has a blue LED light, which is convenient to use in the dark.


  • Sounds a bit flat on complex music like R&B or Acid Rock.
  • The supplied micro USB cable is short and isn’t convenient to use with the PC.

Sound Blaster G6 — Best DAC Amp Combo under $200

Sound Blaster G6

Built on the basis of the USB sound card, the G6 model integrates the high-resolution DAC (32-bit and 384 kHz frequency) and a powerful low-impedance (1-Ohm) amplifier. With the high sensitivity of 130 dB, it probably makes the best DAC amp combo for gamers. However, when using the DAC at the highest sampling speed, it might occasionally provide clicks and hisses before the audio playback.

The amp DAC is designed primarily for gaming, and as such it has separate inputs for headphones and the mic. The amplifier can drive the headphones and headsets from 16 to 600 Ohms providing a lot of detail and balance to the audio output. The voices and effects sound distinct, and the smart processor filters the background sounds giving preference to the voices (the Scout mode). The unit is compatible with gaming consoles, as well as with a variety of AV sources.

The box isn’t the smallest, it’s 4.37-inch long, 2.76-inch wide, and 0.94-inch tall. It weighs 7.1oz and has 2 inputs (headphones and mic) on the front, with the volume dial in between. On the back panel, there is a ⅛-inch Line In port and ⅛-inch Line out, and the micro USB with bus-powered functionality.

The audio formats supported include Dolby Digital and 5.1- and 7.1-surround sound formats providing the immersive soundstage with high-class separation. This makes this USB DAC amp suitable for gaming, movie watching, and music listening.


  • The amplifier works in the bi-amp mode amplifying each headphone channel separately for high clarity.

Buyer’s Guide

Do you need a dac amp combo?

A DAC amp is an external device that combines two pieces of acoustic gear: the digital-to-analog converter and the amplifier. The same devices, but of a smaller size and quality, are integrated into all electronic devices dealing with digital signals and their output to speakers and headphones. They transform the digital signal to analog and then amplify it so that it could be received and reproduced by the acoustic drivers.

So, why would you need an external combo device? There are the following reasons:

  • Better sound quality. The external DAC/amp usually packs much more power and the more developed DAC chips. This results in a more detailed and natural sound output. Still, any part of the chain “initial sound – listener” might let you down. In case you have a bad recording, a weak source, or low-quality headphones, the amp/DAC alone won’t help much.
  • More control over your sound. Many DAC/amp combined units provide a more detailed volume control, low-pass filter, minimum phase, slow/ sharp roll-off, and other filters. The EQ functionality might be also integrated
  • An input from / output to different devices. Many combo devices of the amp/DAC let you plug in the different headphones jacks and RCA ports. Meanwhile, you might also need a device that can connect to a TV, a CD player, a PC, and provide improved audio playback from these sources.

Features You Need to Consider Choosing a DAC Amp Combo


For the majority of the everyday tasks, you might do well with a single USB input on your DAC/amp. However, if you plan on upgrading the sound from/on the different devices, it’s wise to take an amp/DAC with several inputs. The most frequent ones installed in the amp/DAC combo devices are headphones jack (3.5mm, 6.3mm), dual RCA ports, USB, coaxial and optical connectors. Some also support Bluetooth connection.

Sampling Rate

The sampling rate is important, as it shows the number of times per second that the device scans (gets samples) from the digital signal. For example, the 192 kHz rate means the DAC/amp gets a sample 192,000 times per second. Some of the devices can reach a 768 kHz sampling rate. The received data is transformed into an analog signal. The higher the number, the more accurate, rich, and jitter-free the analog output will be


With regard to the acoustic gear, the impedance means the amount of power this device needs to work properly (e.g. 6 Ohms, 32 Ohms, 200 Ohms for headphones). This number also shows how much power it would take to disrupt such a signal. The devices with the higher impedance are considered more demanding, yet safer as well. The higher the impedance of the headphones, the less is the risk of overloading the other components of the setup.


Compatibility is important, as it means you can use the DAC/amp device with different types of gear. List the devices you are going to hook up to the combo device. These can be a PC, a smartphone, a DVD player, and so on. Then, examine the connectivity, technical parameters, software compatibility. It might turn out that the amp / DAC doesn’t work with a certain device (i.e. a tape player) or doesn’t support certain OS versions (e.g. Windows XP).


Many of the modern DAC/amp combined devices are quite compact (some are no more than 4 inches in length) and lightweight (less than 1lb). That makes them well portable. Another parameter affecting the portability is the number of cords necessary for the amp/DAC to work. Some models integrate a battery that can recharge via the USB connection or through the power plug. Some also support Bluetooth.
