Best DAC Amp Combo Reviews

A DAC amp combo is exactly what it sounds like. Usually, they are a combination of a DAC and a headphone amp. In other words, this is a DAC with a built-in headphone amplifier.

In all DAC amp combos, an amp is designed specifically for headphones. If the amp is needed for speakers, then you should look towards AV receivers.

A digital amplifier is really a DAC with a higher voltage level to some degree. The way they achieve that is dependent on the design.

The DAC takes a digital bitstream and uses either a resistor ladder or Delta-Sigma accumulator to convert digital numbers (16-bit, 24-bit, or even 32-bit) at a given rate (44.1KHz, 48KHz, 88.2KHz, 96KHz or multiples) and builds an analog signal from 0-2v for consumer equipment.

The digital amp is built to take a digital input stream and create a high-level signal that is suitable to drive speakers directly. There are a couple of different architectures to do this. One of the most interesting is the one developed by NAD, which is essentially a switched-mode amplifier that takes in the digital signal and amplifies it to a high-level pulse signal and then uses output filters to smooth the resulting waveform.

In the article, the goods are divided into price groups for the convenience of choice. However, if you don’t know what device you need, then pay attention to the “under 200” category. Gadgets from there are perfect for buyers with a limited budget and a desire to start somewhere.

FX Audio DAC-X6 – best under $100

FX Audio DAC-X6

DAC-X6 is a low-cost device that is a USB DAC that can operate as a computer sound card, receive and process digital OTG signals from a smartphone, and also play a signal received via optical and coaxial inputs. Also, from the output interfaces are available, a headphone and two channels “R” and “L” for acoustics.

The DAC-X6 has a pretty good chipset. So, the chips are responsible for sound processing: CS8416 + CS4398 (the same is installed in Fiio x3 – 2, as well as xDuoo x3) + OPA213, for the amplifier part: OP275 + TPA6120 chips.

The best DAC amp under $100 is made of metal, the assembly is high-quality, without complaints. Size and weight are surprising. This toy is not one of the smallest.

DAC-X6 has a set of connectors – both USB and optical and coaxial connectors. This allows you to connect not only a computer but also a TV, console, or CD! The source is selected by the switch.

DAC-X6 supports sound in the so-called dense – up to 14 bit / 192 kHz via both USB and optical connectors. The USB connection is compatible with UAC1 and does not require the installation of additional drivers – it is directly supported by all modern operating systems supporting USB Audio Class 1.0. The DAC device is used in the production of CS4398 from Cirrus Logic. The SPDIF receiver comes from the same company. This is CS8416. The VT1630A chip produced by VIA is responsible for the operation of the USB connector.


  • The music in 24/96 and 24/192 sounds magical, and if in optics, in general, an immersive atmosphere is created
  • The low-frequency range is very well worked out
  • Does not heat up during playback


  • Windows volume control does not work. You can only turn off the sound completely

FiiO Q1 Mark II

FiiO Q1 Mark II

The Fiio Q1 Mark II DAC supports PCM up to 384 kHz/32 bit. It comes with a built-in DSD256 level decoder, discrete dual crystal oscillators for different sampling rates, and perfectly accurate digital-to-analog conversion. In addition to the line input/output jack, this FiiO device offers a single-headed 3.5 mm headphone jack and a 2.5 mm balanced headphone jack. The 3.5 mm headphone output works with many standard letters, while the 2.5 mm output works with balanced headphones. On the right side of the appliance, you will find two LED lights. When the first one is on, it means DSD decoding is active, while the second one indicates the power is on.

Instead of drawing power from your smartphone, FiiO has supplied this DAC with a 1800mA battery that claims to last an average of ten hours. The model feels great to hold, however, the large volume knob means that you can’t use it when the appliance is lying on a surface since the dial makes contact with the surface.


  • Well-balanced frequency range – tinkling highs come without an undue sharpness
  • Comes in an all-metal shell of the original Q1 with an anodized sandblasted finish to the outer shell for easier gripping
  • In high-gain mode, the Fiio Q1 Mark II can drive high impedance headphones, and the bass adjustment mode will help you enjoy all genres of music


  • On a Windows laptop or desktop, a driver needs to be installed before you can use the device as a DAC
  • No wireless functions

Topping DX3 Pro – best under $200

Topping DX3 Pro

This is a desktop stationary DAC/amp combo for use with headphones or active monitors. It supports all modern audio formats, in the resolution of PCM 32/768 and DSD, although the manufacturer does not specify to what sampling rate. If you consider, the DX3 Pro runs on two AK4493, which easily supports the DSD512, so let’s take a word. Moreover, the combo produces 1000 mW (32 Ohm) or 125 mW (300 Ohm) at the headphone output.

In addition to two AK4493 chips, the combo is equipped with OPA1612 and XMOS U208 USB interface operational amplifiers. The OPA1612 operational amplifier offers high accuracy and low harmonic distortion. The latter is illustrated by very low electronic noise (1.1 nV / √Hz) and distortion (0.000015% at 1 kHz). This opamp model offers, first of all, an output signal of 600 mV at a load of 2 kΩ, so it can handle most modern headphones, offering controlled dynamics, a stable gain, and an ideal power reserve to bring you all the spatial depth of high-resolution music.

Qualcomm’s CSR8675 chip gave the device the fifth generation of Bluetooth and low power consumption. Also, the V2 version began to support the Bluetooth codecs Apt-x HD and LDAC.


  • You will be glad to see a decent remote control (with a good CR2032 battery)
  • The headphone amp is incredibly powerful


  • The disadvantage is expressed primarily in inconvenient control, which is partially offset by the presence of remote control

  • Compatible with all iOS versions
  • Linear frequency response, extended on both ends


  • Aging micro-USB port
  • Comes with waw aluminum edges that are prone to scratches

Cambridge Audio Azur DacMagic Plus

Cambridge Audio Azur DacMagic Plus

Released more than five years ago, Cambridge Audio’s DacMagic digital-to-analog converter was recently replaced with a more modern version with the Plus prefix. It has improved the USB interface, added support for the Bluetooth module, and a built-in amplifier with higher characteristics. This modernization made this unit a candidate to be the best amp DAC combo on the market.

The best DAC amp combo in this group is based on a pair of 24-bit Wolfson WM8740 converters, which, despite their considerable age, have very high characteristics. The rest of the “positive” DAC significantly surpasses the functionality of the usual DacMagic. The parameters of the USB interface have been upgraded to specifications 2.0, and now it supports asynchronous audio data stream with a resolution of up to 24 bit / 192 kHz. An optional USB port allows you to connect the BT100 Bluetooth module, compatible with the AptX codec. For digital filtering (according to the patented algorithms of Anagram Technologies) with three switchable modes, the Analog Devices ADSP21261 processor is responsible for upsampling the input data to 24 bits / 384 kHz. And the opportunity to adjust the level at the analog outputs – normal and balanced – turns this small box into a fully functional digital preamplifier serving up to four sources.


  • By and large, DacMagic Plus appealed to me with switchable digital inputs and a good amplifier for headphones
  • Interestingly, the cascade with volume control can be disabled


  • The upsampling off button and the remote control would still not hurt

Marantz HD-DAC1

Marantz HD-DAC1
Like all models in the article, this is a digital-to-analog converter and preamplifier in one bottle, offering outputs with both a fixed signal level and a variable one, which allows the user to choose the option that suits them. It is also worth noting that there are no XLR outputs.

In terms of other functions – everything is much better. On board of the best USB DAC amp in the reviewed segment, there are four digital inputs, one of which is coaxial, the other two are optical, and there is also USB-B. DAC supports all modern formats, including DSD128. Unlike other models in the review, this one has an analog input of 3.5 mm, as well as the ability to connect iOS devices via USB on the front panel, which makes it even more convenient to use. This device is also designed to work as a headphone amplifier capable of handling loads of up to 600 ohms. Supported PCM formats 44.1-192 kHz, DSD64 / 128.

The design of the HD-DAC1 evokes mixed feelings. The round display surrounded by symmetrical control knobs is easy to use and elegant. Wooden side walls make some dissonance in the design, although they are made in the Marantz style, they do not look out of place, especially when the case is executed in black, as in our test sample. In general, the appearance and build quality of Marantz do not cause any complaints, the device looks strong and compact, despite the fact that there is enough space for connectors on the rear panel, and the control knobs are perfectly balanced. Also, remote control is included.


  • The look of the HD-DAC1, especially in the color of “champagne,” is very elegant and respectable
  • The developers from Marantz paid special attention to the reproduction of DSD


  • No line input on RCA jacks
