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.
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.
