best usb dacs under the $100 guidelines: what to look for when shopping for a usb dac?

USB DACs under $100

physical design

Digital-to-analog audio converters (DACs) come in all shapes and sizes. they can generally be classified into a few categories.

an online dac

this is basically an upgraded cable. At one end is a USB connector for connecting to a phone or similar device. at the other end is a jack for plugging in headphones or earphones. Inside the molded usb plug are one or more integrated circuit (ic) “chips” that do the conversion and amplify the output.

These types of dacs are very small and lightweight, and ideal for use with a phone.

high-end dacs

They often resemble a typical memory card, also with a usb connector (usually a full size usb type) and a headphone jack on opposite ends. because there is more space inside the case, they typically have more complex circuitry to provide better audio conversion and filtering, and more power.

they work well with a desktop pc or any device that doesn’t move around too much and has a usb port.

a variation of the memory card design has a usb connector (female) instead of a plug (male). This allows you to connect your own USB cable of any length. larger models may include a volume control, control switches, and additional outputs.

desktop dacs

Finally, we have desktop dacs that usually come in a traditional rectangular case, with front panel controls, including a large volume knob. On the back are all the connections, which can include USB, optical and coaxial inputs, and stereo line outputs. are typically powered by AC “wall wart” adapters, making them impractical for portable devices.

connectors

first, to get the terminology correct: protrudes a “plug” or male connector; a “jack” (female connector) is recessed.

usb connectors come in several flavors. The wide, flat plug on the end of a memory card is a USB A connector. a smaller, squarer connector is a type b. Mobile devices typically use a micro-A connector, which is smaller and more durable.

what about the audio connectors?

all dacs reviewed are equipped with 3.5mm stereo audio jacks. most wired headsets and portable headsets have plugs that are compatible. studio headphones often have larger 1/4-inch plugs. to use them, you will need an adapter.

power output and impedance

all dacs reviewed include a small amp powerful enough to drive a pair of headphones. some also include a line level output for powered speakers.

The amount of power varies, with the simplest models providing around 130 milliwatts (mw). this is enough for a typical set of headphones, though probably not enough for high-impedance headphones.

what is impedance?

Impedance is the resistance to an AC electrical current, measured in ohms. headphone impedance can vary, from 8 ohms to more than 600 ohms. higher impedance headphones generally sound better but require more power for the same sound level. headphones are typically between 16 and 32 ohms.

In other words, connecting your high-impedance headphones to a 130mw amp won’t give you much sound.

sample rates and bit depth

There are two variables in digital audio that are most important in determining the quality of the audio. The sample rate indicates how many times per second the original signal is measured and stored as a number. a sample rate of 44.1 kHz means that 44,100 samples are taken per second. bit depth indicates the precision of a sample.

“cd quality” and more…

Compact discs (CDs) contain digital audio sampled at 44.1 kHz and 16 bits. that seemed unbelievable 40 years ago, but today it’s considered the bare minimum for high-quality music playback. other popular sample rates are 48, 96, or 192 kHz. the higher the sample rate, the more accurately high frequencies are reproduced.

A 16-bit sampler can have any of 65,536 (216) possible amplitude values, while the 24-bit sampler provides nearly 16.8 million values, making it much more detailed. the nearly infinitesimal resolution of 32-bit audio (4.3 billion values) is useful primarily in audio mastering applications.

digital audio formats

Digital audio can be stored and transmitted in various formats. but not all dac can decode all formats.

pulse code modulation (pcm)

This is the standard form of digital audio for computers, CDs, and other digital audio applications. With pcm, the amplitude of an analog signal is sampled at a regular interval (the sample rate), and each sample is rounded (quantized) to the nearest available value.

direct broadcast digital (dsd)

this is a system originally used by sony and philips for their super audio cd’s (sacd). It is capable of reproducing sound significantly superior to CDs. there are several variations of dsd, based on the sample rate. dsd128, also known as double-rate dsd, and dsd256 (quad-rate dsd), are popular formats.

dsd512, or octuple rate dsd, is also used primarily by digital audio workstation (daw) software.

master quality authenticated (mqa)

this is a new technology that can enhance the audio of a traditional cd or audio file. you can also make special mqa cds that take advantage of this innovation.

what is mqa?

The technology behind mqa is complex, and a full description requires some time. suffice it to say that it “erases” the audio by clearing the timing of the samples. when combined with an mqa decoder, an mqa file can sound identical to the original master recording.

Now that’s all covered, let’s take a look at a selection of the best usb dacs under $100 currently available…
