Things to Consider

As mentioned above, different kinds of DACs available on the market. Moreover, these devices vary in terms of performance and price. Therefore, you need to buy the best option based on your needs, preferences, and budget. And this guide will help you in making the right decision.

What is a DAC?

DAC stands for Digital to Analog Converter Trusted Source Digital-to-analog converter - Wikipedia DACs are commonly used in music players to convert digital data streams into analog audio signals. They are also used in televisions and mobile phones to convert digital video data into analog video signals. en.wikipedia.org , and its only purpose is to convert binary signals in 1s and 0s into analog signals. Listening equipment like headphones, etc., doesn’t understand binary or digital signals.

These signals have to be converted into analog, so your listening devices can interpret them. And this is where a DAC comes into play. Now there are different types of DACs available on the market, and the quality of the output.

These DACs vary in terms of prices, features, and form factors. However, the best quality DACs can significantly improve your overall listening experience.

Features to Consider Before Buying a DAC

Different types of DAC devices are meant for different purposes. Therefore, you can choose budget DAC devices or premium quality options based on your needs.

Some people use DACs for their home studio or just for recreational purposes, while professionals use them for listening and knowing how all their notes are working in the final piece for recording or live performances.

Here are some important features that you must consider before buying a DAC that is just the right option for your purpose.

DAC Types

There are three different types of DACs; these are standalone DACs, headphone amplifiers, and portable DACs.

Standalone DACs

They are small USB boxes that come with a simple pair of analog outs. The USB connection here streams data and the voltage for the DAC circuit to work.

Headphone DACs

They are analog outputs for your speakers and can serve as separate outputs for your headphones. They also come with volume control for the preamp that you can control with a software program.

Portable DACs

These are portable in size, and they connect with tablets and smartphones. They feature mini-USB type-C ports like S.M.S.L M400, including a headphone DAC amp.

Inputs/Outputs

A DAC comes with several binary or digital inputs and a single output. Generally, the number of binary inputs on a DAC is a power of 2.

For most desktop or laptop computers, you will have to connect a USB cable to any available port on a device. After that, you will have to connect that cable to your corresponding input on your DAC.

If you want to connect your headphones, you should go for USB DACs headphones with an inbuilt amp. You can connect your DAC to any device using the RAC output.

These devices come with USB cables that you can connect to your computer. You can also use coaxial and optical digital cables to connect them to your music player.

And if you are looking to connect it to your stereo, you will need a stereo mini, RCA, or XLR cables like in the case of Audioengine D1 or S.M.S.L. M400. But mostly, they are equipped with USB connectivity.

There are balanced and unbalanced connections, respectively, referred to as pro and semi-pro. They can have dramatic effects on the overall audio performance.

The effect happens once the sound has been converted, but the balanced outputs have impedance balancing of the connected cable. Therefore, it results in the improved transference of the overall audio signal.

Most DACs come with RCA outs (unbalanced analog), mini jack out (analog), ¼-inch jack (un/balanced analog), XLR out (analog), S/PDIF (digital), optical 3.5mm & TOSLINK (digital), XLR AES/EBU (digital), wordclock (coaxial), USB, (A, B, C, mini), thunderbolt (rare), Firewire.

Bit Depth vs. Sample Rate

As you pursue the best DACs to buy, you will encounter two sets of numbers when going through the specs. These are bit depth and sample rates often given in kilohertz or kHz. These numbers are the numerical measures of how much data a particular DAC can transmit.

Sample rate refers to the number of times recording something per second from incoming audio. A piece of recording equipment or program doesn’t record in a continuous stream and can only sample the signal that it receives.

The more times the device can do this, the better the quality. Furthermore, these samples have some info which is called bit depth. And the higher the bit depth in each remission means there will be more data per transmission, and the overall quality will be better, as in the case of RME ADI-2, Gustard DAC-X16, and S.M.S.L. M400.

Each song you record has its sample rate and bit depth, while the numbers given for a DAC, you are looking to buy the highest bit depth and sample rate that it can manage. And, of course, you want both these numbers to be as honest as possible for the DAC you are looking to buy.

MQA

MQA refers to Master Quality Authenticated, and it’s a file type unique to the Tidal streaming service. With this file type, you can conveniently stream a hi-res file on the internet, and you won’t have to compromise on quality. FiiO BTR5-2021 supports this file format.

The source file is pretty large, and it is folded by various programs to pack it into a small file for transmission over wifi. The concept here is that this MQA file (on Tidal) sounds better than other hi-res files (on Spotify, etc.).

However, there is an issue here, as YouTuber GoldenSound pointed out in this video. The conclusion from this video that we can draw is that MQA is not a lossless format, but it also adds to the noise and other artifacts.

Now, MQA is a separate entity as it is the company that licenses the MQA file format to Tidal. In response to the video, they contended that the MQA file format could only deal with natural sounds and not the sounds uploaded in the video by GoldenSound.

This response is useless as Tidal’s software program works pretty opaque. On the other hand, DSD and PCM are both open-source programs, and they both have been thoroughly tested. Any new file format should be subject to thorough testing if it needs to sell as better than the rest for millions of users. And its claims should be backed up with facts.

So, objectively speaking, MQA doesn’t stand its ground in top performance. The tidal service is excellent, but it should only work if you want to buy a DAC to work on MQA. Otherwise, you need to look elsewhere.

DSD

Ever since the hard evidence about MQA and its performance came out, DSD became the criteria to measure any DAC’s quality. It is an audiophile DAC and proves to be a yardstick for those who have hi-res libraries.

It refers to Direct Stream Digital, and it is an audio protocol called 1-bit SCD bitstream, a file for Super Audio CDs. This file format comes in several resolutions, and the highest resolution is DSD256 or Quad-DSD, which can snake audio at 11.2 MHz. It is four times the sample rate of SACD.

You will need a specialized player that can process DSD format, and your iTunes player will not get the job done here. For this, you can go for Audirvana Plus. Once you get it working, prepare yourself for a wide ride

R-2R vs. Sigma-Delta

Now, there are two different types of DAC conversion technologies; these are Sigma Delta and R-2R. R-2R uses a chair of resistors. Some of them have a value of R, and some have a value of 2R.

R refers to the number of resistors and the particular value. If you arrange them in a particular way, some resistors double their specific value. One such arrangement is the ladder arrangement, with 2R resistors working as rungs and Rs using side rails.

These resistors work together to translate voltages and create analog sounds from digital signals precisely. This specific method is extremely accurate and reduces any noise or digital artifacts to a minimum.

Still, there are not many DAC devices that use this. The R-2R circuit is expensive despite being simple in design and construction.

A more affordable option is the Sigma-Delta. They are also referred to as delta-sigma, and this name comes from a mathematical process used for conversion.

This construction doesn’t come with a neat line of resistors and has various components that work together to get the job done. This type of construction spreads the noise around and makes it much less audible. From there, the signal is sent to the delta-sigma modulator.

The modulator alters the oversampled audio into a bitstream with a high sample rate. And it further reduces the noise. After that, the signal goes through a low pass filter and a digital decimator for further processing to reduce noise.

Our Verdict

As per our assessment and analysis, SMSL M400 and Gustard DAC-X16 are among the top three DAC devices available today.

The M400 features 2 channels and RCA and XLR analog outputs with USB, optical, coaxial, Bluetooth, and IIS digital inputs. It comes with a sample rate of 768 kHz and 32-bit depth.

Gustard DAC-X16 has 2 channels and a similar sample rate and bit depth but comes with 2 CLR and a dual RCA analog output. It features 1 coaxial, one optical, I2S, and AES digital input, and it runs on USB-B.

But the best DAC on the market today is the RME ADI-2 which has a similar number of channels, sample rate, and bit depth. But it comes with more connectivity options as you can connect it with your headphones apart from the conventional analog outputs and digital inputs. And that is why it wins our Editor’s Choice Award.
