Are you considering investing in the Gustard X18 Pro DAC? If so, you have come to the right place. In this Gustard X18 review, we will look into the features of the Gustard X18 and answer the question: is the Gustard X18 worth the investment? The Gustard X18 Pro DAC is a digital-to-analog converter with excellent sound quality, a wide range of connectivity options, and a variety of features that make it an attractive choice for audiophiles and music enthusiasts alike.


The Gustard X18 Pro DAC is a highly anticipated piece of audio equipment. Unboxing the unit is an experience in itself. With its clean design and sturdy construction, it’s clear why many people are eager to review it. Inside the box, you will find the DAC unit, power cable, USB cable, and the manual. All of these pieces together make up the complete package that is the Gustard X18 Pro DAC. Once everything is unboxed, you can easily start your gustard x18 review and experience the top-notch sound quality of this pro dac.


Since the X18 DAC design has nearly identical dimensions to the X16 at 22 x 5 x 17cm and 2.5Kg in weight, it is fair to say that it is more of the same. That means a CNC’ed aluminum box that is pleasingly small, stackable, and won’t ever take up a lot of room on your desktop or HiFi rack.

Existing Gustard H16 amp owners should appreciate the dimensions because they should stack neatly on top of one another. In addition, I’ve been finding it to be a really cool DAC alternative to the more expensive Ferrum Audio OOR/HYPSOS amp and PSU combo, though since the company’s ERCO DAC was recently released, it’s once again out there on its own, feeding some other amplifiers.

The design is very clean, low-profile, and minimalistic with rounded corners and is available in two finishes: silver and black. Although I personally find black to be much more attractive, beauty is subjective.

The familiar partition-like lines to the right that divide an almost flush but grippy multifunction dial remain because Gustard did not significantly alter the original X16 design. Together, they form a multifunction control system for preamp volume control and menu operation. The function button for menu operation is located in the center of the dial.

Similar positioning can be found for the various inputs and outputs, which are all located on the rear panel, as well as the small, slightly off-center black and white OLED display panel on the front panel.

In terms of style, the X18 DAC OLED display employs a larger font and an off-white tone, which enhances legibility over the X16 screen’s tiny font and lessens potential eye strain.

The addition of a front panel power button on the X18 is new though the main power circuit is still activated by a fused 1/0 flick switch to the rear much like the X16. Gone is the X16 multi-circle machining on the far left front panel of the X18 which I honestly kind of liked as it added a bit of character to the minimalist styling.

When using LDAC from a Samsung Z Flip 3 smartphone in the same location, the range and stability within that range from the transmitting source to the X18 DAC are good but not quite as strong as the X16.

On the X16, I can easily travel up to 10 meters with just one wall in the way, but when I reach 10 meters from the X18 DAC, the signal starts to stutter and drop out a little.

My initial assumption was that the new stubby antennae, which are shorter and possibly weaker than the longer X16 version, were to blame, but after switching the antennae around, the outcome remained the same.

This could be a modification to the internal layout that weakens the transmission or a lower transmission power setting that lowers the risk of EMI.


Setting up the Gustard X18 is a simple process that won’t take long. First, plug in the power adapter and make sure it’s properly connected. Then, use your preferred audio connection to connect the X18 to your system. Finally, adjust the settings for the desired sound.
