KGUSS FX-Audio DAC-X6 Mini HiFi 2.0 Digital Audio Decoder DAC Input USB/Coaxial/Optical Output RCA/Headphone Amp 24Bit/96KHz DC12V(Silver)

This thing is excellent, robust, great sound quality and being able to leave the headphones plugged in all the time and still have it go to the speakers is a really nice touch. I just turn the speakers off when they aren't wanted. I love the look too, it matches my silver 70s amp stack nicely

I purchased this DAC for it's coax digital support with the intention of assembling a TV sound bar equivalent. I have a couple of audio interfaces that are USB only which could not be used for a disk player. The sources are a desktop computer running Ubuntu 22.04 and a Sony 4K blu ray player. The FX-Audio provides inputs for both. The volume control on the front does not apply to the RCA out connectors on the back and that is clearly stated in the product discription. The unit sounds great for both streaming from the computer or watching disks on the Sony player. The unit's case is of brushed aluminium and the face plate is brushed aluminium about 1/2 cm thick. It has a solid quality feel when you pick it up. This is a first rate choice from the budget DAC category.

It uses an old Cyrus logic DAC and apparently doesn't return Stella test results. However listening to it driving a 1986 Nas 3020 and some modern Tannoys it sounds superb, it's fast amazing mids and driving bass. It's on the warm side but fast and clear. It's actually got decent simple switches to select input options. Compared to the remote control dacs this is a breath of fresh air simplicity. It includes a UK plug power brick and decent usb a cable to usb b

This DAC/Amp is a lifesaver. I travel for work sometimes, and since I've gotten some nicer headphones, (Hifiman HE-400i), I realized that my computer could not properly drive them enough to get any appreciable sound, which doesn't work for me if I'm watching movies or playing games in my hotel room. Also, I do not like using the hotel TV's built in speakers, as they usually sound terrible and the noise might disturb other guests. Most hotel TVs might have a speaker output jack, or an A/V box mounted to the rear of the set, but they typically don't allow volume control since they're geared towards an external amplifier to control the volume. This means headphones will get the full power output at all times, since the TV sound option for external speakers typically disables the volume control. There are some tvs that might have an actual headphone jack which means you can still control the volume, but even so, the output might not be sufficient, depending on the type of headphones you have. This DAC/amp is very well made--surprisingly so, considering the price. The body appears to be brushed aluminum, with a front plate that is nearly 1/4" thick. It has a nice bit of heft to it, and the 1/4" headphone jack is a definite plus. The toggle switches for power and input selection are sturdy with no jiggle whatsoever. Best of all is the volume knob. The knob is a big deal for me, and one reason I returned a different model before finding this one. It's large enough to be comfortable to turn, the unit is tall enough so that the knob isn't too close to the table, desk, or whatever surface the device is sitting on, and finally, it is detented. It's not a continuous smooth turning pot, but rather it has a light satisfying notched detent at each degree of adjustment. It's very satisfying, and for me, is an indication of a well made device. Opinions on this feature may vary, but it does it for me. This means the volume stays where you set it, so if you do pick up the DAC/amp to move it for whatever reason, your hand is unlikely to accidentally adjust the knob. The device also comes with a seemingly well made, sturdy USB cable and a power supply. I don't recall if it came with an optical cable, but I have my own. The only downside, which is a small one, is that the power adapter has a blue LED that is incredibly bright. I like the room to be dark as possible when I am sleeping, and this LED is so bright that it lights up the area of the room where it's plugged in, and is distracting. It's a simple fix--I would toss a sock over the adapter, or move my power strip behind a suitcase or curtain and then. I could sleep. A band-aid or small piece of electrical tape could also do the trick. That is my one and only complaint, but it's worth mentioning so you can be prepared to deal with it if it's a problem. The unit also has power and input signal indicator LEDs which are on the front, but they are very small. They're easily visible, but not overly bright as to cause a distraction during use. These lights turn off when the unit isn't being used, and there is no annoying standby power LED on the device to stay illuminated when it's turned off. The sound is excellent. There is absolutely no noise (another issue I had with another model from a different brand that I returned), and the volume is more than enough to drive my planar magnetic headphones. It doesn't color the sound, there is no lifting of veils, widening of sound stages, or any other nonsense, it just works. It accepts the digital input, whether it's optical, digital coax, or USB, and can make it as loud as you could reasonably want it to be, cleanly. If you've been considering a DAC or headphone amp, or may have to travel and stay in a hotel, you might want to consider getting this if you plan to take corded headphones, even if they're not difficult to drive. You still might find yourself needing some volume control, and simply plugging headphones into the hotel/AirBNB tv, if it eveb has a headphone jack, might not work. In the included pics, it's setup at home, although my surround sound receivers can drive my headphone just as well. I just like using it because it's a great device, and again, the volume knob is so satisfying with its subtle but well-defined detent. I have not used the preamp output section, so I cannot comment on its performance.

I got this DAC as a way to get rid of various noise that is very common in analog audio coming out of a desktop computer. This DAC, though moderately priced, is very well built and works perfectly with optical interface. Coupled together with Edifier R1280Ts speakers, this works like a charm. One thing that I would have wanted to see is a way to cut off RCA output to the speakers - either as a switch or tied into the headphone jack. But if your speakers have their own mute, then this is not a problem. The USB interface seems to work well too, although I'm not using it so I can't say for certain.
