An absolute tool of necessity in certain situations - rendered excellent audio results on my end!

Every once in a while one comes across USB audio problems between various components such as DAC's and your PC, that for the life of you, cannot be remedied. These problems can range the gamut from things like a DAC not being recognized by your PC, or USB line noise that that you just cannot get rid of. I know, I've been there! As a user/audiophile and audio reviewer (mostly with desktop, near-field scenarios), I've encountered many issues regarding USB connections, and they either weren't easy to remedy, or were just not fixable.In many of those instances, you begin to wonder about "other connections, other than USB." In my case, my PC didn't have an optical output connection, so I didn't have many options available.After scouring various websites for information, I ran into this unique Douk USB to Toslink/Digital Coax converter on Amazon, and I figured, why not give that a try. The issue I was having is that one of my DAC's had a high-pitched constant RF type of noise (that none of my other equipment experienced) that just wouldn't go away and definitely interfered with my music listening experiences. And since my PC didn't have any type of optical outputs, I was left with having to connect via USB.After trying countless supposed remedies (that have worked in the past), I almost gave up. However, when I connected the Douk converter, connecting the USB end to my desktop PC, and then running a optical Toslink cable (or Digital Coax cable) to my FX-Audio DAC X6 Mk II, the issues disappeared completely - pure silence! But more so, there were no losses in audio quality. In fact, to my ears, I found the music a bit more dynamic.Now do keep in mind that if you are using a DAC (in my case here), when connecting the Douk USB to Toslink converter to your PC's USB connection, the PC will show the device not as a DAC, but rather, it will show up as the Douk unit and the max it can go up to is 24 Bit 192 kHz. So keep that in mind - and nothing is lost audio quality-wise (at least from what I could determine). The results were far better than I could have even imagined (along with the pure silence). Also, keep in mind that this Douk unit also has a digital coax output. In fact, you can have both a Toslink and Digital Coax cable attached - with both outputs streaming music simultaneously (I love that).If ever there was a device that could fix certain unique USB issues, this Douk converter is the fix. Now granted, it is essential that the device you wish to connect to the Douk must have an optical Toslink input (or a Digital Coax input), otherwise, you'd be wasting your money here. Some DAC units only have USB inputs, and you're left with few options on those. But most have at least a Toslink connection also - and some also have Digital Coax inputs on top of everything else.All in all, for what it does, the subsequent fixes it employs, and more so - you lose nothing audio-wise - I cannot help but assign it 5 full stars with no reservations. Plus the price is very, very reasonable.As with any review, these are based on my experiences. Your mileage may vary...Highly recommended...

Super - a true audiophile quality component.

The sound quality of this box is really excellent. I'm using it to feed 24/192 PCM audio from a Windows tablet computer to a Benchmark DAC1, using a glass optical cable. That particular DAC is very sensitive to the quality of its input. I was using a SMAKN CM6631 audio interface, but I thought too much of the activity in the computer could be heard through it - particularly the beginning of each song was brighter and more forward than the rest because the player is using the computer a lot during that time. So I decided to try this box, and that problem is gone. The sound is uniformly good now.I thought the imaging was a little smaller though, so I tried some of the changes that had made the Smakn box sound better - a shorter USB cable, and external power supply. I originally set up the Douk box using the USB OTG cable that came with the computer, and the longish USB cable that comes with the Douk. The OTG cable has an input for external power to avoid draining the tablet battery to run USB devices. Using that improved the sound, but only a little. Disconnecting the computer power (with the OTG cable, both power supplies are really connected) and using a short cable finished the job.Unfortunately the Douk designers didn't allow for external power for their box. The Smakn box has a separate power input jack and a switch to choose external power or USB power, which made it really easy. For this box, I had to wire my own USB plug. What I made is a USB "cable" that's about an inch and a half long, with a micro USB male plug on each end, and a power wire coming out the side. The computer side is wired for OTG (pin 4 connected to pin 5), and no power (pin 1 not connected). The Douk box side has the power (pin 1 +) and ground (pin 5 minus) connected to the external power wire. The rest are connected normally.Using this "cable" and an external linear power supply makes the sound really great for me. The images are normal size now, and depth and clarity are as good as I've ever heard. I do wish the designers had made this easier by putting a power jack in the device, though.If you try this, I really recommend using a linear supply. Most power supplies these days are the switching type, and make a lot of electrical noise. Linear supplies use a transformer instead, and make less noise. I'm using a C-TON PW2-5 (5V 300ma linear, $16 at Digi-Key). It sounds VERY good. If your DAC has better jitter immunity than mine this may not make any difference, but it doesn't cost much to try it.Even if you don't try the external power, it will probably be worthwhile to place this device right at the computer's USB jack and use a standard adapter (with whatever connectors you need) to replace the cable. USB cables cause jitter on the signal, and pick up electrical noise too, so less is better, and none (just a short adapter) is the best.

Driver issues with Windows 11

The hardware is good - the vendor seems like using new interfaces like USB-C - but completely ignores the driver-side of things. The device functions with Windows 11 - but generates "unknown device" errors. Driver downloads that are out there are unsigned, experimental - or require third-party account registration to download - and honestly - my security-engineering side tells me this smells like a way to get malicious software into people's machines.If you buy this - and it works without drivers - leave it that way - you're more secure. Otherwise return it and demand the vendor completes the product. It would be worthy of 5-stars if drivers were done right - working SIGNED windows drivers are needed. In it's current for I do not recommend.

So far, perfect soluion

Have this running for two months now. Perfect solution for my use: wanted to stream hi res from my Windows 11 Asus laptop to processor/amp. No special setup required on Windows 11. I have my laptop connected to tb-4/usb-4 docking station, then usb from docking station to this device, then digital optical out from device to processor/amp. No issues for set up, and supports up to 24/192 audio streaming from my streaming service. Quality is great, no difference from when I directly connected digital optical from my old desktop to processor/amp. Note, I did not test DSD and that does require a separate driver according to instructions. This device seems to cost more than many others, but for the trouble free install and operation, I am very satisfied. And Windows volume control does work.
