Review: Good piece of kit. - Product as described. Works as expected. Would buy again.
Review: All good - Works a treat. Wanted galvanic isolation from the laptop USB to the DAC. This very diminutive bit of kit that fulfilled my requirements; it is very small and very well built, came well packed in a plain no fuss cardboard box. I'm running Windows 10 and the desertcart HD app. Plugged in the convertor and Windows 10 saw it and set it up with out a hitch. For Windows 10 you shouldn't need to load up the XMOS driver as its baked in. I checked the XMOS web site and that's what they say; however you can get a driver from them if you did around. It's the same one that Nobsound reference to in their instruction manual i.e. they give a Google docs link and not a QR code - the Google Docs link works ok, where as the CD supplied had nothing on it? I did try the download but that messed things up and I had to remove the driver from the device manager in Windows. When Windows 10 has installed the Nobsound convertor do a right click on the sound icon in the tool bar and open the Volume Mixer setting. Click the speaker and select the advanced tab. From the drop down menu select the required sound setting and apply. I went for 192khz / 24 bit as that's all I need. I don't play music any greater than that sampling and bit rate. I then checked if the desertcart Music app was seeing it ok. When playing an album I clicked the HD or HD Ultra and it came back and said that the device was capable of 192/24 and what Khz / bit rate it the music track was playing at. Happy days :-) Sound quality is excellent to me via the Toslink. For the audiophiles out there: DAC is a Topping E30 into a Cryrus 8VS2 amp (+PSX PSU) and then hooked up to Q Acoustics 3020 speakers using Tellurium Q Black speaker cable. RCA's are Tellurium Q Black from DAC to amp. Toslink SKW cable. Enjoy.

### ⭐ Douk U2 converter
*by S***. on 16 May 2026*

Makes poping noises on optical , did not get it to work with my phone ,it just did not lock on with the coaxial line and kept poping and making very loud noises, maybe I got a bad unit , don't know what to think but just did not work anywhere close to what I expected.
