It's been working for over a year with no problems. I forgot it was in that particular signal path until I noticed it recently.

used to convert usb hi res to spdif high res from my Mac mini m2 to Rega dac. Works great.

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.

I bought a cheaper DSD tech adapter on Amazon before this, but that one doesn't change the volume. This one works perfectly with my Windows 10 volume control.One red flag is that it came with a USB stick that has drivers on it. I don't really want to install unsigned drivers onto my PC, but when I plugged in the device, it worked without using the USB at all. I guess they submitted their drivers to Microsoft and got them signed.I did notice that audio above 24 bit 96000hz cuts out intermittently, but I don't know if that's another part of my setup or this adapter. I don't really care either way.

Recently Installed the Douk Audio U2 XMOS XU208 usb to coax converter between my Mac mini M2 and Auralic DAC/Creek integrated amp powering psb speakers in my office. I like that for the Mac no drivers are required. Using JRiver Media Center 32, Cannonbball Adderely’s Somethin Else 24/192 flac files sound great. For this system I do not believe that spending ~$500 for one of the “audiophile” alternatives would be worth the added expense.
