Model:SH-AU02A

I originally gave it one star but in further developments it proved be an issue with my DAC's. When it went down again I plugged it into my headphone amp that has a coax input. and It sounded perfect. As for anyone saying the sound was sub-par, they are fooling themselves. This hobby os full of the self confirmation bias types. This is an excellent unit. My bad for the earlier post and my apologies to anyone who say it.

I got this to convert USB audio out from my new micro PC into optical in for my stereo receiver (again stereo- not surround sound). This works great, sounds better than analog. I used a 10ft USB 2.0 B to C cable into the DSD and my optical cable from DSD to my stereo receiver. Powered by USB, it's easy to conceal. The ONLY issue which some have mentioned is volume control but it's much less of a problem than what some have posted: all the apps vol controls still work fine (WM, VLC, Youtube) and there is no problem with audio synching to the video. The only issue is that my keyboard's vol+/- keys no longer work (mute still does though). So it's a small price to get good stereo audio again. Update: I found a great app Volumey that restored my Kensington keyboard's volume+/- keys so all good! In the app, go to Misc, then Synchronize volume of all apps to Master. That's all you have to do. Whether you are streaming, or using VLC, even minimized, it works perfectly.

I am using a KVM switch for a mac and a pc computer. Both of them recognize the DSD (which is plugged into the KVM switch). the DSD TECH SH-AU02A is connected to a LG sound bar using the optical cable.

Using this to convert USB audio from my PC to a TOSLINK cable running into a DAC. It works perfectly. The resulting sound is transparent, no noise, clicks or pops. I like that status light and the 3.5mm output for headphones. Very compact, very solid, and good looking -and a very strong value at the price listed. Highly recommended!

Context, I am a bit of an audiophile so consider that when processing my thoughts. I wanted to use this with my phone into an external dac. It is functional. however, output is low. Have to turn phone up almost all the way and that seems to distort the sound enough to be noticeable. Sound quality is just really not good. Flat and grainy, lacking clarity too. I can't listen to is. May be fine for you, just not if you expect something akin to decent quality sound.

It drops the connection to my computer whenever I touch anything in the room where there is a static discharge.

I bought this to link my Sony NW-A307 Walkman USB out to my car's audio system which, via an AudioControl DM-608, can accept a TOSLINK or COAX input audio source. I previously tried two other devices: 1) Cubilux USB C to SPDIF Adapter, which worked sort of (dropped connection on track change) 2) Douk Audio U2 XMOS XU208: complete fail, despite claims it would work with Android, did not even recognize the Walkman (NW-A307 runs Android 12) I am happy to say DSD TECH SH-AU02A works perfect! Audio routes from the Walkman over TOSLINK to the DM-608! The link between the devices remains when skipping tracks or when the Walkman is on PAUSE or STOPPED. Audio quality is great! Wish I had tried this device first!

I am using this to play MP3s on my laptop over a 30’ optical cable to a Schiit D/A converter at my stereo. It works exactly as intended with high quality sound. One difference I noticed from my previous setup was what happens when there is an bitstream interruption from the laptop. My previous setup would hard dropout (like an LP scratch), whereas this converter temporarily reduces the volume and then returns to normal. Obviously there should never be such long bitstream interruptions, but the gentle volume reduction in these situations is much more desirable than a hard dropout. Recommend.

Recommend alot! Very easy to use, allowed me to use my woojer 3 and Headphone at the same time without sharing bandwidth ☺️☺️

Funktioniert ohne Treiberinstallation unter Windows 11 und MacOS. Ich verwende den Adapter, weil ich über den Klinken Lineout eine lästige Brummschleife hatte. Unter Windows gab es das Problem, dass nach einem Neustart das USB Kabel ab- und angesteckt werden musste, damit der Adapter wieder Ton liefert. Wenn man den USB Device Suspend deaktiviert klappt es dann aber ohne umgestecke.

Excellent device for motherboards lacking fiber output, it removed all my coil-whine and grounding hiss while keeping decent audio quality. I'm considering going full optic audio now, can't wait too see the evolution of DSD devices. I really hope they get more in stock because I need to order more.

Perfecto para mis Senssheiser RS175 con mi placa base nueva, no me di cuenta que no traía salida óptica, facilísimo de puentear y poner el sonido en vez de digital en auriculares , pero el sonido totalmente limpio y digital.

Très bien. En sortie de l'ordinateur avec un câble USB et en entrée dans un convertisseur audio avec un câble numérique spdif. Excellent rendu sonore
