How to just use a Topping D10 as a usb-optical converter and not as a dac?


Standard Member

I borrowed a Topping D10 from a friend to see if my Hegel H80's optical input sounds better then the USB input. In multible reviews of the Hegel it is said that the spdif connections sound better so I'm curious to test this. The Topping d10 can, according to the internet, function as just a converter.

But how do I do this? The topping is connected to my nuc via USB. The Hegel is also connected via USB. In Qobuz I can choose between the two dacs. But if I select the Hegel dac, there is no sound coming from from the optical connection. There is probably a very simple solution but I cant find it anywhere online or in the manual. Its probably very simple and thats why i cant find it anywhere.

Anyone out there who knows how i can make this happen? Thanks in advance!

Your description is confusing - You mention the Hegel optical input but you talk about Hegel optical output not working and it is connected by USB????
