The Fiio Taishan D03K outputs a clear signal. Unfortunately, the level of my LCD TV Toslink (Samsung UE40H5070) is simply too low. In my system I have to turn up Yamaha too far the volume control always.
The solution is the level translator kit from ELV. This amplifies the analog output of Fiio again later. The solution is simple top.
I had already tested several D / A converter at affordable prices. All were silent. Now all is well
