Inconspicuous small miracle part

Hello,
I have an Internet Tuner by X4 pond the 1200s. Unfortunately, this only has an optical output, the successor had both. But why buy a new device the same if it is not broke? Money you get eh not much for this device, so I wanted to keep it. But what bothers me is the very sound which is underwhelming and you quickly realize the differences in quality of the individual channels can receive the X4. Since I have a Cambridge DAC with BNC connectors, as this fits together nothing. So talk looked at Amazon if it visually is absolutely a Converter / Adapter for Digital Coax.
After much back and forth I decided to deleyCon because it goes in both directions, but not many others.
So connected power, the cable plugged in and happening only once nothing Oops, I have the input and output confused, so reconnected the cable and lo and behold, even I could hear music and in a very different sound quality, what such a DAC and a converter can change everything ....
Therefore, what it for me. A great success and not regret buying

With Best Regards
