So you can confidently once may try existing RCA cable and if the sound transmission does not seem sufficient to buy this cable. The signal is transmitted clean and misfire-free. The contacts are pleasant massively, so do not bend as easily, if one may often other plug and stakes out. The cable is quite massive. (For a detailed analysis of the veins, I had to cut the cable, of course, what will but I do not do;.) Unfortunately, it is not very flexible, so it can be laid well not always. This leads to a slight point deduction.
Conclusion: It served its purpose (digital audio transmission / SPDIF) very good and at a fair price.
