Unfortunately, I do not understand the technical stuff, the results in this case partly negative reviews. I've just bought the connector to listen to Internet radio and Spotify on my Rotel system. And that works just fine. I wanted to use no network audio player for hundreds of euros just to another source of music. Package received, out pact, read brief description, connected and off we went. For the longest time, the search for the note to the WLAN key lasted. Length of time between adoption of the Postal floor and hear the first song twenty-five minutes. Since then, the thing runs and runs. So far, no problems have been encountered, the wireless connection is stable, the operation is so simple, so that they also understand someone without studying computer science. And then the price that deserves at least two more extra points alone. How the thing works (SMB, CIFS, NAS, QA, DAC, UPnP, DAC ...... etc) I do not want to know, I do not understand anyway. To many contemporaries, the logs here to speak, but this seems to be more important than the music. But that's the point really in this device, or. I do not know to this day how the TV picture comes to my house, so what.
