Before the RS520 i used a Cocktail X12 with which i was satisfied for many years. It had a few draw backs like hiding all music in cryptic directory structure, no high res FLAC files…
What i liked about the Cocktail X12 was the huge list of internet radio stations per country and a special feature for “local radio stations” and genre which worked pretty perfect.
By choosing “local” i got an extensive list of radio stations around my area (i think from geo locating my external IP). The same extensive list i got when choosing a country or genre. This was still working even after 8 years of purchase and after the end of life of the X12. Such things help to keep the value of the purchase.
The internet radio listening with Cocktail X12 was a higher quality comfort, much easier experience than with the ROSE520. I would wish to get that internet radio experience back and implemented in RS520.
