Clear the Bose ST20 is sonorous, but it also costs twice as much. The Denon I ordered for the nursery to sleep. But I have used him in the "furniture assembly time" really loud. The sound is really good, the display can be finely resolved sher read well and the volume gradation is very spread out. Does that mean that he can make very good quiet and loud. For other speakers me has already happened that the correct volume was exactly between two stages. In the nursery it is for falling asleep on 33. That should say it all. Artist and title are also displayed on the display. The volume he remembers that but I think an Airplay function. He turns instantly when it is needed, on or off is not necessary. The decor was very knowledgeable about the app. And yes, it can even radio stations are saved in the app, and then on the device without durchgezappt App mehrfaliges by pressing a button.
I think he's a very good alternative to my two Bose ST20 and in my opinion it is a beautiful and functional Airplay speaker with an excellent price / performance ratio.
