I have heard the Denon in direct comparison with the Bose SoundLink III. Volume Technically it can not keep up with the latter, of course, is in itself sounds of the Bose also certainly impressive "big". Comparing the Denon plays but simply adult, the bass can be found a better and in the heights it sounds yoy. the Bose as if you take a towel from the speaker.
Considering then the price - a sharp product! More sound will hardly be possible in the size, the processing is great, robust, operation without a question mark. 5 Stars.
