Incredibly, what comes out of this part of a sound. In particular, the variable frequency output has it all. By contrast, my old stereo hifi system from Pioneer components and Arcus-standing speakers looks simply old, although this still brings the finer highs and mids. But the sum of the sound power this sound machine is just great and united Zimmmeranlage, mobile Partybox and ghetto blaster in one. Top recommendation for a universal music device with Bluetooth fantastic control.
