With the WiiM Vibelink Amp Gray, you can get everything out of your passive speakers. The amplifier has a high power, so it emits detailed and bright sound. Thanks to the Post Filter Feedback technology, the distortion in sound reduces and you hear a bright sound. Even when you use different types of speakers with different resistances, the amplifier works well together with the WiiM streamers. That way, you can stream music from Spotify to the streamer and you hear your favorite music through your speaker via the amplifier. That way, you can choose from different music sources. In addition, you can also connect other sources to the amplifier via the RCA, optical, and coaxial connector. For example, a record player.
