Viprof Electronics has developed the VE0126 Up2Stream interface that enables conventional power amplifiers without digital or streaming inputs to play Spotify and other network audio. The device connects streaming audio to the amplifier’s auxiliary input, allowing users to modernise existing audio systems without replacing the amplifier itself.
