What is it?

Our products are network music players where new electronics have been retrofitted into 20th century design items. The player connects to your home network via network cable or wireless Wi-Fi and is also connected to your existing speakers. It plays or rather streams digital audio files from the Internet or locally stored music on USB flash memory sticks, from folders on your PC, Mac, tablet or music stored on your smart phone, or any network-attached storage (NAS). You can also listen to live web radio stations. The music player is, depending on the digital source format, capable of delivering Hi-Fi stereo sound of audiophile quality.

What are you able to do?

You can stream digitally stored music files of almost any format; the most common formats are:

MP3, the most usual music file format for digital audio.
WAV, Waveform Audio File Format - the Microsoft and IBM music file format standard originally for storing audio bit streams on PCs, but now used on many devices.
FLAC, Free Lossless Audio Codec is an open source music file format for lossless data compression, which gives uncompromising sound quality .
ALAC, Apple Lossless Audio Codec is a music coding format developed by Apple Inc. for lossless data compression, which also gives uncompromising sound quality.
MPC or Musepack, is an open source music file format similar to MP3.
AAC, Advanced Audio Coding is a new music file format that is designed to eventually be the successor of the MP3 format.
DSD, Sony and Philips' Direct Stream Digital format. This is a high-resolution format that produces the signal by sampling it in a different way than the formats above.

    With your Spotify premium account you can through Spotify Connect use the ordinary Spotify app to stream music.

    Airplay can be used for streaming from iPhones and iPads (or any device supporting Airplay) to the player.
