KEF Connect & KEF Stream
There are two apps — ‘KEF Control’ gets you connected and also acts as a remote control, useful if you find the supplied physical remote with its red-on-black markings as difficult to read in anything other than bright daylight as did we. If you select the Wi-Fi input, you are shifted to the ‘KEF Stream’ app, which offers the highest quality path for music to the KEFs. The menu of KEF Stream (inset on the screen above) distractingly offers ‘News’, which turns out to be KEF news, and news about the LS50s at that... Rather more useful is ‘Playlists’ and ‘Library’, which show music stored on your device (other manufacturers say Apple is now preventing this, which would seriously hamper playback for iOS users of the LSX if they did). Below those are Tidal, Spotify (the KEFs use Spotify Direct under the control of your Spotify app), and ‘Media Servers’ for UPnP network streaming — we played high-res FLAC, WAV, AIFF and AL this way, though a 24/192 WAV file proved too much for something in the chain.
