As in all good wireless audio systems, Philips has come up with a couple of boxes to link in the sound systems already dotted about your abode. The Philips Fidelio Wireless Hi-Fi Link is an unamped box which essentially Wi-Fi enables your stereo. That means you can fling all sorts of beats to it from your phone, tablet, NAS box or whatever you have. The powered version of that is the Hi-Fi Receiver which has 2 x 80W behind it and therefore can connect direct to any old set of speakers have without the need for a separate amplifier. All very nice.
