Now this looks like a bit of a bargain, on paper at least. The Crystal Acoustics BluDAC combines a Bluetooth receiver and digital-to-analogue converter in a compact box for £60 – undercutting Arcam's rBlink by £100.
Plug it into your existing hi-fi and you can stream music from your smartphone or tablet via aptX Bluetooth to your main audio system. Connection is made using either stereo analogue or optical digital cables.
