4. Cambridge Audio StreamMagic 6

A network music player that has an integrated up-sampler to squeeze every last inch of musical code from files played from a uPnP computer, NAS drive or internet radio station. It'll also buff the audio from external devices connected to its twin – or USB 24-bit digital – inputs; Blu-ray players, iPods. iPhones, that kind of thing. Add the aptX-compatible BT100 Audio receiver (£70) and you can stream high-quality tuneage over Bluetooth. Impressive.
