There are plenty of gadgets that will stream music across the home, but few of them would satisfy the stereotypical audiophile. Cambridge Audio's just-shipped Minx Xi system may appease those fussier listeners. The WiFi sound hub includes its own 24-bit / 96KHz Wolfson DAC, a Class AB amplifier and even a toroidal power supply to minimize interference at higher volumes. It can also decode compression-free formats like AIFF, Apple Lossless and FLAC. There's no want for input sources, either. The Minx Xi takes local music from both Cambridge's mobile apps as well as devices with Bluetooth, optical output, UPnP and USB support; by itself, the hub streams services like BBC iPlayer, Pandora and Rhapsody. The Minx Xi isn't cheap at $899, but it's also one of the few networked audio devices that could be a true complement to high-end speakers.
