audiolab M-DAC Nano
This small, lightweight wireless streamer accepts Bluetooth aptX signals from portable devices - so no cable is required between the source and the nano.
The microphone enables calls and voice control (e.g. Siri) to happen within earshot of the nano, not necessarily the phone.
Charging the unit is done wirelessly, too. Placing it on the Qi charging pad for two hours provides eight hours of playback.
The numbers are impressive and illustrate the M-DAC nano's high-res credentials. It can upsample signals to 32-bit/384kHz prior to converting them to analogue and sending them to the nano's built-in headphone amp.
