British hifi maker Cyrus Audio takes to Kickstarter to fund development of the SoundKey-- a micro DAC designed for smartphone and tablet use.
According to the Cyrus, while the SoundKey is small and lightweight (around 16g) it still carries a high quality DAC and amplifier to improve mobile device sound. It connects via USB and sips just 50mA of power from the phone, half that of rival products.
It is compatible with Android, iOS and Windows devices, as well as laptops and PCs.
