Firestone Audio Libby (£499)

摘要

With an accessible, pleasing look about it, the Libby is actually one of the more complex products here. It's the built-in DAC that provides USB input but, like the Aqvox USB 2, it also has coaxial, TosLink and AES/EBU digital inputs. Unlike the Aqvox, it also has analogue line inputs, but signals from these are routed through a built-in analogue-to-digital converter, to be converted back to analogue by the DAC. Another pair of phonos provides a fixed-level analogue line output for connection to a preamp, while the front panel headphone output has its own volume control.
