Ayre QB-9 DSD

摘要

There are some definite oddities about the £2495 Ayre QB-9 DSD DAC: resolutely a one-trick pony it's an asynchronous USB converter and that's all. It has just a single USB Type B input plus RCA phono and XLR balanced analogue outputs, and a display to show the sample rate to which it's locked. There's no remote control, no Bluetooth or AirPlay, not a sniff of a coaxial or optical digital input, or even a power switch... connect USB, mains and audio cables and the QB-9 DSD will simply wake up when the computer starts.
