As the Fidelio A9 system is equipped with Wi-Fi it can be connected to your whole music collection whether it is stored on your computer, an external hard drive, a networked NAS drive, media server or in the ‘cloud’. The ‘AirStudio’ smartphone app detects all the connected music sources in your home, including internet radio. Simply dragging your finger across the screen connects that device with the Fidelio A9, making your smartphone the principle music controller of the whole house. The system comprises two speakers; one passive and the other with the amplifier and networking hardware built-in, which connect to each other with the supplied cable. This handsome bookshelf set offers tremendous value for money and is bass-reflex loaded through rear ports, for deep and extended low frequencies.
