Loudspeakers

System Audio says its Legend speakers represent a 'world's first', as they can be upgraded to active/wireless operation through the addition of its Silverback amplifier/electronic crossover module (£1800) and Stereo Hub (£400 when purchased at the same time). For the Legend 40s, the former splits a claimed 300W of amplification across the drive units, and introduces DSP that results in a boosted low-end performance down to an anticipated 20Hz. The Silverback module caters for analogue line and digital network sources, but for greater wireless freedom System Audio's Stereo Hub uses WiSA technology (not your own Wi-Fi network) to support 192kHz/24-bit streams. The hub also includes a range of inputs including analogue line, and digital optical/coaxial, USB and HDMI. Additionally, it integrates Apple AirPlay, Chromecast, Spotify Connect and Bluetooth. The Silverback's WiSA connection also means it's compatible with other WiSA streamers, such as Primare's SC15 Prisma.
