The A7 is Bowers & Wilkins latest music system crammed with anything it needs to satisfy a demanding modern taste. For the audiophile sense, the elegant A7 comes with a 6-inches Kevlar-reinforced subwoofer, four high-quality stereo drivers, two Nautilus-signature tube-loaded tweeters, five dedicated audiophile Class D amplifiers and a 24bit DAC. The music can then be streamed via Apple’s AirPlay, ethernet, and both an analogue or optical aux-in port.
