Sonos will soon release a firmware update for its ZonePlayer S5 speaker system that will allow two of them to operate in a stereo system, each designated as a left and right channel. A WhatHiFi report reveals that owners of more than one S5 can select which one is designated as a right channel and which one as a left. This will let users listen to each on their own separately, such as in different rooms, or together from a single source for a more room-filling experience.
