Getting music to all the rooms of your home can be an expensive task, especially if you have to run wires. Sonos has been selling network multi-room music systems for a while now that can stream tunes wirelessly to speakers in any room of your home. Yesterday, Sonos announced a pair of new wireless music systems and it has announced a software update.

The Sonos 2.6 update is available free to all Sonos customers. To entice users to install the new software update Sonos is offering free music worth $200 to those apply the free upgrade or register a new Sonos system. New features with the update include support for SonosNet 2.0 and MIMO, support for larger music collections on NAS or PCs, and support for Mac Leopard OS.

The wireless mult-room music system developers over at Sonos are releasing some new players to update their line of products. These are the Sonos ZonePlayer 120 and ZonePlayer 90, priced at around $500 and $350, respectively.

The Sonos ZonePlayer 120 offers up what the manufacturer says are “advances in power supply design, digital amplifier engineering, industrial design, and mechanical engineering.” These all amounts to what is perhaps the best ZonePlayer to date. The ZonePlayer 90, meanwhile, is more of a basic unit.
