Sonos system supports almost each popular media format, including contenders like WAV and MP3, beside with less common ones including FLAC, Ogg Vorbis, Audible audio books and Apple Lossless format.

System also supports streaming of any analog device attached to any ZonePlayer, though Sonos controller does not have ability to control such devices itself. Neither can it do miracles like changing CD in a deck nor are switching on power to your DAB radio, so there restrictions to power of Sonos wireless system.

This is not to misjudge its networking capabilities. SonosNet is designed on mesh principle, with every ZonePlayer attaching to next closest available unit rather than to a single, possibly distant, access point. This approach gives many advantages, including:

• Redundancy: If a ZonePlayer goes offline, network keeps on to work. Any players attached to dead zone will just find next near available zone and carry on as usual.

• Minimal interference and degradation: Since signals are travelling shortest possible distance between nodes, possibility for interference and signal decrease are decreased to minimum. This is very important where audio is concerned, mainly when playing synchronized audio, as any drop outs and delays are clearly visible. Actually, such glitches are rare with Sonos system as long as ZonePlayers are not placed too far apart.

• Expandability: Including new client devices to a standard wireless network usually degrades performance by increasing load on network's hardware. SonosNet is an exception to this rule. Including ZonePlayers to system develops performance by successfully increasing many access points and reducing distance between them.
