Sonos has updated its multiroom digital music system. Here's our review of the Sonos ZonePlayer 120.

In early 2005 Sonos introduced the basic building block of its multiroom digital music system: the Sonos ZonePlayer 100, a combination digital music streamer and amplifier. Since that time, the ZP100 has gained lots of new capabilities through software updates, but the hardware itself didn't change.

Now, more than three years later, Sonos has finally released a new version, the Sonos ZonePlayer 120. Although that gap is an eon in technology years, don't expect huge differences in the new box.

Zone Players are the heart of the Sonos system. You place them anywhere in your house where you want to hear music. Add the company's CR100, a handheld controller designed a bit like an iPod, and you can play music in all the zones of your house - either the same music everywhere or different tracks in different rooms.

The various pieces of Sonos hardware communicate among themselves through a wireless mesh network that the devices automatically set up.

(Earlier this year, Logitech released a less expensive alternative, called the Squeezebox Duet. But its streaming devices don't include an amplifier - they have to be connected to your stereo or to powered speakers. See Logitech Squeezebox Duet review.)

The new Sonos ZonePlayer 120 is 35 percent smaller than the ZP100, thanks to an extruded aluminum case that acts as a heat sink. (Sonos doesn't use any fans to cool inside; in our tests we didn't feel the unit get hot to the touch, however.)

The company also claims that it has doubled the wireless range in the Sonos ZonePlayer 120. Reliably testing wireless range is difficult because of interference from other wireless sources or because of obstruction by walls and windows, but we did find that we could use the system in the far reaches of the building, something that was occasionally a problem with the older Sonos hardware.

The Sonos ZonePlayer 120 also boasts more audio power, 55 Watts per channel, up from 50W per channel in the older version.

In addition to the Sonos ZonePlayer 120, Sonos has refreshed its ZP80, a zone player without a built-in amplifier that you can plug into your existing stereo system. The ZP90 is the same size as the original, but also boasts improved wireless range, according to Sonos.

OUR VERDICT

If you already own a Sonos system, the new Sonos ZonePlayer 120 offers no compelling reason to upgrade, unless you have significant range problems. But for new buyers, the updated hardware should make the system even more reliable, especially in large homes.
