Sony has introduced Network Audio System in summer of 2005. And again thanks to Sony's skillful marketing (sarcastically speaking), I learnt about it just a few days ago in February of 2006 by browsing MySony site. There was a press release in Europe and that's about it. I do not think Sony USA has ever done anything about promoting it here. You might ask what is so great about this system? Well, when you first look at it, the design looks kind of futuristic. It has a network function allowing you to stream your music from any PC in the house and what's more, it is even compatible with iTunes. This can be done by using your wired LAN or if you attach a wireless converter (that is my setup at home), you can enjoy your streaming wirelessly. Another plus, it also has a WEB RADIO function, allowing a user to stream any internet radio station. As you will see in the pictures, the unit has omni-directional speaker system which creates a wide acoustic field. Here are some short descrtiption of the system: Sony’s NAS-CZ1 Network Shelf System allows you to stream music from your PC to any room wired w/ Ethernet within your home network. Fitting nicely on a shelf or table top, the NAS-CZ1 is versatile when it comes to enjoying your music in various locations of your house.

Rated at 40 Watts (in operation) and including 4 tweeters and 2 subwoofers, the NAS-CZ1 provides you with powerful, clear sound ideal for any single room.

When you start the Network function on the player it will search for available servers and let you choose which one you want to use. If you are like me that has several VAIO systems in the house, it can also use VAIO Media servers. You can also choose to have it automatically connect to one specific M-Crew server. User Profile (up to 5) allows different users select their preferred server and therefore music stored. Organize your Playlists, Albums, Favorites, etc. Nice Info Panel shows all kinds of info from network state and configuration to Music titles: Top: Connections in the Back: Neat Remote: Documentation and Software Sony also threw in a long thin network cable and Loop Antenna Screen Shots of the Software: Supports AtracPlus up to 256 kbps as you see in the above screen shot. WEB RADIO set up screen: So as you see it is an interesting model. You can always stream/play your music from your desktop but you cannot always place it in your living room (unless it is a pretty VAIO PC ) as it messes up with your decor or your Mom's decorating style.
