Sonos
I auditioned a squeezebox, and liked it. But, I also tried out a Sonos system, and LOVED it! It is awesome to be able to stream music all over the house, and have everything playing at the same time! I sent the squeezebox back, and haven't looked back. I have my replayTV linked to the sonos using ethernet cables, and I can stream any recorded show to any TV in the house using the sonos wireless network. I also have my cd players linked to the sonos, so I can play a CD in one room, and listen to it all over the house! (although this isn't necessary, since all my CD's are ripped onto my computer using Apple Lossless). The sound quality is great with the digital toslink connection, and I highly recommend it.
