Link your router to your Sonos players to extend the range of your existing network with this Sonos BRIDGE BRIDGUS1 wireless bridge that features a 2-port Ethernet switch for simple connectivity. The connect button makes setup easy.
Even though I own one of these to give greater flexibility in terms of moving Sonos Play and connect components as the mood strikes me, it is not a necessary component of the system. You can create a Sonos system without the bridge if you are able to connect an Ethernet cable from your switch or router to just one Sonos component; the rest can all be wireless.
What's great about it: Flexibility of component locations
Sonos Play:5: The Play:5 offers 5 amplifiers and 5 speakers for room-filling, crystal-clear sound throughout your entire home. Wirelessly stream your favorite playlists, Internet radio stations or your own music library, and choose which rooms you want to play your music in for a customized listening experience.
After trying air streaming audio from my "I" device, and also trying a networked receiver as a means of streaming audio hi-fi and being very disappointed, I decided to try Sonos. This is a rare case where I was blown away by the sound quality, ease of use, and speed of response. It took a bit of playing with the system to get everything integrated with my RAID 1 NAS, but after working that out I could not be happier with the end result. After many years of experimenting, I have finally realized my dream of having access to all my music (>30k songs) anywhere in my home. This is truly a case where you get what you pay for. The Play 5s are worth the additional expense, but the most impressive results are with the Connect through a quality amp and speakers. The overall concept is flawless.
What's great about it: Sound, speed, intuitive, access to large music collections
What's not so great: A bit pricey, pairs required for good stereo imaging
