The Sonos BOOST  is retailing for S$199 in Singapore.
It is retailing for US$99 (S$141) on Amazon  and doesn’t ship to Singapore directly. Since the price difference before freight forwarding is only about S$60, it is not really worth getting it over at Amazon.
Sonos BOOST creates a dedicated wireless network for use by Sonos and hence it eliminates interference from other wireless devices on your existing Wi-Fi.
The reason I bought the Sonos BOOST is because I have issues connecting my second PLAY:1  to my Sonos network. The second PLAY:1 is connected via LAN as well and it manages to receive an IP from the router. However, my iOS Sonos controller is unable to connect to it. I tried factory resetting my second PLAY:1 and switching off and on my router again but that didn’t work.
It seems a few other people also encountered the same issue of unable to connect the second Sonos to the Sonos network .
Using the Sonos BOOST, it works fine and I guess in terms of wiring, there is only one power wire to my PLAY:1s which looks neater.
