Just ordered this for delivery on Monday : Playbase.

I'm sold on Sonos at this point. Getting a tour of their business eroded the last of my resistance. To me the cost is well justified, and will likely keep my lifetime audio TCO lower. Wireless helps keep it flexible in my apartment living situations, and would work well if I settle into a house again. Having the speaker + system as one unit is nice too, since the Sonos speakers are really good quality.

The Wirecutter does have a good what's coming up section for possibilities from other vendors. For me, I have enough confidence Sonos will survive or be acquired by someone like Apple preserving my investment.
