From what I can see, it looks like it is mostly the Sound United Family (Onkyo/Integra/Pioneer) that seem to support it amongst the usual suspects.

 

To clarify.

Sound United don't own Onkyo / Pioneer or Integra - they are owned by a separate private equity firm based in the Cayman Islands. Don't bet on them being around for long either, they haven't made money for half a decade now and have just announced plans to cull 30 percent of their workforce and 50 percent of their executives.

The chances are they will pull out of producing AV products for consumers and instead focus on the OEM car business and licensing their brands to whoever wants to put them on the front of their TV's / microwaves etc.

What this means for their on-going tech support, updates and warranties... who knows, but basically at this part of the brands life I would think it's a case of 'you pays your money, you takes your chances'.

Onkyo / Pioneer / Integra work with Sonos, but you require a Sonos Connect, not a Sonos Connect amplifier.

Beware, because of the connection to the amplifier, there will be considerable latency in that zone due to the network to analogue signal path...

Sony also do the 'works with Sonos' thing. By all accounts when Sonos updated their app a while ago it broke the Pioneer / Onkyo / Integra iteration for roughly two weeks, but the Sony's kept on trucking.

Denon / Marantz / Classe / Polk / Definitive Technologies are owned by Sound United, they use the HEOS multi-room system instead.
