Ok, I decided to go all in on the Airplay multi-room system for the house. I'm using the Philips DS8800W for each of the 4 rooms. I also have a 5.1 system in the upstairs media room, that is ran by a Sony DN-1040 Airplay Receiver. Then each of the 3 TVs have a 3rd Gen AppleTV. All this connected via two Airport AC Extremes (one upstairs and downstairs), with a ethernet connected 2009 iMac as the media server. I said all that to say that I want to add a airplay enabled sound bar to the living tv. I've looked all over for one that supports Airplay natively and I found two. Both are over $1,500 each. So I can ignore those. Is there one that I'm not finding or can I just plug in a good soundbar via optical to my living room AppleTV, then via HDMi to the tv and get the same effect? This is the last piece of the puzzle to complete my multi-room airplay system.
