Would love a multi-room set-up, but then remember my Edinburgh flat is so bloody small I can hear data dribbling from our backup drive in the living room everywhere in the flat. Bigger flat, then fancy sound system...
We recently bought a Sony KDL 815 TV which came with a Sony soundbar. The TV's great, but I'm not overly impressed with these soundbars. We stuck it on the spare TV in the bedroom. Sure, fancy features (bluetooth, RFID, USB & optical), the the sound quality is... well... a bit like sticking your head inside a tea cosy (shh, I'm being English) - which I have to admit is marginally better than the 15-year-old hi-fi it was previously connected to - but no great shakes. I've still got a pretty good amp & 'proper' Sony speakers on the big TV in the living room. Those are 10 year old too. Vastly superior without the feature overload.
Between the AppleTV, Mac Mini, PS4, iPhones, iPads, smart-TV apps and various MacBooks in our flat at any given time what I need is really good headphones, not another hi-fi device.
