FYI
I own a semi decent 5.1 system and I have bought 3 different yamaha soundbars.
Yamaha blows the water out of Sonos in the soundbar category. It's crap for the money. £1200 for the bar plus a sub. That gets you a top of the range Yamaha soundbar which will destroy most setups.

Yamaha YSP-1600 Soundbar Review
Should I buy one?
At current prices, the Yamaha YSP-1600 is a great buy in the sub £400 soundbar category. The build quality is top notch and connectivity options, including an HDCP 2.2 compliant HDMI input capable of accepting 4K signals up to 60 frames per second, are almost equally as solid. You also get integration with Yamaha's excellent MusicCast system, turning the YSP-1600 into a networked audio streamer and/or part of a multi-room audio system. This 5.1 digital sound projector also lives up to its name by actually being capable of producing sound behind the listening position, courtesy of eight 'beam' drivers that can be adjusted for different room layouts. It's equally at home with movies, TV and music, too, so whatever you throw at it, the Yamaha sounds accomplished and refined. The only negatives we can mention are a somewhat cheap feeling remote and that the system can sound a little thin in the bass department with those low frequency effects in movies, although you can add an external subwoofer if you like, but that doesn't stop the Yamaha YSP-1600 from coming Highly Recommended.
What else is there?
The first soundbar that came to mind as an alternative is the
Q Acoustics M4 which is highly comparable in terms of sound quality and costs roughly the same but it lacks HDMI connectivity, if that’s important to you. Also priced at £349 is the
Samsung HW-K550which doesn’t sound quite as accomplished as the YSP-1600 in terms of its all-round capabilities but it does have HDMI connectivity and slightly more low-end thanks to a dedicated wireless subwoofer. The
Cambridge Audio TVB2 is another one to consider and that sports 4 HDMI inputs, sounds comparable to the Samsung and is priced at £329."
