There is no question that Yamaha produce great sound,this is a lovely piece of kit, well made and very good looking, gives crystal clear sound both in music and films, dead simple to set up, although you may want to tweak it a little to suit your own requirements, It will not reproduce the same effect as a full surround system, what I do like is that it seems to seperate the sounds well, eg it can do speech and bass nicely at the same time, £650 might sound a lot for a sound bar but its very good. It replaced a Philips HTL 5120/12 soundbar, having changed what was apparent was that the Philips for a third of the price was not a lot worse, and for its price of under £200 is really good value, sure it does not have a seperate sub woofer, but the bass is acceptable especially while listening to music. I also have a the latest curved Samsung soundbar on my TV, which I have to say is not as good as my Yamaha, it lacks clarity which the Yamaha has in buckets. Plus the Yamaha cranks up to BIG volumes, which the Samsung does not. If you are spending a lot of a 4K TV then buy a Yamaha YSP 4300, but bear in mind its very long at 110cm and quite deep. I am very happy with mine its a classy sound bar, for £650 I doubt if there is any better out there. I have yet to hear what a £1000 plus sound bar is like, it would be interesting to see, but I personally think it would be marginal, the more I listen to my Yamaha the better I like it.
