We had a demonstration of this last Friday, our thoughts are that it certainly is works. Large rooms are a little difficult for it still leaving a space for the Yamaha, yet the Samsung has a true rear surround sound speakers, which are wireless (each powered by the mains) allowing you t experience surround sound from a soundbar solution like never before.
We were very impressed with the Atmos considering what it was doing however you could not compare it to a dedicated system with in-ceiling speakers.
As a solution, we could not fault it in anyway, it delivered exactly was it said it would, making it ideal for anyone who wishes to experience Atmos or even surround sound via a soundbar solution.
