Thanks for the detailed response. Much appreciated.
The more I think about it - the more I believe that a sound bar is kind of a compromise while looking for that movie theatre like sound. With the sound bar I would probably only be able to 'up level' the current Bravia sound level.
The Bravia TV I have is non android so it leaves me with the YAS 109 with HDMI option. Personally am not a very big fan of Sony sound as I feel they do get heavy on bass and leave out lot of the mids (dialogues). Now that you mention it - Yamaha seems to be a good option with the Sub out included (Also planning a Taga active sub for my Sonodyne bookshelf setup).
I think it would probably be a Yamaha YAS109 along with the Taga sub that would be the setup. I may have to move the sub from the bookshelf to the TV setup on occasions of watching Marvel and Nolan movies - but hey it would still be worth it I believe.
What am not sure of is how would the sound bar manage the cross over frequencies - guess we will have to try and see. The YAS 109 also looks like a globally popular model but like all globally popular audio components - very difficult to audition in India.
Current focussing on adding the sub to the Sonodyne bookshelf setup. The sound bar will probably have to wait till the Diwali sale
