Hi, I am looking to buy a home cinema system. I am interested in the Dolby Atmos 5.1.4, 7.1.2 or 7.1.4 setups but have a budget of $800. I'm really looking for the cheapest option that will give me one of these setups, preferably 7.1.4 though. I would also like the system to include a 4K UHD Blu-Ray player, the back (and side) speakers to be wireless, and have no tower speakers or overhead speakers (speakers would be upfiring/Dolby Atmos enabled). The system would mainly be used for TV & movies but some music as well. The TV room is quite large and is open to the kitchen. We would often turn the TV to face the kitchen so would need to turn off the home cinema system then. The TV we have is a Philips 4K 49" Ambilight 49PUS6401. I do not currently have an AV receiver, amplifier or Blu-Ray player. I am quite new to this so it would be helpful if you could not use any technical terms or just explain them to me. Thanks.
