I own the SONY XBR65X800H 4K HDR ULTRA HD TV and I can tell you that the sound from the TV amp/speakers alone do not do justice to the sound signals (5.1, 7.2, and Dolby Atmos) offered by HD programming, most DVDs, and Blu-ray. A sound-bar setup would be an improvement over the TV speakers, but to hear high-quality sound you will need to add a home entertainment receiver and speakers. An excellent receiver match for this TV is the SONY STR DH790. Watch for sales, it is very reasonably priced and it features up to 7.2 sound and Dolby Atmos. Naturally, the quality of your sound also will depend on the quality of your speakers. The "booming" sound you desire will be provided by your subwoofer. Another reason these two SONY units are an excellent match is because you need only a single remote. The TV power-on function automatically switches on the receiver, then switches the sound signal from the TV speakers to the receiver. Powering-off the TV also switches off the receiver. I have my SONY STR DH790 receiver and speakers set up for 7.2 Atmos, even though, of course, most programming at this time is 5.1. I am very pleased with this TV/receiver/speakers combination. The sound (and surround effect) is spectacular -- even when I listen to 5.1 or 7.2 through my headphones connected to the receiver!
