Summary: I have always been a Sony guy so this might be one sided, but I bought this for the 5.1 ss since I had only been with the sound bar, I wanted something with more sound more power and this is definitely that. It also has a hidden features on it for anyone that has 4kHD TV, this Blu ray player has a 4kHD setting on it, the blue tooth works excellent.
Summary: The first system I was sent was defective. However, I now have a brand new system. This system is awesome and loud. The interface is easy. I don't have a 3d, 4k, or smart tv. My tv is 1080p. The Bluetooth is awesome. I like this surround and the sitting in the theater feeling it gives me.
Summary: so far I like the system. it will take some time to get use to controlling all the functions it seems but I only tried it one session. sound is good but not as good as my older Sony. the speaker set up was easy even the "wireless" speakers.
Summary: I had a Onko 7.1 suround sound in my old house ( much Bigger) I really did not want to bother with crawling under the house to run wires. this was the best set-up powered back speakers. I cannot tell the difference between 7.1 and 5.1 The Sub wooffer is not a AC powered plug in, but I have been very Suprized/Happy on the power of this subwoffer. I have had no problem cranking it way up and blasting out the house next door. no complaints.....Yet!
