A:AnswerHello I just recently got this as my first Receiver, it doesn't support spotify or Alexa, which I don't mind. But overall I still like it. For speakers you can go with a 5.2 setup or 3.2.2 setup
Dolby Atmos & DTS:X
A:AnswerTrue Dolby atmos requires that you have height speakers. Height speakers are mounted on the ceiling and shoot sound downward, or they can be upward firing speakers that bounce sound down from the ceiling. When playing something in dolby atmos, the reciever will be able to play it but you wont get true dolby atmos unless you have the height speakers.
A:AnswerI don't know. One has to visually check out the connections. Are they rca, bare wire, optical, HDMI. Don't just listen to the sales man say" Oh, yeah, it'll connect to anything." Visual inspection of plugs on both units is highly suggested
