I used to have a receiver attached to 7 speakers. I was tired of messing with all of the unsightly cables and decided to go with a Sonos Arc. The Arc can process Dolby Atmos better than other soundbars, but it's not really an immersive sound. Here is where the Sonos Era 300 come in. I added two and paired them with the ARC and the sound is unbelievable. I hear sound coming from the front, sides and above--the immersive feel I was looking for without the mess of cables. Of course, to play Atmos, the source must be recorded in that format. If not, you will likely end up playing Dolby 5.1--which still sound great on these speakers.
