I have a Marantz 7702 processor and an Auro 3D immersive home theater. The 7702 can only engage up to 11 speakers at one time. That means in whatever immersive format I listen I have to forgo either my wide channels, my rear surrounds, or a pair of height channels. I have an opportunity to pick up a Circle Surround processor I can use to engage all of my speakers. So now instead of Atmos 7.1.4 I can have Atmos 9.1.4 or Auro 14.1 instead of 10.1.
If anyone can comment on the Circle Surround it would be helpful. Thanks
