I suppose it's difficult to pinpoint where the phantom channels should be exactly, seeing how we can't see them
Obviously you can follow the sound very precisely which is the main thing. Like previous setups I've had where say a spaceship goes from front to rear, you have that drop off sound in the middle, where as this glides all the way from the front to exiting behind me without losing it at all.
I've also noticed I'm hearing a lot more detail which I never could on the Sonos setup. Take the original blade runner scene where it's raining and he's waiting to order his food (near the start of movie). There's more voices, footsteps, sounds in general just going on.
While the movie is proper looooool, watched Moonfall last night and that makes good use of the sound. Plan to revisit Gravity tonight as that sounded very good on the Sonos, so should be very good on the Sony. Also need to make time for Hobbits and LOTR movies again.
