LR separation has improved a lot. Earlier, I was 13 feet away(as per Audyssey), with speakers 6 feet away. Now, I am 7 feet away(again as per Audyssey), and speakers are 6.5 feet apart. More equilateral that before.
Atmos and surround effects are beautifully subtle, rain does pour down, birds chirp, a baby cries on the far right and slightly behind, and so on. The attention is drawn to the sound, and nkt the speaker
Subwoofer is bang in front and firing away.
This is the first time where I haven't fiddled with Audyssey much (apart from venter +2dB) and loving the envelope of sound.
