Well, I have had the 886 for 2 months and it finally got quiet enough in my house to set up the 886 Audyssey. I used it straight out of the box with a few manual tweaks since November. After some intial missteps on my part, the dang thing sounds fabulous. Listened to Saving Private Ryan and the beach and the bridge scenes were out of this world for staging and sonic motion. My 990 sounded as good but it was alot harder to get right. I am just starting to get into the features of the 886 because they are so extensive.
