Picked up this set from Best Buy today for the bedroom. I haven't gotten around to tweaking it much yet, and the wife is asleep in bed, so it'll have to wait.
I like the sound in Movie mode, though. Good bass and clear vocals. I'll try out some acoustic stuff tomorrow.
I'm replacing a Sony CTS-150 "surround" kit, and I definitely like having actual rear speakers, and they're small enough that the Mrs. doesn't mind one on her nightstand. I've got the "sub" on the floor between the bed and my nightstand. I like this position better than the Sony wired sub, which had to be up front, and in our case, on top of a 1930's school desk.
I have an older Sammy plasma without ARC or HDMI out, so it took me several hours to finally realize how to get both my mini Genie and AppleTV connected at the same time. I think. I hooked it up, but haven't messed with it yet.
All in all, I'm pretty happy Day 1. I'll report back.
