It did, indeed, arrive; what a glorious sound! I took a couple of pictures of the packaging (mine arrived in pretty much perfect shape) and size of the speakers for those of you still wondering about it; will post in the next couple of days.
Looks like I don't have enough room in my living room for 7.1; so I bolted the surrounds to the walls last night for a 5.1 setup and plan to run speaker wire to them this week...hopefully I'll be able to convince my wife to let me pull the couch out from the wall a bit to put the other 2 behind it, but that's not likely.
I really don't like the looks of the bookshelf speakers, nor the fact that I had to spend another $60 on mounts that will actually hold them; and the wife acceptance level is hovering around zero. Fronts and center are livable, but those surrounds are just plain ugly and inconvenient.
Just to be clear, from a non-audiophile's perspective the speakers sound TERRIFIC, even with the included speaker wire and just kind of set around the room ghetto-style. The auto-adjust works well with a few tweaks, as mentioned; but it takes more like 5 minutes (rather than one, like I've read here), and everybody has to be "very quiet"...not easy with a 3 year-old in the room!
Oh, and I'm not sure where I'm going to put that HUGE sub...but I'm ok with that.
First Impressions: 1) this is a great system! 2) I hope your room is big enough to use the full 7.1; 3) your friends WILL be jealous!
