I just got the xbr79x900b from buydig (on ebay) for $3499, which I found on slick deals). Buydig is an "AUTHORIZED" Sony Dealer for warranty purposes. They shipped the TV rather quickly, it was huge, the feet are already attached on the 79" model. (The sale was over after 100 units, but just today 8-26-15, they started selling 100 more.. Search slick deals for "4k tv Sony".
Honestly, I don't mind the speakers at all, the black gloss looks nice to me. Also the sound is really great. My wife accidentally turned off the stereo and was using the TV and she couldn't tell the difference, lol though her shows (soap operas and dramas) don't require a subwoofer! LOL. I can pretty much be sure that if I got the wireless subwoofer for this TV that it would cost you $600 for a stereo that can beat the sound of this TV.
3D works great with the latest firmware update. I read that the 79" uses an LG LED display which would explain why my side viewing angle is great. I sit off to the side where our main sofa is center to TV.. I know on my old TV the viewing angle issue was noticeable on this one, not at all.
However because it might be using the LG LED, I think the picture levels are different to that of it's 65" x900b counterpart that everyone raves best picture ever on LED. Don't get me wrong, my picture quality is amazing and I say that to my wife every time we watch the TV (still in honeymoon phase), but it took me a lot of tweaking to get the picture to my satisfaction. I HAVE NO LIGHT BLEED WHAT SO EVER, so I guess YMMV with this TV, but mine is perfect).
Right out of the box the picture is beautiful, but they really set the contrast high to show off the blacks and such. Well, if there is a shade of grey in the scene or something in the shadows, I want to see it.. But I don't want the picture washed out.. Therefore I'll share my settings with you and tell me what you think (on your new Sony 79" 4k 3D LED).
I chose to start with Standard instead of Cinema 1 which so many others do.. I'll try tweaking Cinema 1 in the future, but for now I'm using standard. Also remember that every mode/input uses different settings, so you'll need to customize each separately. (i.e., even though my Satellite and Smart TV are both on INPUT 1, they still use different picture settings because it's in a different mode)
One thing you need to be sure to do is go into "Setttings" / "Preferences" / "Eco" / and turn your Light Sensor off... At night it made the TV way to dark.

There ya go everyone.. Have fun and enjoy 4k!
OH One last thing, the 4k Upscalling on this TV is amazing, best I've seen.. Every show that is 1080 or 720 looks like 4k on this thing. It's seriously amazing compared to an 80" 1080p TV, you can get so close and see no compression or artifacting. standard broadcast 320 x whatever, still looks like crap in 4k just like it did in 1080p.
