One of the simplest out there for worth, choice and shipping!
The HT-D6730w is very smart for the price and looks to possess corrected the problems that you could have examine by the top users of the HT-C6930W.
The sound is as good as my eight year old Onkyo system which cost $1500. though my Onkyo is healthier designed with polished aluminum speakers/AV and a AC power sub (the Samsung is high gloss piano finished plastic) the processing for surround looks to work better with this Samsung system. (Modern technology) at it best 
The system is very well packed in its box and took me as much time to unpack it because it did to line up, about an hour from start to end and looks/sounds nice with my 65 DLP TV.
I was alittle confused gazing the image and solely counting 5 speakers plus sub; how could or not it’s 7.1 the 2 front tower speakers is 2 separate speakers in one. so by counting them twice you return up with 7 plus the sub. the two rear wireless speakers have wires that head to the wireless AC power module and then it communicates with the AV receiver wireless across the room. The sub does not need a separate AC plug-in, which was shocking to me, but works very well.
The blue-ray player does not have a commence tray, however direct feed like a CD player in a very automotive. The up scaling works nice and normal DVD’s appearance as good as HD. The second to 3D isn’t dangerous either. I place in Polar express (standard DVD) movie and clicked on second to 3D along with the 3D sounds and my youngsters simply loved it . One button push on the remote to urge to Netflix is another plus.
Again, for the price this is a very smart system!
