Samsung is aiming to provide their customers with a nice warm sound by including the vacuum tube, but it’s an aesthetic choice as well. You can see the tube from the front and top of the unit, which gives it the look of a much more expensive component. Of course, the HT-E6730W does plenty more too, like play 3D Blu-rays, upconvert streaming and DVD video to 1080p and stream content through Smart Hub.  It’s available now for $999.
