Why pay 3X for a Samsung HT-TXQ120 home theater system instead of a HT-TX75T? What's the difference?

Answer 1

The HD-TXQ120 upscales to 1080p, which is the big one.    All in other capacities, the HT-TX75T has better features, such as 1200W, 5 disc player.

This day and age, I would not see 1080p upscaling as a justification to spend $1200 compared to $400.

If there is a bigger difference, then Samsung needs a better web site.  I compared the specs side-by-side.
