If you mean
this system, then I would say yes it looks like a pretty good set up. One of the problems with most HTIB is they are hard to upgrade. At some point you will want to upgrade or add something.
ETA: I looked up the Sony unit at the Sony web site. It lists power on that unit as:
Audio Power Output: Amplifier: 1000W Total, Center Speaker: 143W (1KHz 10%THD), Front Speaker: 143W x 2 (1KHz 10%THD), Subwoofer Speaker: 285W (1KHz 10%THD), Surround Speaker: 143W x 2 (1KHz 10)
To me this is red flag stuff. They wanted 1000w total power so they pushed till they got it. 10%THD is a high amount of distortion. Compare that to the .7% that the $1000 system's amp shows.
Unfortunately there are no standards for rating wattage. (I vote for 20-20khz @ .05% THD for the standard.)
