AnthraX1,
I'm not sure exactly what SuperWhite is - perhaps it is a limited technology that is proprietary to Sony. If you can't see a difference, it might be best to keep it off. I don't see why it would case any damage if it was on, but PQ being almost idential, it might be wise to just leave it off.
As far as the speakers, they support whatever sound comes through them. The kbps rating should have more to do with dynamic range and overall quality than a spec that could potentially break or even age the physical speaker cone. You should feel comfortable setting it to any range offered by the PS3.
I hope that helps.

I have a playstation 3 plugged into my ln40a650 and there are a few options that I have questions about because it says only turn on if your TV supports it and I can't find the information anywhere ONE is does this TV support super white? I turned it on and it works but I don't know if it even supports it or is even making a difference. Also there is an option for different quality sound 128kb/s etc and when ever i put it to set automatic it puts it on minimum and I go to manually put a higher setting higher quality that is and it says make sure your speakers are compatible or else it can cause damage. What is the specifications for this on the speakers if you want to know the exact settings I can choose from ask for them.
