No problem with sound quailty in my opinion. Mine sounds fine.
Here is a review if you are interested:http://www.televisioninfo.com/conten...eview-1032.htm
The review is very good and close to true. I agree that the Black Levels are great on this TV, and the Color Acruacty is good, but could be a little better. Skin tones are good.
My biggest disagreement with the article is it mentions "artifacts" I have had this TV for almost a month and have yet to see an artifact. I have it set to "smooth" as well.
I have had many LCDs to date (or setup), and love this TV. The PQ on Standard Def actually surprised me, and HD is great. The screen has a little more gloss then my others, but it seems to add to the PQ a little.
Check out the review as it does a good job.
