Query: Just a note about sound for Yue Zhang

Yue Zhang, I am not sure if you will read this review. But in any case, a general note about sound. This TV comes with so called "Perfect sound" set to on. I didn't know about that for a while. Out of the box the sound was VERY low. One day I thought it is not possible for a unit this good to have such a lousy sound. Then I found the "Perfect Sound" under the Setup-Audio, turned it off, and voila, I got great sound! Hope it helps folks who didn't thinker with Audio properties of this TV.As a more general note, I have the unit for more than a year, and I like it very much. Even though it is not true HD (1080P), the picture is great. Also, I leave in Austin area, and when it is on Air, it picks up 4-5 over the air HD channels with impeccable quality.
