I have a pn58b650 and it does buzz. But honestly I have my onkyo sr-tx-607 pushing Klipsch RF-82's, RC-52, RS-42's and RW10D. It is better than the movie theater in my opinion. And even late at night when I'm not listening to it loud I notice my refrigerator kick on more. Got to love open concept homes. I would not worry about it. I also have a 42 inch panasonic viera in my bedroom and it does not buzz at all. I love the panasonic and it was my benchmark, but the screen size i wanted left not to many options. I really believe the samsung to be the best value. I really love it. I would have had to go to the panasonic v10 to get a slightly better picture and an extra $800.00 no way I'm super pleased with my purchase.
