Samsung D7000 buzzing

[Ferrari Fan]

I'm just about ready to get the 59D7000 and all the talk about buzzing has me somewhat hesitating. I know plasmas buzz abit. I have a Pioneer Elite PROFHD1 and can barely hear it with volume off, and my ear next to that tv.

I have been to two different Best Buys to see this tv, and have not really heard anything. Now granted, Best Buy is not too quiet, but I have put my head right up to the tv's in the store and really can't hear buzzing.

The 59D7000 will be only for tv viewing with Directv, and on occasion using a smaller size, though very good quality Polk 5.1 system with it. But mostly, I'll use the built in tv speakers ( girlfriend factor as she dislikes louder, better sounding Polks ) Also, we'll be sitting directly in front of the tv and about 10' away.

So, after all this, my question is how loud on a scale of 1-10, with 10 being the highest is the buzzing ? And with the volume on is it really that noticeable ? Thanks in advance.

Anybody that owns a D7000 or D8000 please respond weather you do or don't have any buzzing. Again, thanks in advance.
