After about a week with the 50G25, I am going to say that the buzzing is not acceptable to me. I had the volume off this morning and could hear a noticeable buzz (not high pitched) at 8 feet.
I have read this and other threads thoroughly, but am still not sure what my best remedy is. I am between having Amazon send a new set and having a Panny service person come out. Normally I would request a new set, since this seems to be out of spec (yes I know some buzzing is normal, but this is noticeable) and it is a brand new piece of equipment. However, am I going to go through another delivery, break-in, etc. just to wind up with a service visit anyway?
