2) I already know all of the above as stated before, Im just wondering about the hissing/whine. There should be no difference between my setup and your previous setup, but I have a noise difference. I was wondering if there was any new information regarding the source of the whine ( I believe Barry NJ has it) or if in fact this "slightly louder than an NA" description I read about and the "whine" are one and the same.
