This post is a question back to Little Miss Lena on the quote "after some tweaking over time". I have posted under "To Hiss or Not to Hiss" my initial experience with the model 950, less than stellar so far. I too have the hiss problem, or perceived problem. This hiss is very audible at the listening area about 10 feet away. Do you have any suggestions on some "tweaks" that may help reduce this or is it worth trying another model 950, maybe I got a bad apple?
