Bill O posted for me the trouble I was having with feedback from only the left and right front speakers when my headphones are plugged in to the 9 7 5. I start to hear them at about 17 decibels. The center speaker and Surround speakers have no noise. It doesn't matter if I'm listening to a CD or DVD on the Blu-ray player or I'm streaming from my android phone with a screenbeam Mini 2 I still get feedback.
I bought the 975 Jan 21st.
