I just got back my 950 from blue dot upgrade and am noticing the the same popping on my right rear center. When the 2 channel amp(adcom 545) running the rear centers is off. the popping goes away. This was occuring durng cable channel changing and it happened when the iput signal changed from 2.0/0 digital to 3/2.1 digital or PCM. Our HDTV decoder is connected to our 950 via an optical connection. I have not verified that the same popping exists when switching sources (i.e dvd to cable or laser.) Anyone else having similar issues after their blue dot upgrade?
