I recently replaced a sunfire grand theater 2 with an integra dhc 9.9(kept sunfire amplifire). I have enjoyed the features and such but I keep hearing a 'pop' with the sound stopping. This is when I am watching or listening music. When playing music from an xbox 360 the sound had at least a second or two of stoppage at times. It seems to be when the volume is a bit higher. I have tried multiple devices for input and all are having the same problem with some being more noticable. I do not see switching between different sources when this is happening or changes of any sort but it keeps occuring with louder sounds. Anybody have an idea for this? I had some incidence with the sunfire pre-amp with this but only with the xbox 360 and it was usually associated with a game.
