I've noticed, mainly with my center channel, a very slight static sound coming out of what seems to be the tweeter, when I'm watching DVD's. I have a Kenwood VR-507 "rated" at 100 WPC which is of course laughable because I'm sure it's not running near that with all channels driven. I have a Paradigm cc-170. The receiver volume goes from -100 to 0.. and my normal volume for watching movies is somewhere around -30 to -35. I notice the static sound only at the beginning of dialogue and usually when it's things like S, and T at the beginning of word, though occasionally on loud dialogue it will continue through part of the sentence. It's also normally when things are shouted. I noticed it more with "School of Rock" this weekend, but also noted it occasionally with "LOTR:TTT SE" in DTS last night. It's not bad, and it's not something that really bothers me except that I'm now listening for it and it's concerning me. I'm sure nobody else notices it because I'm being so particular and listening so closely. Is this something to be concerned with? Or is it a function of my equipment... namely my 2 year old Kenwood receiver, and 3 year old Sony DVD player.
