Damm that's service... Steve I'll be giving you a call.

However I'm happy to report that it's not my PSR-2000 causing the problem. I took it to my wife's grandparents house, and voila no static noise from the tweeters. All I noticed was just a little "white noise" from the speakers. Some never even notice this noise. I think it's a combination of the wiring in this place and other factors such as (local TV station ant. in the area), and other things in my home.
