Well I have had my Receiver for about 4 months. Now after reading the manual about 400 times I am ready. First thing I need to know is what calibration DVD to use. Avia or Video Essentials?? I just purchased the sound meter from Radio Shack. So far so good. I have The JBL speakers Studio Series. Most people say there Bright. And I will agree with that. For some reason new out the box JBL's sound bright to begin with then settle down. I really noticed it with my rear speakers. I bought the rears about a month after my fronts. I was really thinking about returning them. Because you could hear the tonal difference from rear to front. But after about a month they settled down. WOW incredible. Thanks for any help.
