I've already switched around everything possible L/R audio, balance, receiver/amplifier, source, digital/cd/pc/bluray player. Journey's starting piano notes in "Faithfully" put out the worst distortion/scratchy sound out of all songs I have this problem with. I've have isolated it to the right speaker tweeter. Occasionally I get some crackles from some driver on the left speaker, but it's too hard to track down. I wonder what could have caused this? I didn't really notice this in the first few days. But i think the problem is getting worse. Or either I'm just now noticing it more now because I am aware of it.
