JM Lab Diva Utopia problem - need help


Hi,

I am using a pair of Diva Utopia Be. Today, I noticed the sound from the mid range unit of one channel become very funny, it become unclear with background noise. The tweeter works fine and so is the woofer. If I put the amp into mute, there is no noise. I switch it to another power amp as I am using monos, the problem is still there. So I figured it can be the speakers. Has anyone experienced the same problems?
