Recently i listened to E60 speakers and could hear a distinct hiss from them while listening to the dialogue from the the center channel EC25. It was quite distracting. I placed my ear close to the speakers and found a "hiss" sound coming from the tweeter region. I don't think there was any interference as wiring was throught the wall and the other equipment was at a safe distance. What could this be? (The receiver was working at about -10 dB). Anyways, I am going to buy E80. Does anyone have these speakers? If yes, how do you find their performance and is there any hissing problem? I have also heard that E80's come with additional spikes.Is this correct or do I have to but them separately? Thanks for the help.
