Can anyone help me. For the second time within a month I've blown 2 tweeters. It started after I bought my lovely Marantz CD6002 CD player but this may be a red herring. I'm using the Marantz CD player, an old Pioneer A-400X amp (50W @ 8 ohms, 70W @ 4 ohms). The volume meter never goes past halfway. Bi-wired Monitor Audio cable 5 metre lengths bananna plugged both ends. Thanks folks !
