Im Jim by the way. Live in central Ohio. The MX's from what I have read are kind of a rare breed. They were mostly sold in miliatry px's. The great thing about them is the 4 ohm and 105 db sensitivity. I too mostly listen at near field lower sound levels and the Sansui 2000x powers them fine and has a wonderful sound to it. Unfortunately I have an issue with the left channel distortion and from what I read this is common. I am looking into having a total rebuild of it. I have never had a receiver rebuilt but I love this one so much I am going to have it done.
