Hi. I just bought one of these used in excellent condition not quite a month ago. We both have the same questions and my research has yielded the same results. I can say the build quality is fine as well as the layout of the controls. I haven't had much time to give it a long evaluation on its sonic qualities, seems someone's always doing or watching something, but there is nothing about it that I find irritating so far. I ordered a manual for it just a couple of days ago to fully appreciate some of the features. Since I had just got a Carver PM-700 for a steal ($190 including shipping) and a pair of JBL L5'S ($125), I couldn't resist buying the CT-7 to have a matched set. I have them driving those JBL's and for the $501 I paid for the trio, I doubt I could do much better with spending double the money.
