The XE-7 shares it's chassis and many components with the Leica R3 and they are the quietest SLR shutters anywhere. One thing to check carefully is the automatic function. While my XE7 and XK still work perfectly, my R3 is erratic on auto(only auto), and this is a shared mechanism between the Leicas and Minoltas. It also seems related to lack of use and is not worth repairing
