Actually just the opposite. D-Premier, 120, 200, 400, 800 they are all essentially the same. It is the most user friendly piece of gear I have used. Sophisticated, yes but the entire thing is set up using a configurator online. You can play with it here; http://http//en.devialet.com/configurator/advanced
Click on an input to activate or disable it, click the carrot to configure.
