I'm very satisfied with the YAMAHA, but have a few little things that prevent the fifth star: - No printed manual "on board". Of course, a lot can be done intuitively, if you connect the device equal to a TV, because then everything can be read on the screen, but it is still no explanation or help to do so. Therefore example, I had only download the manual on the net and read before I have the ARC channel set up correctly, so that it makes with my Panasonic TV for a perfect sound. - The outputs for the speakers - as unfortunately in most amplifiers - very "tricky" and also too narrow for me together ... I have fairly large hands and it is a "Fuzzelei" to install all the cables properly. Here I do not understand why the entire manufacturer not proceed to the back anzubrigen ports to which you can attach banana plugs, for example ... Otherwise, I am very satisfied so far and look forward, what he delivers in connection with my Dynaudio speakers for a beautiful sound.
