Can anyone out there offer some advice ? I have been using the Marantz SR4200 connected to Mission M71's, Mission M7C1 center and some M70 rears. When playing a dvd, this happened with first my playstation then with a Harmon Kardon DVD25, I have to turn the amp up to -18 to -15 to get a reasonable listening volume. The amp only goes up to +13 !!! I am using decent interconnects and cables, do not have a large room and sit about 10 feet from the system. Any ideas ?? I will be looking to upgrade in the near future.
