I am running a pair of RF-7's with an Adcom 5400 (125 wpc). Last night I picked up a Yamaha M-80 (250 wpc) on e-bay. It was suggested I need to install in line fuses between the Yamaha and Klipsch. Is this something I need to consider? If so, where is the best place to find needed items (Radio Shack)? I will be using everything the Yamaha can give and dont want to damage my treasured Klipsch. Thanks for your time...
