Fuse Upgrade to Ceramic not glass

Been researching fuses and see a need to upgrade to Ceramic over glass but don't neccesarily buy into the hoopla over expensive Fuses, I would say getting rid of any glass type for ceramic is the way to go , I truly believe thats what people hear the difference in , ceramic is a much better material for acoustics than a crap glass / thin wire that can Vibrate and be a weak link in my opinion I'm not about to spend a fortune on fuses either a quality ceramic will suffice. Question where does one find out what fuses are in his gear ? I want to figure out what I need for my Marantz before I take it out of my Rack and spend time  , open her up just to figure out what I need is a big time waster. I called marantz they referred me to a svc Dept but they couldn't tell me either , Is there a way to figure out what I need to have it so I can do this project in one shot?? or maybe I have ceramic already and dont know it , breaking my rack down to figure out cant happen.
