Hello everyone, my first post. I have three questions. 1st, I have a denon poa 2400a amp. during a thunder storm, something happened and it never worked again. I checked fuses they were ok. Is it worth repairing ? 2nd I have klipsch classic II speakers, and I think I need new diaphrams in tweeter and maybe midrange horns. do I have to go to klipsch or can I find them cheaper some where else? 3rd Is it better for me to use a BBE sonic maximizer or a soundcraftsman equizer
