I'm not sure about your specific stove, but I have a Camp Chef Everest stove. This is the adapter I've found that will allow me to hook up a larger size propane tank. Probably will get it soon and just use the 1 lb. tanks for my lantern.
[laughs] Yeah, my Optimus (similar to yours) makes a bit of noise on full-throttle but I can't justify the expense of the damper. My feeling is I WANT the stove to be loud enough to warn people it's on...no good to have someone step on it or knock it over. :)
FWIW, one thing that could be useful is the ability to burn bulk propane from BBQ tanks. There are adaptors for that, too.
EDIT - to be clear: I'm not trying to convince anyone to buy anything; only sharing info about things that exist. :)
This works for me.
