jami w.
just being me thats all
to be honest the only difference that ive heard an listened to is that they both have round the same wpc but if im wrong i will be told lol the 4400 is a quad reciever. me personally i dont like the quad recievers the 2325 is becomin harder to find cuz its highly diserable. personly i love all the marantz recievers tape decks r2r tt ill get it all if i can find buy it welcome to ak btw. these recievers r very very underrated at wpc techinicly mine r 125 wpc but ive had my first one test an it didnt clip till it hit 185 wpc these recivers can run there peak wats all day long w/o melting to a pile of molten larva, but in general they r the same but just in quad to answer ur question search around fer some other links that will help u out alot better than i echowars, an a couple of other members have more knawlege than i do
