Marantz 5300 -- Best Speaker Match

My ear is not being helpful, so I will ask your thoughts. What are the best speakers that my 5300 can drive on its own and do them justice? I would love to get some Paradigms (haven't heard them tho), but I have read that they are not a good match with Marantz receivers. Is this true?
What is your price range? Room size? 5.1 or 2 channel?
paradigm are better with nad products,,marantz ,,not too sure currently i have tryed mission ,,m series which are good for the money,,,,maybe psb would seem like a better match,,,get good cables though
