I used to have a Marantz SR7001 Receiver, and the speakers that were best for all-types of music on this amp were Mirage OMD-15s. $800 for a new pair, on vanns. Amazing all-around speaker.
One other option to consider is active speakers. I have some Quad 12L Active stand mounted speakers that are explosive in their ability to go from absolute silence, to full volume. They have amazing detail and just enough warmth to not be clinical. I got mine for $750 new. This means you no longer need to worry about the amp in your receiver. It will just be the preamp.
Anyways, good luck.
