Love Mirage speakers. Currently using the discontinued Mirage OMD-5 (omni-polar.)
(I missed Tapioca's post above - oops!)
As for receivers, I'm with StylinRed on this one. I'm a fan of Yamaha but currently using an Onkyo. Denon, Harmon Kardon and Pioneers are pretty good but you have to figure out what you want to achieve before throwing money away.
