On this site, you'll find lots of fans of Denon & Yamaha receivers. Mule made a great point, either go with a receiver with good power reserves (like Denon's 3806 or Yammies 2600), or a lesser powered one & save the $$ for external power amps.
Martin logans are nice, they are placement picky, off axis response can drop off, but if you're in the sweet spot they sound good. Go with what you fall in love with, you'll be happier longer!
