"Bassy" isn't a function of the receiver; that is setup. Marantz reliability is just as good as Yamaha, as is Denon, and while I like Yamaha, I'd pick Denon or Marantz over them; but that's just me. If anything, Denon and Yamaha are actually the most neutral or flat sounding to me, while Marantz has a bit more "color" to it and that tends to sound good with music. For movies, they all sound the same to me. Though the receiver does influence the sound somewhat (implementation, their EQ methodology, etc...), your speakers and the proper setup of them have a FAR more significant impact on the sound of your system.
