I have the Marantz 7500 paired with M60s and I am very happy with this receiver's quality. It does everything that I could want and the sound is amazing. Personally, the Denon sound just wasn't for me. The other contender at the time was Yamaha (2500) because of it's equivalent features, but I found that the Yamaha/Axiom combo was a bit bright for me. So, I trusted my instincts and went with the Marantz, which has been well worth it. Pairing this receiver w/ the clarity of my Axioms, I now truly hear the music and not the receiver's coloring of the music.
Good Luck
