I concur, the debate on weather or not an external amp provides significant sound enhancement is constantly ongoing. However, no one here would likely ever dispute that your Denon 3806 is a great receiver/amp combo and that it will sufficiently drive your M60s to louder than healthy levels with ease.
I'd suggest trying out the Denon and if you still feel the need to experiment with external amps later to see if you can go even louder, cleaner then you can always certainly do so. I myself am impressed with the power and clarity of my Denon & M60 combo on a daily basis and feel no urge to add more power, except maybe for the bling factor.
..and if you do decide to add externals, make sure you come back to give us the impressions of your changes.
