That's a decent amount of power the 4306 is putting into 4-ohms, even if the 4806 had only a 5% increase of the 4306 it sounds like the difference of using my Aragon amp at 300wpc in 4ohms and using the Denon's amps would be relatively insignificant.

A computer once beat me at chess, but it was no match for me at kick boxing.
