I've been using my Denon for, hmmm, 6-7 mos now and I'm still finding out new things on it every-so-often, mainly from asking questions on the forums instead of trying to deciphre the Manual from Hades. You'll love the Denon, but you may end up with (more) grey hair as you try to figure it out

Half of communication is listening. You can't listen with your mouth.
