I picked this over Onkyo, Pioneer, Harman, Marantz etc..because I personally prefer Yamaha's sound quality,
And this receiver did not let me down.
It delivers great sound to each channel with enough power.
Also, this is very easy to use, and display set up (GUI) is very helpful as well.
You can edit input names, set distances to speakers and so on...superb!
Menus are straight forward, and remote control is very simple as well.
It could have been better if the buttons on remote were back lit.
HDMI in and out works superbly,
There seems to be a a second of blink when changing HDMI input to/or out of my Mac, but this only happens once at the beginning.
To be honest, it is the first time using HDMI, so I am not too sure if this happens with other receivers as well.
Receiver is much lighter than other receivers I had before,
but filled up with all the options I needed.
Very happy buyer.
(UPDATE 2012.01.02)
Cannot be happier,
It got even better after a month.
Sound tendency is somewhat warm, which I like.
