You don't have to blow
your speakers to hear it.
Just pause while playing a regular DVD and then put the Onkyo volume above 70 and see if you can hear the hum.
I usually never had the volume above 40-45, but some DVDs have quite a low volume recording and I had to increase the Onkyo volume above 60 to fill the room and that was when I first noticed it.
It eventually drove me mad to the point of returning the 605, which was otherwise a nice AV.
I am now uncertain about going for the 606 or just upgrading all the way to the 805.
