Yep exactly the same as you. I took a long long look at the Onkyo and decided I just couldn't do it.I have just purchased the Denon, after changing my mind about the 606.
I popped into Richard Sounds, and when I saw it in the flesh, was surprised how big, and ugly it was!!!!!!!
From a features point of view, I am led to believe they are very similar.
The only thing I would say, having read through a number of different threads, is that the Onkyo seems to kick out a lot of heat!!!!!
