If I were buying from BB, I would get the best Yamaha my wallet would allow.
Buying a Yamaha or Denon from the net is scary, but I did it. I wanted a better product than was available from BB.
From my recent research, I am leaning more towards Denon. It has taken 3+ years of reading, and studying manuals to come to this conclusion. I am a very happy Yamaha owner, but Denon has a slight edge in what I now prefer.
I don't spend much time checking-out Pioneer, but I am sure they are just as good. All depends on what you need it to do, and what will be connected.
