Hello there, I am looking for a budget receiver and the Yamaha RX630, Onkyo 600, and Denon 1802 came into view after a bit of research. Which to choose? I am planning (not sure yet) to drive a pair of Paradigm Monitor 9s, cc270 or 370, and probably atoms for the rears. Is it a crime to use one of these budget receivers with these speakers? From what I have been told, there will be no Onkyo 600s around me until late April the earliest and so I am wondering whether it will be worth the wait. I would really like to get my HT started within this week. Also I can't find many reviews of the Yamaha RX600, so I would like to ask if Yahama usually produce solid receivers?? Any qualms with any of the receivers listed? Maybe you guys have better suggestions (want to spend up to $500)? Thanks for any input in advance!
