i notice you have the onkyo 801 listed.. the only main difference between the onkyo 801 and 701 is that the 801 has the net-card, for direct linking to the computer to play music files from your computer. unless that is a valid option, or something you will ever do, then look at the 701 instead. it is same wattage, same inputs/outputs..
you can find the 701 for around $500 bucks.. i have one, and love it..
