I recently purchased a new big screen TV and I am now looking for the audio system to go with it, but I am torn between the Onkyo 696 and the Harman Kardon AVR520. My speakers will probably be Polks (rt35i's front, cs245i center, rt15i's rear, and pws350 sub). 1) What opinions do you have of these receivers? Which brand is generally considered better? Do you suggest any other receivers in this price range? 2) The opinion of Polks seems to be split 50/50 on this board. What do you think of this speaker combination? Is there any thing better out there for the same price or cheaper? If so what? I have been looking at getting a surround sound system for the past 5 years, and I am now finally taking the plunge, please help me!
