Denon AVR-1804 Harman/Kardon AVR-230 Pioneer Elite VSX-41 Please give me your opinions on which is the best performing receiver. They are all in the same price range. I am looking to spend a max. of $400 so if you can recommend another, that would be appreciated as well. It would be used for HT 90% of the time. I would like Multi-room function if possible but is not absolutely necessary. Thanks.
