Hello Experienced Enthusiasts, I am in the process of upgrading my Home Theater with a new receiver. I currently have a very low end Pioneer Receiver that I cannot wait to get rid of. I will give you my system as it is now, then the receiver that I am considering purchasing. If anyone can add any insight or advice as to which model might work best for me, I would be very grateful: Receiver: Pioneer DSX-557 Front Channels: Definitive Technology BP-2000 Center Channel: Definitive Technology CLR-2002 Rear Channels: Definitive Technology BP2X DVD Player: Pioneer DV-414 TV: Toshiba 32" Remote: Home Theater Master MX-500 Environment: I live in a town house with a very large, open living room and vaulted ceilings. Within the next few years, I plan to move into a house. I am also an avid video game enthusiast and have a Playstation 2 and Nintendo Gamecube hooked up to my system--my wife loves my hobbies. I am most seriously considering the Harman/Kardon AVR-520, mainly because I have several hundred dollars in gift certificates to Circuit City, but also because it has received very good reviews and seems to be very exapandable for future components. I have done plenty of research on-line about different receivers in the price range of $500-$1,000, but it is difficult for me to compare the true value of models. Any recommendations are very much appreciated, even if you have recommendations as to the ideal setup of my system or if you have a particular favorite brand. As a true novice, I was a fan of Pioneer receivers (whether that was a good choice or not is another issue), but now as a novice-intermediate, I would like to find a brand that I have a lot of confidence in. Thank you all for your help.
