Do you have or are you planning to buying an 1080p HDTV? Do you have or are you planning to buying an Blu-ray or HD-DVD player? Do you plan on having the ability of decoding Dolby True HD or DTS-HD Master Audio from an HD player? What is the size of your room? What is the power handeling specs of your speakers?
Here are some recomendations: Denon AVR-2808ci $1,200 Denon AVR-3808ci $1,600 ***** Denon AVR-4308ci $2,500 out of your budget but it is really nice
Marantz SR-601 $1,200 (DOES NOT have HDMI 1.3a and no decoding for Dolby True HD, Dolby Digital Plus or DTS-HD Master Audio).
Those are the three mid end receiver company's that I highly recomend then the back up Marantz. A company called D&M Holdings actually owns Denon, Marantz and McItosh. The Denon AVR-3808 is getting rave reviews and is being purchased by a number of members of this forum. And is the receiver that will most likely replace my current Yamaha RX-V995 5.1 surround receiver.
