We all went potty about this when amazon were clearing it for about £390 some six or so months ago - now Richer Sounds are clearing their last few for even less! This amp has all the bells and whistles, and blows all others in its class out of the water:
"Engineered for high-end home theatres, the STR-DA2400ES elevated standard (ES) 7.1-channel receiver features sophisticated A/V technology that reproduces the latest audio formats from Dolby Labs (Dolby Digital +/Dolby TrueHD) and dts (dts HD/DTS High Resolution Audio). Expand your listening options via the Digital Media Port input and enjoy music on your MP3 player, PC or XM and Sirius Satellite Radio. You'll also see the difference with Faroudja DCDi Cinema technology which upscales all your video sources to 1080p when connected through HDMI to a compatible HDTV. Additional features include a 100-watt power amplifier (8 ohms, 20 Hz - 20 kHz, 0.09 percent THD), BRAVIA Theater Sync, an easy-to-use graphical interface and four HDMI inputs that are compatible with 1080 60p/24p, Deep Color and x.v.Color video signals.
