Sony STR-DG800 7.1-Channel Home Theater Receiver with HDMI Passthrough (Discontinued by Manufacturer)
Great AV amp with 2 HDMI inputs and 1 out to HD TV
This unit makes it easy to hook up your HD DVD and HD DirectTV box to your new HD TV with the use of the HDMI cable to attain the best possible connection between them.  The sound is just passed through and you can still feed a digital audio out from the TV or DVD player to the amp for sound.  A super reasonable HDMI solution with plenty of power for a 5.1 surround speaker system like the Klipsh Quintet III ( with matching 10 or 12 in. powered SUB) Are their better units out there--sure, but not for under $500 or $600.  This unit is the best value for what it does.
