Got the 2100 yesterday, tore out the HK and cried a little inside. That thing is a beast, probably weights 3 times as much as the new Denon (looks way better too!).
Anyway moving onward got it plugged in and setup then ran into issues with the HTPC connecting thru it. I've had this Win7 MCE box for years connected directly to the TV with HDMI and spdif to the HK without any issues. Throwing an AVR in between has reminded me about how much of a pain windows display/HDCP can be. I've been messing around with taping off pin 19 on the HDMI cable, etc but so far it's not working very well. I may have to switch back to having the HTPC send video to the TV and audio to the AVR. At least my growing number of other devices have a home finally on the AVR. For so long I've done 100% of everything thru the HTPC but those days are slowly dying.
