I'm down to the Denon 3808 vs. Marantz 8002. I am about 80% video/20% audio, so I'm leaning towards the Denon as it hs 4hdmi vs. 3hdmi for Marantz. Currently, I'd use 2 hdmi inputs (PS3 for gaming/blu-ray and DVR), leaving 2 open on the Denon and 1 open on the Marantz with everything running to the Pioneer Plasma through 1 hdmi. I can't think of what else I would hook up via hdmi (because I wouldn't get a 2nd gaming system or a dedicated Blu-Ray) which is why the Marantz is still in contention, but something makes me more comfy about having 2 free vs. 1. I suppose I could get the DVR back to compenent if pressed way in the future as that is how I have it connected now and it looks more than fine. Also, I like the volume leveler to keep commercials from being so loud (even though 50% of viewing is from the DVR and I fast-forward through commercials).
My biggest concern would be reliablity (although I know both are champs) in case I don't buy from an authroized dealer. I guess it's like deciding between a Honda and a Toyota
For main/centers, its Energy Veritas 2.2i/2.0 vs. NHT Classic Three/matching center. Cost is no object (Energy=$1,325 vs. NHT $1,250).
Had Klipsch before and don't like anything overly bright though I doubt either of these would be on that level since they don't have horns. I have a 12" Velodyne sub that I use sometimes so I'd want the monitors to have decent low-end.
Interested to see what your choice would be.
