Considering these two receivers for an upgrade. I've found the HK for about $150 less than a B-stock 3805 w/mic. Actual power and features seem fairly close. From what I've read the HK has better room correction that includes the sub. I have a PC-Ultra so not sure if this would be needed or if it would give me more options for tweaking? The Denon has the Denon-link, but I don't know if I would ever use this as I don't have a Denon DVD player and will probably hold off on any upgrades in this area until for at least a year. Was also considering the 950/7100 combo or the new offerings from AV123 (Emotiva). Probably higher quality, but with less features and more expensive. Would either of these sound $400-$600 better than the receivers? Looking for best bang for the buck. I listen to 70/30 HT/Music rarely going above 80db in a small to medium size room. At this time using monitor series from Paradigm, but would like to upgrade to Rockets or Swans down the road.
