I just bought the Denon 2105 and was quite excited. After hooking up my plasma TV and DVD, however, I noticed that the video and audio were out of synch just a tad - likely due to the processing time. I see that both the 2805 and 3805 have an audio delay function that will (hopefully) fix that.
I understand that the 3805 adds the digital SACD capability, but I'm fine with analog given that I'll barely use the SACD feature as is. The 3805 has a HDCD decoder but I can't seem to figure out what that is.
Any other major differences between the 3 that I should consider in my decision (other than price of course!)? Recommendations? I'm looking to keep this receiver for at least 5 years and don't want to be too short sighted now.
