Congratulations, Keith. Your system already sounded awesome at the end of the last session, so I can only imagine what improvements are possible... I look forward to hear your first impressions!
BTW, I bought the Denon DVD3910 after I heard it at your place. I use it mainly for the SACD/DVD-A capability. With regard to redbook CD performance, it is very good but I still prefer my CD player, Ah! Njoe Tjoeb.
Considering the potential of your downstream equipment, you might want to consider modding your 3910 to make it even better. There are already several alternatives like Empirical Audio, Audience and Modwright.
