Denon 3910..What next ?

My 3910 has served me very well. I am getting that upgrade bug and am wondering what to try next that would make spending 1000-1500 worth it.
I want to stay with a universal as I listen to DVD-A,SACD as well as DVD's fed to my CRT TV.I am not looking at HD yet .
I have a A.A. Prima for cd's .
I live in a very small community so auditioning is out of the question.
I would like to go the "used" route .
I have read good things about McCormack ,Lexicon .
Would very much like other suggestions.
