Denon PRA-1500 vs Denon DAP-5500

Not sure where I can get info on these. hHe Denon site does not have info that I have found. Can anyone tell me which would be better to run with a Denon POA-2800? My Receiver is 2 Ch DRA-697CIHD. The receiver has Preouts and Main in terminals, can I run the preouts to the POA-2800 and go without a PreAmp?
