Can I add a post-amp to this..JVC RX-DV31SL DVD.

Just getting into higher end products and have a matched set of Definitive speakers w/powered sub. Can I use an amp with this receiver for HT? Or should I sell it and work towards seperate componets? The integrated DVD is a great feature and would like to retain that. link below for specs on the unit. your input is greaty appreciated. Thank you.
If the unit has pre outs then you can add an amp of choice, but seperates will always yeild better sound.
YOu can use an amp IF the product has pre-amp outputs.
The specs on that unit are not very good...try "Outlaw Audio" for a good budget system.
