This is a USED Rotel RSP-980 in good condition. It has 4 DSP modes, Prologic, and finally THX Cinema. It sounds great in stereo as well as surround, but at the moment I just dont have any space or need for this unit. (for you lazy people it DOES come with the remote). Also, while it does not decode DD, it has 5.1 channel input that will work with a DVD player that decodes DD. There is one sort of glaring flaw with this unit and that is that the switch in the back that controls whether or not the center channel is active is missing. This can be repaired by any Rotel authorized repair center, but as the switch was set at Center "ON" there was no need for me to repair it since I had a 5.1 system. I'm not sure how the switch fell out, but I never had any problem since it was set to have a center. Feel free to email with any questions! $180 shipped CONUS!
