I have the Outlaw 950 but in another room have the Parasound AVC-2500. I am thinking of getting the 990 to replace the 2500. Sound wise would this be an upgrade or downgrade, the 990 compared to my old Parasound AVC-2500. Will keep the amp if I go with the the 990 it is a Cinepro 2k5 & add a 2 chamnel amp. But looking for sound quality not the latest bells & whistles.
