I am either going to buy an SVS 20-39 sub or a Marantz 8200 receiver for Christmas. Which would be the best to get first? Which should have the most impact on my system? Right now, my system consists of: Paradigm Monitor 7s Paradigm CC-370 Paradigm Mini-monitors Paradigm PDR-10 sub Yamaha RX-V596 receiver My main concerns with my system are: --2-channel music listening is bright and not as musical as I would like. --Appx. 7-10 db drop in mid bass from 85hz - 180. (result from bright sound?) --My sub now is OK for now but I will be moving into a larger room by January (room will be 20 ft by 15 ft). --A more musical sub/ high impact movie sub sure would be nice! So what would you do in my situation? Will going with the new receiver make music sound THAT much better than adding the new sub would make with the bass? Thanks!!
