I've been wanting to upgrade my setup for a couple of months now, but I'm not sure at all what to go for. (and I'm just dying to spend some money!!) Here's my system: Harman Kardon AVR-310 Acoustic Research S50 mains AR S20 surrounds AR 4C center Sony SA-WM40 sub Sony DVP-NS400 dvd player Panasonic 27" tv (cheap one ~$350) Here is what I've been thinking about upgrading with: Sherwood AM-9080 amp SV sub Panasonic RP-91 dvd player CD player (100+ disc capacity) I am definitely not looking into upgrading receiver, AR speakers... I really only care to make one upgrade at this time. I could afford all of them..but don't feel like shelling out $2000 for it at this time!! Does anyone have recommendations?? I am probably a 75:25 - music:movies kind of guy. My personal reasons for/against the above: Sherwood amp - have only heard good things about the Sherwood..and would surely improve my sound ($500, used) SVS - same as amp desc. ($500) panasonic dvd - probably not notice a big difference, as my tv limits me (although the tv is VERY good for its price); on the other hand, I have a DVD audio disc and would be interested in more ($300-400 used) CD player - I have tons of CDs and am constantly switching CDs in my single disc player; it seems like a good CD player costs LOTS Does anyone have recommendations?? I am probably a 75:25 - music:movies kind of guy.
