I currently have a Pioneer VSX-D1S that I purchased back in 89/90. It has Dolby Pro Logic for surround sound (I know) and even has the DVD player button labeled as VDP (Video Disc Player) *(Seeing how old this is). Anyway I use it only as a pre-amp and have it connected to an Adcom 555 that I bought back in 91 , and that drives my Infinity RS Kappa 8's. I would like something that is more modern but still able to use my Adcom amp and provide me with a more up to date surround sound (at least 5.1). My wife watch mostly DVD and TV and sometime listen to CD (Holidays and such) Here is my current setup Salamander Triple 20 with Extended High Rise TV Pioneer PDP 5060 Cable Box Scientific Atlanta 8300HD DVR Int Amp Pioneer VSX-D1S Amp Adcom 555 CD Sony CDP=C77ES DVD Sony DVP NS725P Graphic Equalizer BSR 14XR Front Speakers Infinity Kappa 8's RS Infinity Center speaker and Infinity Bookshelf speakers for the rear I will eventually be updating the DVD Player to use HDMI connection as well. Will I need to have a subwoffer or will my current speakers work well with current surround sound designs. Any information or advice would be greatly appreciated.
