Hi all, I'm little curious what you guys think about my experiences. My system consists of Denon 4802 as pre/pro connected to Lexicon NT512, Denon 2800 as DVD and CD transport, Diva Swans 6.1, 4.1 and C3 center channel plus SVS 20-39 PC subwoofer. Before purchasing an amp I was very happy with my system but because of this forum and numerous postings describing experiences with going into seperates I've always wondered what I'm missing. After I hooked up Lexicon amp (same as Bryston 9BST) I've started serious listening and to my surprise there was only a slight improvement in sound than from using my receiver alone. So i have two questions: Is Denon 4802 such a great receiver that it can compete with high-end pre/pro's and amps out there? From my understanding Lexicon NT512 suppose to be one of the best. or Are my speakers, CD and cables not good enough to let me experience the difference? I use Monster Cable speaker wire and Outlaw interconnects. What I want to add is the fact that to me Denon 4802 alone outputted incredible sound and addition of an amp only improved it slightly (not night and day). My system is calibrated using RadioShack sound meter to 75 db for speakers and 80-81 db for SVS sub. I also visited couple of my friends who own Lexicon MC-12 and Classe SSP-70 or 75 (can't remember) and their systems were very close in sound quality to mine, which is three times cheaper. I'd like somebody to help me with to solve that puzzle.
