Wheres my week link????

I would like you guys or ladies here at the gon to give me your advise. I currently just listened to dynaudio contour 54 powered by all naim cd pre amp. I was impressed but yet I thought my system sounded good. I just recieved my Mc45 pre that is going into a mc 207 feeding my B&W 802n. All signals are being given by Marantz 9500 multi player. Ive been playing it all night wondering where why what I thought sounded so good does not anymore? I dont feel that I have the detail the other system had my system also sounds like it rolls 1 note into the other now. Opinios on what I should look into are greatlly appreciated. By the way I know im using a surround amp Im going to be debating wether to get rid of it and get a 2 channel or replace all my speakers and go surround again. I will base my decision on your advise and research all your oppinions from there. Thanks in advance!
